    The below is interesting as the assumption from some on here was that the 33.3 was totally representative of conditions in Ireland and the UK at the time.

    "The reanalysis also compared the temperature recorded in Kilkenny to six other weather stations, including in Birr, Phoenix Park, Roches Point, and Sheffield in the UK.

    These stations have nearly complete records through to today, many of which have been digitised, according to the study.

    The maximum surface temperatures of the selected weather stations for June 1887. The red point marker shows the maximum surface temperature recorded at Kilkenny on 26 June 1887.

    “We can look at the modern day differences between those and when we look at the date in 1887, the Kilkenny Castle difference is either entirely outside the distribution of expected daily occurrences or right in the extreme of that distribution,” Thorne said.

    so the temp recorded was 4C higher than the next highest temp from the country that day? evelyn cusack seems to be having none of the traitor talk though.

    I'd find it interesting for them to say this 'was it near a wall of the castle that might heat during the day and expel heat' while saying the temperature recorded in Phoenix Park is possibly the hottest temperature recorded in Ireland.

    You can make several arguments against the PP station in terms of the stations location, no less with a building close by which would equal a potential flaw that he thinks would contribute to the Kilkenny reading being possibly bogus? Musicman18 (I think) gave a detailed break down of the layout yesterday and put it very well how the station as is would get warmer readings than if it was located just outside the OSI grounds. Yet he considers the PP reading unimpeachable, which based on the idea that the recording instruments are modern/accurate is *fine* - because that's not in doubt, the 33.1c reading 100% happened yesterday and is official/correct etc. But many posters on here have said the instrumentation for the 1887 also was proven accurate and working, right? If he applies scrutiny to both instances then maybe he should be settling on the 1976 reading of 32.5c as the best fit record based on some of his arguments perhaps?

    I don't mind if someone has an issue with the KK reading, it certainly does seem a out-there thing from some angles. And I didn't know the WMO discounted it? But I wouldn't be trying to remove a historical data point and record just to state a known heat trap station is the actual hottest day ever and the narrative that could go from that (I feel like a lot of people don't like our heat record is so old and we can't break it). Our climate has the data to show on average things are warming here, we don't exactly need the hottest temp to show that either. Let's get the 33.3 someday without needing to delete anything for now.

    An interesting read nonetheless, thanks!

    Doesn't fit the agenda of course.. ;)



  • Registered Users Posts: 1,525 ✭✭✭Hooter23


    The record temperatures in the UK today are also false...the cities are so big these days and there are so much concrete and tarmac it raises the temperatures by many degrees that what they actually would normally be without all of this...even in winter time you can see this mentioned on forecasts where temperatures stay above freezing in cities while the surrounding countryside is frozen solid because the temperature difference it causes are so big



  • Registered Users, Registered Users 2 Posts: 1,363 ✭✭✭dePeatrick


    ‘What is not questionable, he said, is the reliability of the 33.1°C temperature recorded yesterday in Phoenix Park.’


    Don't know how he can say that when the measurement taken in PP is in a sun trap near concrete buildings, sure, that was the temperature there but not elsewhere. If the Kilkenny measurement is questionable then the PP one is too using the same criteria.

    It read 36 in my jeep yesterday so that'd the new record, I even have a picture



  • Registered Users Posts: 403 ✭✭Reversal


    Only comparing 6 stations, why did this study use so few?

    24°C at a coastal station such as Roche's point? Seems entirely plausible to see over 30 at an inland station like Kilkenny on a day like that. For example, Roches point was 23.5 yesterday.

    There was a 16 degree spread in maxes yesterday. Would be easy to make a chart to make the Phoenix park reading look like an impossible outlier.



  • Registered Users, Registered Users 2 Posts: 1,577 ✭✭✭Billcarson


    The record 40.3c in England today was recorded in a village in Lincolnshire, not a big city.



  • Registered Users, Registered Users 2 Posts: 8,913 ✭✭✭Danno


    I suggest that folk read this... https://www.ukweatherworld.co.uk/forum/index.php?/topic/115480-date-of-temperature-of-333-deg-c-at-kilkenny-in-se-ireland/

    Secondly, that study disregarded the fact that 30.0c was recorded in Galway that day and 30.6c was recorded in Tycor Waterford the following day.

