Unusually warm November


Temperatures are "exceptionally mild" for the time of year, with Scotland, Northern Ireland and Ireland all having the warmest November night on record. The temperature in Furnace near Newport never dropped below 15C on Friday and reached 18C during the day. Meteorologists say the mild weather is the result of a powerful jet stream bringing warm air up from the south as far as Cape Verdes. Average night-time temperatures in the British Isles at this time of year range between 4-6C.

It's certainly a bonus for millions of people who are concerned about heating bills, but is it a sign of a permanent shift in weather patterns, and how much is climate change playing a part?

Sea Temperatures off the coast of Ireland are almost at levels recorded during summertime, the head of forecasting at Met Éireann, Evelyn Cusack, has said. The unseasonably warm temperatures this month come after one of the wettest Octobers on record and the hottest summer in over 135 years. It's going to remain this warm right through to Monday. 

There are so many plants blooming and insects flying. It's just climate weirdness.

November Wx stats


The numbers are in for November and, despite the cold snap at the end of the month, the mean temperature for November was still the warmest of the past four years and a full degree above the long-term average (LTA) for the reference period 1981-2010. Rainfall turned out to be slightly higher than the LTA and soil temps quite a bit higher than prior years. 

Basically, it's all a bit unpredictable. No tropical cyclones formed in the Atlantic basin during November. However, Tropical Storm Wanda continued from the end of October through the first seven days of November.  Based on a 30-year climatology (1991-2020), a tropical storm forms in November every one to two years.

Overall, NOAA reports that the 2021 Atlantic hurricane season featured above-normal activity. Twenty-one named storms formed, of which seven became hurricanes and four became major hurricanes - category 3 or higher. Even though it seemed quiet in the Atlantic this year, it really wasn't - but it was definitely not as wild as last year.
