    It’s fkin impossible plan any outdoor work this week/weekend
    Forecast seems to change every few hours
    Tomorrow and sat were promised dry up until latest update

    In terms of the Irish Mean Temperature (IMT), the 1st-5th June 2019 has had a mean temperature of only 11.8c which makes it the second coolest of the decade in comparison to the 1st-7th period of other Junes and behind only 1st-7th June 2015 which had an IMT of 10.6c.

    In terms of max temperature, the 1st-5th June 2019 has had a mean max temperature of only 15.2c which like mean temperature overall makes it the second coolest of the decade in comparison to the 1st-7th period of other Junes and again behind only 1st-7th June 2015 which had a mean max of 14.7c.

    Last but not least, in terms of min temperature, 1st-5th June 2019 has been rather unremarkable with a mean min temperature of 8.4c makes it lie nearly bang in the middle in comparison to the 1st-7th period of other Junes in the past decade since 2010. You might have guessed it already but 1st-7th June 2015 was the coldest for mean min temperature too with a mean min of only 6.6c - well below average!

    IMT temperature stats of each 1st-7th June period for the 2010s decade (1st-5th June for 2019).

    Year|Mean temp.|Mean max.|Mean min.
    2010|14.8|19.4|10.1
    2011|13.0|17.6|8.5
    2012|12.8|15.9|9.8
    2013|13.7|19.3|8.1
    2014|12.4|16.6|8.2
    2015|10.6|14.7|6.6
    2016|15.7|21.7|9.8
    2017|12.1|15.8|8.3
    2018|16.7|21.8|11.6
    2019|11.8|15.2|8.4


    Interesting how close 2016 and 2018 were in terms of mean max temperature although 2018 easily bet in the mean min department.

    2012 not as low in these stats as you may think but it had a rather low mean max temperature nevertheless though its mean min held up well which was more than likely due to all the cloud from the rain disallowing cold nights.

    If we were to look at rainfall totals, I'd say 2012 and 2017 would be the wettest followed by 2019.

    Acc to this - not sure how reliable - the average high temperatures in Dublin for May are 15 degrees

    https://www.holiday-weather.com/dublin/averages/

    So while 21 degrees may not be out of the ordinary in July, in fairness for May its way above average

    It’s above average but it’s not a scorching temperature by any stretch. That it doesn’t happen every day during the summer doesn’t change that. And even if we only had ten days that hit that temperature over the summer months, we’d still be experiencing it more frequently than every two weeks. Not that the regularity of it is the determinant in whether it’s a hot temperature or not.

    Have recent April, May, Junes been as bad?
    I know last year clouds the memory but this spring has been shocking....Bar Easter..

    It’s bad. A crude measure but the night before last, I had a hot water bottle in bed with me AND a blanket over the duvet. Absolutely unheard of me for even May, never mind June. Okay, that’s just one night BUT I’ve not taken the blanket off the bed yet except for two warmish nights. Usually, again, the blanket would be jettisoned in May and I’d just be using the duvet. And often in summer, it’d just be blanket, no duvet. So, it’s noticeably colder so far this summer. And I have a well-insulated apartment.

    MT's forecast for tomorrow is short (and not particularly sweet)..

    SATURDAY ... Variable cloud, showers, isolated thunderstorms. Moderate north to northwest winds. Highs near 15 C.

    Anyone care to add their own interpretation for Slane and Malahide, for the 100,000+ who'll be standing in a field tomorrow?

    Expect to get wet at some point during the day.

    Evening may be better/drier.

    First true blue sky in Meath in a long time. Lovely.
    Cool morning.


  • Registered Users, Registered Users 2 Posts: 48,254 ✭✭✭✭km79


    Fantastic morning in east Galway
    Even a bit of warmth in the sun


  • Registered Users, Registered Users 2 Posts: 12,780 ✭✭✭✭ninebeanrows


    There is still a fair amount of uncertainty on the track of the frontal rain today/tonight. Could well stay dry in the east yet (for the optimists!). Some fairly sharp showers likely next few days with the risk of some isolated thunderstorms.