    Killarney also recorded a very high temperature on June 26th 1887. But no mention of that in their study. They include Sheffield in England though, strangely.

    I've seen the Kilkenny figure questioned several times now in the recent decade or so, anytime somewhere in Ireland records above 31c.

    In my opinion it's as if there is a sharp focus on this temperature record in order to enhance the climate change argument. Its bizarre as in the next sentence we're told we're 100% responsible for heating above the temperatures of the 1800s, the very dataset they've doubts over aspects of!

    Mad world.

    Here's a basic map showing the maximum temps at various available stations on 26 June 1887, the day of the Kilkenny Castle record. Given the variation we can see on a typical very warm to hot day in Ireland, it looks fine to me 🤷‍♂️ second highest out of these was 31.7C at Blackrock, Cork.

    Yes - it does appear that they were perhaps a bit selective with the stations they chose.

    However, perhaps it's because these stations have the longest and most reliable set of records? I'm not sure.

    "These stations have nearly complete records through to today, many of which have been digitised, according to the study."



  • Registered Users, Registered Users 2 Posts: 3,068 ✭✭✭EchoIndia


    To be specific, I expect it was at RAF Coningsby, which is a military airfield. https://en.wikipedia.org/wiki/RAF_Coningsby



  • Registered Users, Registered Users 2 Posts: 1,577 ✭✭✭Billcarson


    Wonder if yesterday's set up happened at the end of June (as the record was at the end of june) with that bit of extra solar heating could it have broken the record? Or the fact that a few weeks earlier in the season would have meant perhaps a slightly cooler airmass and would cancel out the slightly higher sun?

    Just a thought.



  • Registered Users, Registered Users 2 Posts: 14,124 ✭✭✭✭Danzy


    You'd have a greater difference than that in County Cork alone.



  • Registered Users Posts: 33,752 ✭✭✭✭RobertKK


    Kilkenny is not typical for Ireland, it is a county with hills around its edges that go over 1000ft/300m and Kilkenny City in the centre is around 200ft/60m above sea level.

    I have zero doubt that this helped Kilkenny get the record, a record that I believe will be broken this decade, Ireland is getting over 30C more commonly that it use to.



  • Registered Users, Registered Users 2 Posts: 8,913 ✭✭✭Danno


    It is quite unique in terms of it's geography.

    Firstly, yesterday's 33.1 has been rejected and the earlier 33.0 has been confirmed.

    It's in Thorne's interest to cast doubt on the KK value as it will help keep him well-funded into the future. I find it ironic that he says this:

    “It would have been mercury and glass thermometers, and it probably would have been a maximum and minimum thermometer. [The weather station] is something that would look like a meteorological shelter that we see today, but it would have been probably smaller because the large shelters were an innovation that came around in the First and Second World Wars,”.


    “It would have been smaller and the smaller size of that would have left it more prone to solar heating effects during the day, and then coupled to that would have been [questions about whether] it well sited, was it near a wall of the castle that might heat during the day and expel heat. 

    I wonder if he thinks the same about the 48-degree reading in Sicily last year, which was recorded using an AWS in a tiny radiation shield sitting a few cm above a thick metal arm in a small, dark metal fence enclosure near a stone wall in a bare field near a road. I don't expect he does. Or about the Shannon carkpark. Or the building beside the PP enclosure.

    The Phoenix Park site has no doubt changed over time, both naturally (I assume the trees have grown) and artificially (that buildin a few steps away). Modern instrumentation does not distinguish between air that has been heated naturally or artificially, it will accurately measure the temperature just the same. Just as a mercury one will do. Using Thorne's rationale, we should reject many more old measurements because they were done before the standardisation of practices.

    Interesting thought @Billcarson

    Seas are cooler in June than July though and unless we're drawing our airflow from the southeast in over southern Wales, southern England and northern France then maritime cooling would mix in more I would think.

