Data comes from Met Éireann.
Do you have a link for where these were found? I am very surprised at the 1974 figure of 28.0C on 25th August; the highest I was aware of in Ireland was 25.7C at Belmullet on June 21st.

As I mention in the post, I got the figure from a file a poster shared with me (I think it was via PM rather than post in this thread). Unfortunately, that was a while ago now and I deleted all my PMs.

However, good thing you brought it up because looks to me that it's an error on Met Éireann's behalf in their historical database on met.ie. The pattern on 25th August 1974 looks in no way conducive to such a max temperature at Thurles. The 28.0C figure on met.ie database for the station is also sandwiched between 19.0C on 24th and 16.6C on the 26th. Another mistake to bring up with the Met I guess.

Nice catch!

1993: 28.6°C at Cork (Clover Hill) on June 27th
1987: 29.0°C at Waterford Airport on July 5th

Those seem like they might be rather high too! The highest I was aware of in 1993 was 25.0°C at Ballyshannon on 28th June and in 1987 26.6°C at Dublin Airport on 16th August.

The highest temperature of the 20th century was 32.5°C at Boora on 29 June 1976, but it is said that the 32.0°C at Shannon Airport on 28 June 2018 is the highest on record at a synoptic station. I am in UK so am unfamiliar with some terms used. What is the difference between a synoptic station and stations like Boora?

Not so sure on the 1987 figure because it was a warm day in southeast Ireland. Those figures you are aware of are probably from the monthly weather bulletins which back in that day *mostly* showed only synoptic stations. Stations like Boora were climate stations. Synoptic stations were stations that collected data at "synoptic times" like 0000, 0600, 1200 and 1800 along with others like 0300, 0900 etc. Climate stations tend to be volunteered. Before UKMO WOW had climate stations' data automatically updating, we only had synoptic stations' data immediately. For climate stations, we had to wait at least a few months after for the data to come into the online database.

The synoptic stations are on the monthly and daily data section of met.ie (and yesterday's weather/current observations pages). There are currently 25 in operation.

They were from the weather reports. I remember the August 1990 edition mentioning that 31.0C was recorded at Glasnevin and 30.6C at Phoenix Park, the highest at a "weather station" was 29.5C at Casement Aerodrome.

Is the database still available on the met Eireann website?

The link below. Some data are missing for whatever reason on their new site's historical database so you'll need to check archive.met.ie too (second one).

Apparently Mullingar recorded 28.0°C in June 1970 but couldn't find the date though, possibly 10th?

1995: 31.5°C at Carlow (Oak Park) on August 2nd
1985: 25.6°C at Casement on July 4th

Do you have a list of lowest yearly minima?

I used to have a database with all the historical station data (just wrote a fairly simple script that cycled through and downloaded the csv for each station) but my old laptop packed it in so I lost it all. Might give it another go as it was interesting to play around with the data

I have had a look at some of the historical data for Valentia and their highest temperature of 1954 was less than 70°F and was on 7th October!
Contrast this with 1955 when their highest ever temperature of 29.8°C was reached on 24th August.
The temperature measurement unit switched from Fahrenheit to Celsius in 1961 for the UK (although the majority of stations probably used Fahrenheit until about 1970), when did Ireland switch units?

I also did 1910-1940 in case you missed that whilst scrolling through the thread. These have been converted to Celsius from Fahrenheit however.

Last posted an update to the Irish heatwaves record I compiled (Irish heatwave is defined as 5 consecutive days with a max temperature of 25.0C or more at a station according to Met Éireann) two years ago. I have only found two more heatwaves since that update, those of July 1921 and July 1934 that I have done historical posts on.

I have attached the file with the record including those two added to it. Whilst doing it originally with the digitised data was tedious enough, looking through old UK Met Office daily weather reports was a different kettle of fish of tediousness and then having to convert Fahrenheit values into Celsius too.

I believe you try very hard but simply I do not believe those numbers, highs or lows.

Temperatures over 35c here in the midwest in the summer 18 without a doubt. Lahinch on June 31st according to the public temp gauge display read 38c. I was there and it was the hottest place I had been since I was in Seville in August a few years ago.

Cavan recorded -19c in the that very cold 3 week snap we had a decade ago. I recorded -16 here myself in the suburbs of Limerick in that cold spell. "Lies, damned lies, and statistics"

I don't think those lists give an accurate reflection or are overall definitive figures to suggest with any certainty that they are correct and truly accepted. I don't think they stand up. There simply are not enough weather stations.

Not surprised to see the 1960s not feature in that list, but even the cool summer of 1972 appears 11 times whereas 2003 only appears 10 times. I would be interested to find the highest maxima and lowest minima from 1941 to 1960 somewhere. 1947 and 1955 may feature more with other stations. I noticed 1959 appears once and was in September, the highest I aware of for Ireland in 1959 is 26.7C at Valentia on September 12th. Predictably most are in June, July and August but there are two entries for May 2012 and one for September 1991. I am surprised that August 1975 or August 1990 do not feature considering that 30C was recorded.

Regarding 1972, I find it bizarre that Killarney (Muckross Hse.) had a maximum of 25.7C but Killarney (St. Finans Hosp.) had a maximum of 28.7C, a 3C difference.

As I expected, 1976 and 1995 dominate the list but I'm surprised how easily 1995 beat 1976. 1995 appears 102 times compared to 62 for 1976. Also appering frquently is 2013 with 33 entries, 1983 with 31, 2006 with 29, 2018 with 28 and 1989 with 24.

According to met Eireann historical data -8.8c was recorded at Ballybrittas on 2nd April 1969. I assume this is incorrect.
