November weather summary

Mild, wet and windy weather during the first half of November was followed by a spell of drier but colder conditions, while the last few days of the month were extremely cold with widespread snowfall.

At most stations it was the coldest November since 1985, due largely to exceptionally low temperatures between the 28th and 30th. Air temperatures fell below -6°C in many places on the 28th and 29th, while both Dublin Airport and Casement Aerodrome recorded their lowest November values on record on the 28th; this was also the coldest November day on record at the same stations, with maximum values not rising above -1°C. In total, between 10 and 14 days with air frost were recorded at eastern and midland stations during the month, around twice the normal number for November.

The very cold period at the end of the month produced widespread wintry showers, but the heaviest falls of rain were recorded earlier in the month, associated with deep Atlantic depressions close to Ireland. Monthly rainfall totals were above normal except in the south. Heaviest daily falls were on the 7th/8th and 16th/17th, particularly in western areas, where localised flooding resulted. There were between 14 and 22 wetdays during the month at most stations (days with 1mm or more rainfall), a little higher than normal for November, while 26 wetdays were recorded at Belmullet.

Despite a very dull start to the month, sunshine totals were well above normal everywhere and it was the sunniest November in over 50 years of record at Belmullet.