    Kilkennyweather give a reasonable account of the 1887 event here: 1887 The Hottest Day (kilkennyweather.com)



  • Registered Users, Registered Users 2 Posts: 8,219 ✭✭✭Gaoth Laidir


    And it has sandy soil, which is prone to more wide extremes in temperature (hot and cold). It looks like June had been an extremely dry month in Ireland, with only 4.3 mm of rainfall in Waterford, 6.9 mm at Enniscorthy, 8.6 mm at Birr, 10.5 mm at Phoenix Park, 13.7 mm at Galway. It was the second driest June on record in Waterford from 1874-2012, for example. Data here.

    Such dry sandy soil is highly susceptible to high afternoon temperatures, especially around the Summer Solstice. Higher surface temperature means higher air temperature. You could have a station out in the middle of an open field and it would still read higher in this type of soil condition.

    I didn't see Thorne mention that.



  • Registered Users, Registered Users 2 Posts: 4,426 ✭✭✭PokeHerKing


    What a pointless, biased study. Waste of money and time. If this is what climate scientists spend their time doing they'd be better off slashing tires or blocking roads, it would be more productive at least.

    So many variables involved in that thought. It reminds me of people saying "if only this was January we'd be buried in snow" when we get marginal situations in March. Let's go with what we know, ie. just another 20 minutes of clear skies at the Phoenix Park would have broken the record. Casement could have broken the record too with clearer skies. It all came down to the random nature of cloud cover.



  • Registered Users, Registered Users 2 Posts: 899 ✭✭✭DrZeuss


    The way I read it was that 33.3 may in fact have been on the low side in 1887 (if they are calling it into question) 😁

  • Registered Users, Registered Users 2 Posts: 8,913 ✭✭✭Danno


    In the E, and S. of Ireland, up to August, every month of 1887 was drier than usual, especially June; but rain came on August 13th, and the remainder of that month proved moderately wet. Had August been dry, the S. and S. E. of Ireland would have been, agriculturally speaking, ruined. The wet August saved the pastures and the root crops. Its temperature was about the average. September was dry and cold. October was dry and very cold. November was wet and cold. Of the twelve months of 1887, eight were colder than usual two about an average, and two of fierce heat. Ten months were drier than usual, and two had an excess of rainfall. The sticking feature of the year was the sudden outburst of heat in June and July, accompanied by great drought, and following a very cold, dry, backward spring.

    Spot on @Gaoth Laidir with the drought conditions. I think it was just 5mm for Kilkenny that June.



  • Registered Users, Registered Users 2 Posts: 14,583 ✭✭✭✭M.T. Cranium


    If the castle was a large structure (as I assume it was or is) and the instrument was near a north-facing wall, those factors would not be big problems for the veracity of the readings there, a large north-facing stone wall would be in shade most of the day and would not be radiating much heat. Different story if it were a south or west facing wall. In any case I have seen enough climate data to know that variations within 1 C deg are fairly standard over very short distances and they don't have enormous significance, what does have more significance is how frequently record or near-record temperatures are set.

    I did the following analysis on net-weather in support of their contest thread. The CET has been keeping daily maximum records since 1878, and this was the top forty of them going into Tuesday 19th (the new record was set on Monday 18th as shown). This list will be amended no doubt when Tuesday 19th comes in around 37-38 C. The data are an average of three locations near Luton, Oxford and Blackburn. Some minor adjustments have been made over time to homogenize the data series. You'll notice the ongoing increase in frequency of these top forty hot days in the period of record.

    how accurate were temperature recordings back in those day?? how accurate were thermometers for instance?



  • Registered Users, Registered Users 2 Posts: 8,913 ✭✭✭Danno


    That is a very good question @fryup - the above image quoted from @StratoQ's Kilkennyweather.com site explains the following:

    I have found a copy of the Report of the Meteorological Council 1890 which mentions the inspection that took place at Kilkenny Castle in August 1889 (Two years after the record breaking temperature was recorded). The report states that the instruments were all in good order. The maximum thermometer was checked against a known good standard thermometer and the correction to be applied was found to be 0.0° (i.e. the thermometer required no correction and was reporting the true value). 

    So, even two years after the record was taken, the same thermometer was checking out as being "spot on" and recording accurately.