    Probably because a lot of it is not in London
    Most of it is over sea still with the heavier bursts actually perilously close to the Wicklow and wexford coastline atm
    A lot of it is high based too,common enough in a Spanish French origin


  • Registered Users Posts: 1,628 ✭✭✭klaaaz


    That was a lovely summers morning with no wind in Dublin, Met.ie have changed their chart as having no rain today(rain was predicted originally) but their description of the forecast as well as the radar says it will rain! Contradiction :)

    That's an anomaly on their new website where they have graphics tables derived from a specific grid point for noon for example on harmonie meaning if theres marginal something nearby,its useless
    Human intervention in the written and broadcast forecast shows the correct forecast

    Am I right to assume looking at the models this morning that the warmer weather that appeared in FI yesterday for next week has been replaced by a low pressure that isn’t really going anywhere fast....

    Its currently raining here and has been for a couple of hours and temp is currently 12.1c


  • Closed Accounts Posts: 838 ✭✭✭The_Brood


    Was looking at weather around the world. There is pretty much no place on the planet that is colder than Ireland right now. A few, like Iceland, are similar temperature, maybe one or two degrees cooler. But in general, almost nowhere on the planet with a human population is it seriously colder than it is here.

    Yep during the day time in Australia, South America its still warmer or same temperature pretty much.

    After 10 days in Southern Spain the cold breeze was welcomed today.

    You picked the perfect time to go away. If there was ever a week to head off to the sun, this week was it. It's been awful here over the past 5 days, we've had fires lit every single day.

    Today has probably been the best day we've had all week, certainly felt the mildest. It was dry here up till a while ago but it's spitting rain yet again.

    Yesterday the ensembles were looking more promising for later next week, but this has changed alot today with a continuation of relatively cool and unsettled conditions lasting for at least another 7 to 10 days. It is set to get slightly milder next week, but temperatures look like they may not peak much past 16 or 17C at best.


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


    The morning certainly was nice in Dublin (pic attached of Clontarf) as was yesterday evening but back to reality since around midday with on and off spitting rain and overcast.

    latest GFS has rolled out, and things continue to slide away in the medium term, a definitely upgrade for cool and wet conditions later next week and into next weekend.

    Looks cool and unsettled with low pressure right over Cork.

    GFSOPEU12_156_1.png

    This is followed by a cool or cold plunge developing from the north-east with low pressure firmly in the driving seat.

    GFSOPEU12_186_1.png

    By Monday 17th June, there are signs of High pressure and warmer weather, but this is already pushed back 5 days since yesterday and so far away that my confidence of this is very low.

    GFSOPEU12_231_1.png

    This is all thanks to the extreme northern blocking, something which we would sell our souls for in winter, but the last thing we want to see during summer.

    Dull black sky here this evening. You’d guess late September maybe other than the bloom. So so disappointing. Longest days of the year and you can’t enjoy them really after work.


  • Registered Users, Registered Users 2 Posts: 14,478 ✭✭✭✭Thelonious Monk


    Ireland must get one of the worst "summers" on the planet if you like warmth and sunshine


  • Registered Users, Registered Users 2 Posts: 7,220 ✭✭✭pad199207

    This year feels like we are paying dearly for the fabulous one last year.

    Just thinking it’s 12 degrees outside now. What temperature was it in Ireland on Christmas Day last?

    Did the weather not just change though last year in the middle of July and summer was over then? It was only half a fabulous summer if I remember correctly. Can you imagine having nice weather from June to September, drool.


  • Registered Users, Registered Users 2 Posts: 24,457 ✭✭✭✭lawred2


    Don't know why we do this to ourselves every year..

    This is Ireland.

    Crap Summers are our norm.

    It was 15 or 16c a couple of Xmas's ago anyway, I remember how mild it was when I got out of bed hungover

    Reached 13C in parts, today was slightly warmer but the past few days have been colder at several locations. Finner was a full 3C warmer on Christmas Day than on Wednesday!


