Thanks to Kevin Bradshaw (aka Mr. Data) for letting me know about this. May-July 2018 was a record breaker in terms of sunshine totals for NW England & N. Wales back to 1929. It recorded a total of 763.8 hrs which beats the previous record of 704.3 hrs in 1989.

This total also beats the sunniest Summer (June-August) on record for the areas which was 1976 with 681.5 hrs. Extraordinary stats I have to say.



Maximum temperatures are another standout for that period in NW England & N. Wales.

May 2018: 17.3°C 2nd warmest ever May

June 2018: 20.3°C 2nd warmest ever June

July 2018: 22.3°C 3rd warmest ever July

The maximum temperature for May to July 2018 average at just under 20.0°C. They were only 5 "summers" (again June to August) since 1929 warmer than this in terms of maximum temperatures.

Last but not least, rainfall totals are interesting, only summers 1976 and 1995 were drier than May to July 2018 for summers since 1929 in NW England & N. Wales.

A real historical period of weather May to July 2018 was for the regions named.

Data originally comes from the UK Met Office.

It says the wettest April day was in Cloone Lake (Leitrim) and the wettest September day was also in Cloone Lake, but in Kerry. Is that a typo?
I can confirm the wettest April day is also referring to Kerry. Leitrim is definitely a typo.

Only 408mm of rain from January to September at casement weather station in West dublin, incredibly dry year. Only 660mm fell all year at dublin airport last year. Dublin has been so dry in recent years

What a day it has been for stats here! Final stats of the day, the period May to September 2018 was the DRIEST on record for Dublin Airport back to 1942 with a total of only 155.7mm of rain beating the previous record of 181.8mm in 1995.

Haven't seen anyone saying this but the air pressure of 1041.3 hPa at Cork Airport and Sherkin Island on the 24th September is the joint highest pressure on record for the month of September. The other time air pressure this high was recorded was in Malin Head on the 11th of September 2009 (nice to see another similarity between 2018 and 2009 by the way). There's 2018 at it again

This coming Wednesday (10th October 2018) is reminding me a lot of the stunning day of Sunday 8 October 1995 which recorded blue skies for the vast majority of the UK with temperatures as high as 25c in London, even up to 21c in the Scottish highlands. Ireland tended to be cloudier but even here for a lot of places, there was plenty of sunny spells to be enjoyed.

Various maxima over the UK:

25.6c at Hawarden (equal highest temperature on record for the 8th October in the UK with the 8th October 1921 - see table below)
24.6c at Heathrow
24.1c at Cambridge
23.5c at Elmdon
23.0c at Ringway

In Ireland, places had their warmest October conditions on the 8th Oct 1995 since 1969 and 1959 including Malin Head recording 20.6c (since 1959) and Shannon Airport recording 21.1c (since 1969). Dublin (Merrion Square) recorded a maximum temperature of 22.5c whilst Dublin Airport had a maximum of 21.0c, the latter being the third highest October temperature on record at the station behind 21.2c on 2nd October 1971 and 21.1c on 1st October 1971. The southeast had nearly a full day's worth of blue skies. It certainly must have been a glorious Indian Summer day in October 1995.

The table below I compiled from the historical data shows the 28 June to 4 July 2018 period for Dublin Airport was the sunniest 7-day period on record at the station back to 1942. 2018 broke the 1995 record twice.

With all the talks on the prospects of an October 2018 cold snap courtesy of a northerly shot of Arctic air, let's take a brief trip down memory lane to 10 years ago.

10 years later.... the cold snap of late October 2008.

The last week of October 2008 delivered a northerly shot with air coming from the Arctic. This air was unusually cold by October standards in the UK and Ireland with the earliest snowfalls for some since October 2003 whilst the most widespread October snow in the south since 1880. Northern Ireland had its first October snow since 1934.

The 28/29 October 2008 were the coldest October days in the UK since 1974 with maximum temperatures widely over both countries below 10c throughout each of the days. Leuchars in Scotland had a maximum of only 4.5c on the 28th October beating its previous record low October max. of 4.7c on 30th October 1974 (records go back to 1957). Aberporth in Wales had a maximum of only 5.2c on the 29th October completely smashing its previous October record low of 7.4c on 22nd October 2003 (records go back to 1957). Both Wales and Northern Ireland had their lowest October maximums on record during this period with 2.2c on the 29th at Alwen (Wales) and 2.7c on the 28th at Killylane (Northern Ireland) respectively. The afternoon maximum at Dalwhinnie in the Highlands of Scotland on October 28th was 0.9c. Topcliffe in England recorded the lowest October minimum temperature in the UK since 2003 with -6.6c on the 29th.

In the Republic of Ireland, the lowest minimum temperature during the period was -3.0c at Casement Aerodrome, Co. Dublin on October 29th, its lowest October temperature since 1993 but for Ireland, this was only the lowest October minimum temperature since 2004 when -3.8c was recorded at Ballinamore, Co. Leitrim on October 20th.

Some notable low maxima recorded over Ireland during the period:

5.8c at Dublin Airport on the 28th and 6.3c on the 29th (both its lowest on record for October)
5.2c at Casement Aerodrome on the 28th and 6.4c on the 29th
5.6c at Phoenix Park on the 28th and 6.4c on the 29th
5.3c at Mullingar on the 28th
5.2c at Dunsany on the 28th and 6.4c on the 29th
5.5c at Derrygreenagh on the 28th
6.0c at Cork Airport on the 30th
6.3c at Moore Park on the 30th
6.4c at Oak Park on the 30th
5.8c at Slieve Bloom Mtns (Nealstown) on the 28th and 5.8c on the 30th
6.0c at Ardee (Boharnamoe) on the 28th
5.3c at Carrickmacross (Dunoge) on the 28th and 4.9c on the 29th

There was widespread lying snow on the night of the 28th/29th and the morning of the 29th October even as far south as London (see pictures below).

Berkshire, England.

The reanalysis chart for 28 October 2008 below shows the winds coming from a north to northeasterly direction with air originating from Arctic. There is a 1040mb area of high pressure in the Atlantic only helping to force this abnormal pattern of weather that occurred at the end of October 2008.

All time record is 1051.9mb at Valentia on 28th January 1905.

1043.9 hPa at Valentia (13Z today) is now the October record.

Station pressure was 1040.8 hPa, but still not as high as Sherkin Island's 1041.1 hPa this morning, which in itself must be a record for an Irish station.

Updating the Met temperature extreme tables for selected Irish stations which were produced at the end of 2010 and have not been updated since. Is there are any records you think I'm missing here? I've put 2018 in red.

Attached the PDF files to these tables too.

October 2018 was another drier than average month at Dublin Airport making the May-October 2018 period the driest such period on record here back to 1942 with a total of only 198.4mm of rain beating the previous record (again like May-September) of 219.8mm in 1995.



Will be editing the above post in a moment as I found more records (with aid from Kilkenny Weather) and thus edited the files.