  • Registered Users, Registered Users 2 Posts: 8,913 ✭✭✭Danno


    Yes - it does appear that they were perhaps a bit selective with the stations they chose.

    It doesn't just appear so, they were without much doubt very selective in what they chose. Adding Sheffield in there was bizarre to say the least. I went through the flies they left on git hub, they included Galways 30.0c in their comparisons there but it never appeared in the chart on the final report - the one where they put a little red box to imply Kilkenny was way out of kilter.

    The poor quality of this even shows Kilkenny incorrectly labeled on the plot chart, how can Kilkenny show a max of 29.2c for June 26th 1887 and also show 33.3c for June 26th 1887 marked by a red box? A very basic error to make on a paper entitled Reassessing Ireland’s Hottest Temperature Record, which is currently being peer reviewed and was resubmitted yesterday morning for what he hopes is the final revision. 

    Sryanbruen above spent a couple of hours pulling data from Met.ie and recreated a chart that is ten fold more professional than what this paper purports to show.

    However, perhaps it's because these stations have the longest and most reliable set of records? I'm not sure.

    If these stations have a most reliable set of records, why are they questioning the 33.3c, ignoring the fact that the thermometer used to record 33.3c was checked and found to be working! Are they investigating Markree's -19.1c recorded just six years earlier too? Or is it's validity overlooked just because it's a cold record?

    "These stations have nearly complete records through to today, many of which have been digitised, according to the study."

    Which is a good thing if the digitisation process is free from alterations such as homogenisation - i.e. just the raw data please.



  • Registered Users Posts: 1,525 ✭✭✭Hooter23


    It does not matter...there are big cities in every direction you turn over in england...the huge amount of extra heat from all these cities drifts for many miles especially in summer sunshine so even the surrounding countryside will be affected by the extra heat...more than likely all that extra heat converged on the area where they got a so called record...

    What exactly is the context of 'but there is no prospect of this station becoming one of the second order'?

    Assuming the second order were the leading/official stations or something (may be wrong, second order sounds like a cult), then Mr. Scott found something odd with the Kilkenny station that it would never be upgraded, no?

    I find it mad that there is nothing to be found on the stations exactly location. Surely somewhere, in some old record or paperwork, it's said exactly where it is. Would be a fun side project to try find it out once and for all.



  • Registered Users, Registered Users 2 Posts: 8,913 ✭✭✭Danno


    What exactly is the context of 'but there is no prospect of this station becoming one of the second order'?

    First Order and Second Order are only different really in the amount of times of recordings/observations happen - perhaps also, the amount of instruments (though this varies anyways). Think of what we refer to Synoptic and Climatological stations. Our Synoptic stations (First Order) are typically hourly manual recordings - though automatic sensors now-a-days makes some of this manual work part-time (Knock Airport) or fully automatic (most stations reporting here: http://archive.met.ie/latest/reports.asp )

    Our Climatological stations (Second order) are recorded at 9am UTC (10am IST) only - although on interesting weather days observers will look at recordings if they are available to do so!

    Assuming the second order were the leading/official stations or something (may be wrong, second order sounds like a cult), then Mr. Scott found something odd with the Kilkenny station that it would never be upgraded, no?

    Quite the opposite! Mr Scott found the Kilkenny station to be ran well, the observers keeping good records etc... that there would be no need to downgrade it to a climatological station.

    I find it mad that there is nothing to be found on the stations exactly location. Surely somewhere, in some old record or paperwork, it's said exactly where it is. Would be a fun side project to try find it out once and for all.

    I'm not aware of the exact location in Kilkenny Castle's grounds the station was located - I'm not sure if @StratoQ has ever found out, but I can ask them. It sure would be a great project to try and find out - perhaps there are very early day photographs in the Castle which might have inadvertently captured the setup?



  • Registered Users, Registered Users 2 Posts: 8,913 ✭✭✭Danno


    From all the hurling they do, there's hardly a blade of grass left in the county! 😂



  • Registered Users Posts: 2,015 ✭✭✭John.Icy


    EDIT: Thanks Danno. Found those definitions in the background there too. Though on this appendix it says Kilkenny provided C&F, which is pressure readings and that it was a climatological station already? So Scott didn't think there was a need (or ability) to provide 9am/9pm readings?