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


    We have warmer Christmas days than we get in summer with the sun blazing in the sky...it dosnt make sense...the extra strength in the sun makes no difference here in ireland :rolleyes:

    1983-84 maybe. 1989-90 were a good pair but 1990 was not that great in the west (exceptionally dull in August with Belmullet having 38% of its average August sunshine) and June 1990 was a very poor month everywhere. 1995-96 and 2013-14 were good too though Augusts in 1996 and especially 2014 were poorer.

    1975-76 were the only examples of back to back summers that I'd call truly fantastic and legendary.

    1995 from memory had a strong high pressure system in the Bay of Biscay feeding a glorious summer here, sun from late June to the end of September. Now we have a low pressure system from the same bay feeding us terrible weather for June! :)


  • Moderators, Science, Health & Environment Moderators Posts: 16,963 Mod ✭✭✭✭Gonzo


    outlook for the next 2 weeks looks very poor, not just for us but also for all of the UK, northern half of France as well as the low countries and western Scandinavia, part of northern Spain not doing great either, so this low pressure causing a very unseasonable June to quite a large portion of northern and western Europe.

    The south of Europe (except for Spain and Portugal) and eastern Europe are in store for a sizzling June.

    We need this northern blocking to weaken as we head towards July, the thing that worries me is such a setup can last a long time, so if we still have this pattern in July, then this could be very worrying signs for the summer. Fingers crossed this northern blocking weakens in the second half of this month.


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


    How good was 75-76 Sryan?

    Both summers featured a blocking area of high pressure that was of a frequent influence throughout them as shown by the comparison of their 500mb height anomaly reanalysis (from NOAA) below (the brighter the colours (green, yellow, orange, red), the more intense the high pressure was). You can see the centre of the anticyclone was almost over top of Ireland and in the case of 1976, the UK and Ireland had the most intense area of high pressure (compared to average) in the northern hemisphere.

    In some summers you tend to find a trough of low pressure stuck over top of Ireland whilst everywhere surrounding us has high pressure whether it's central and southern Europe or Greenland. However, 1976 was a rare opposite example to that (as was 1995) with omega blocking resulting in minimal cyclonic weather. 1975 wasn't quite as high pressure dominated but I mean, it's hardly one to be joked at like it was still very anticyclonic.

    7JMTMD5.png

    In fact, the UK & Ireland were nearly the warmest relative to average during Summer 1976 in the entire world according to NASA GISS. Anomalies from average typically between 1-2c above average but isolated locations could have been 2c above average or more. The only summer that has beaten 1976 for most places is Summer 1995. 1947, 1983, 2006 and 2018 were other comparable very warm summers but just not quite reaching the levels of 1976 and 1995.

    Uyxh3NN.png

    Both summers reached at least 30c at one point in their season whilst the actual max for 1975 was 31.5c on August 3rd (the joint highest August temperature on record for Ireland with 1995) and 1976 had 32.5c on June 29th (highest temperature for Ireland of the 20th century and second highest known on record). May 1975 was a record sunny May (holding the Irish May record of 289.6 hrs of sun).

    Data from Met Éireann.

    According to the Irish Rainfall series by Maynooth University, Summers 1976 and 1975 were the 7th and 8th driest summers on record for Ireland back to 1711 (as far as the series goes back) respectively with 136.9mm and 139.2mm of rain (again respectively). This compares with 131.0mm in Summer 1995 so not a huge difference with 1975 and 1976.

    More on Summer 1976 in my little slideshow I made last year and posted in the heatwave thread (shown below in case you missed).

    It was the year that ABBA was number one on the charts and Denis Howell was appointed Minister for Drought (but was followed by thunderstorms and a very wet Autumn).

    Enjoy!


    I have not come across a pair of summers that quite match the level of 1975-76. Both years reached at least 30c/31c in Ireland, both were exceptionally dry and both were very sunny.