    From my limited grasp of lat/long - these values are junk without the seconds ('') right? 52° 39' & 7° 14' covers quite a lot of ground of the castle. Would we assume the seconds were rounded up or down to the nearest minute on a 0-29 and 30-59 bases or something?

    Alternatively if someone has the phone number for H.Carlton that would be great 😋

    In reality I assume someone like StratoQ has tried his darndest to locate the station within the castle grounds already and had no luck.




  • Registered Users, Registered Users 2 Posts: 13,666 ✭✭✭✭sryanbruen


    Stations of the second order were as follows, taken directly from the Met Office monthly weather report 1910.

    As the Met Office archive is a bit of a pain in the arse to navigate, I have made a Drive of all the reports a while ago here for anyone interested.



  • Registered Users Posts: 2,015 ✭✭✭John.Icy


    Thanks Sryan, what are resource. You're a top man.

    Now who's going to read through every single thing to look for any note or appendix clue that gives us a hint to where the station was! 😁

  • Registered Users Posts: 2,015 ✭✭✭John.Icy


    Report of the Meteorological Council 1884/1886. Some clues.

    1886:

    Seems generally well exposed if not close to trees from one angle. Not too much issue with that if PP is all good to Mr.Thorne?

    This is the first mention in 1884 below. Sorry I got the years mixed up as the eBook had two reports in one and I didn't cop. To note Mr. Scott said he hoped Kilkenny would become a 2nd order...rather far from his remarks in 1890.

    Further EDITS:

    1896 (?), our Mr. Carlton is very carefully in Kilkenny measuring the weather.

    1897; site was moved to a considerably better location compared to the previous. But the 1887 location was still considered well exposed bar one side no I don't think it's enough to be rubbishing the reading.

    Excellent work - so it seems Kilkenny didn't have the extra instrumentation to make it a Second Order station which from what I can make out is the wet bulb and wind speed and direction along with a more detailed report on cloud. So, climatological station is a step between second and third order using these older definitions.

    At this south Laois climatological station, I observe once daily and note the following:

    • Current air temperature at 9am UTC (10am during Summer time)
    • Current wetbulb at 9am
    • Maximum air over previous 24hrs
    • Minimum air over previous 24hrs
    • Rainfall amount from previous 24hrs
    • Current 5cm soil temperature
    • Current 10cm soil temperature
    • Current 20cm soil temperature
    • Grass minimum over previous 24hrs (basically an air min thermometer on pegs a half inch above grass tips)
    • Current state of ground - i.e. dry, wet, damp, glaze, frozen, snow, etc...
    • Snow depths
    • Current cloud cover in Octas 1/8.......8/8

    So, quite a bit to observe each day and alot more now than they did there in 1887! In addition I supply the dominant wind direction of the previous 24hrs and note any gales - but stress that this data on wind is from the Davis which is at standard 10m. I don't really know if they use that data at all though! :D

    Some other climate stations observe sunshine and deeper soil temperatures also.

    Contacted StratoQ earlier who thinks the station was located near where the current playground is. Back then it was a bowling lawn:

    Using StratoQ's location would put it in the yellow circle, give or take. You mentioned above a report with concerns about a tree to the north and this would probably place it closer to the red circle.

    That puts it ~142m away from the Castle itself and over 100m away from the southern wall of the castle. So, as you say - exposure wasn't really very much an issue at all with the exception of a tree north of there.



  • Registered Users Posts: 2,015 ✭✭✭John.Icy


    Had a bit more time and checked all other reports between the station beginning plus prior to moving it in 1897 and nothing else giving there. Station was either all good (dodgy rain gauge for a bit) or else the site was not visited.

    Red dot could be a good shot Danno, it fits the long/lat. Below is a guide to those coordinates of interest as per these reports. It does extend a bit beyond the top of the box but for obvious reasons this wouldn't be where the site is (outside the castle grounds). Now this would be assuming the reporting was very exact but see no reason why it wouldn't.

    Since we are only dealing with a ~10 year period not much hope of finding anything in the back of an image! 😁

    'Moved to the lawn' would imply it began much closer to the castle originally and on the concrete surface. So a move to where StratoQ thinks seems very plausible. But if 'on the north' just means to the north of the station from where Scott was standing when he noted the trees rather than compass north maybe?

    All in all yes, seems like we have no issue with the instrumentation and also no damning issue with exposure (or at worst, slight issue on one side but considered good nonetheless). Below is a response by Mr. Kilkenny weather himself:

    ^^ There are PHOTOS of the station??? Would solve all of the above whoever has them?

    Last thing on it that's interesting is in the radio interview the mention of the rounding of the fahrenheit reading, so the Kilkenny temp may have been a little lower but even up to ~33.6c at a quick conversion.

    Why does this Kilkenny record come up every single summer?

    Bottom line is that this record is officially recognised by Met Eireann. People can speculate and cast doubt about it all they want, but who cares. They have little to be worrying about to be honest.

    The OSI 6-inch maps show Kilkenny Castle as it was back around that time. The first edition is 1839-40 and the last edition is 1899-1902. No real change in layout between the two.

    Interesting interview, thanks for sharing.

    Would be very nice to see the photos as it would give better clues to the location in the castle grounds.

    From: https://www.thejournal.ie/europe-ireland-heatwave-climate-change-impact-5821014-Jul2022/

    Peter Thorne, climatologist and professor at Maynooth University, told The Journal that Ireland will also see the effects of climate change worsen in the near future.

    “33.1°C has been reliably measured in Dublin. Regardless of whether it’s a national record, it’s the warmest that’s been reliably measured in Dublin. If you look more broadly across France, the UK, parts of Germany as well as Ireland, so many stations are breaking monthly or all-time records. This is not remotely normal,” he said.

    “This is entirely consistent with what we’ve observed to date and what we expect to happen as climate change continues its course. I mean even that 33.3°C, if Met Éireann maintain that it must be the record, that’s going to break sooner rather than later. It’s just a matter of time and where it would be broken.”

    “Maybe not next summer, maybe not the summer after that, but in a summer within the next decade or two… we will have heat extremes that are probably far worse in either duration, extent or magnitude than we are seeing right now, which is very much a flash, two or three-day heatwave.

    It’s only a matter of time until we see something much worse unless we resolve to stop our heat-trapping gases emissions.

    Unusual phrasing used when speaking to the B-Rated Journal.ie and he's wrong too - 33.0c is the record in Dublin, not 33.1c.

    I gather from Twitter and Kilkenny Weathers page that Met Eireann have the photo of the site;

    So next up would be; when was the photo taken and was it in the initial 10 year period when the record was set (and before the site moved again) & pretty please can we all see the photos.

    There is another map of killkenny from 1871. Cant read what it says as looking on phone but there is something written beside a piont circled in red

    The air in the atmosphere is no warmer than its ever been...the only thing that is changing is the temperatures being recorded on the surface...and they are only going up because of all man made activity cities..buildings..roads etc....

    Was this actually 92’F ?

    You kinda get the feeling that the moment the Kilkenny 1887 reading is surpassed, that it'll be forgotten very very quickly by the powers that be. As it stands at the moment, it's an annoying thorn in the side, an inconvenient record.

    I think so, 33.3 C is the conversion of 92F, so it may have been anywhere from 33.1 to 33.6 C as we don't have the decimal Fahr value that was rounded to 92F.

    After reading this discussion, I have more confidence in it, obviously the castle itself was far enough removed that it played no role, and the site appears to be quite well ventilated. It is at least as reliable a location as Phoenix Park and better than tarmac city I mean Shannon.

    I had a look at historical weather maps, the setup was generally easterly with high pressure not far removed, implying this was a day of sunshine and light winds. While there are no obvious signs of spectacular warmth, you could easily imagine a reading this high inland with a bit of a downsloping effect to assist.

    Its ~45 miles from Cahore Point to Kilkenny City as the crow flies and that takes up right over Mount Leinster at ~2,625ft (~800m) which would be an almost east airflow
