November 2011 Lampeter, Ceredigion, Wales

Exceptionally mild, below average rainfall

Very little in the way of cold this month, and although unsettled at times, Ceredigion was spared the worst of the rain.

1st – 4th: A deep low close to Ireland made for a very mild unsettled start to the month with rain or showers, heavy at times.

5th- 7th: Cooler, dry with some sunshine and overnight frost and fog. Quite a severe frost on the 7th with a low of -5.5c which put paid to many of the late flowers and out of season budding. A rather cold maximum of just 6.8c on the 7th.

8th- 11th: Unsettled and very mild. Low pressure over the Atlantic brought up more Tropical Maritime air from the south. Rain at times, some heavy. It was often cloudy, although with a sunny interlude on the 10th.

12th and 13th: Exceptionally mild and dry with plenty of sunshine. 17c on the latter was the highest this late in Autumn for several decades.

14th- 30th: Mild to very mild and mixed. Sunny spells and also some rain at times. Ground frost occasionally by night and a slight air frost on the 23rd. The final week of the month was often windy with gale force gusts at times. The 11.6c minimum 29th in stark contrast to the run of sub -10c nights we were in this time last year! Still some budding and flowering.

After the warmest and driest October I have ever recorded (since starting in 2003), November has followed suit and repeated the trick! Of greater significance (if that's possible) is that the mean is 4.49c higher than last November!

Average max = 11.92c (Highest = 14.9c on 3 Nov)

Average min = 8.21c (Lowest = -0.5c on 28 Nov)

Mean = 10.06c

Dry days = 11

Rain days = 19 (10 days with 1mm or less!)

Rainfall = 59mm

Looking at the autumn temperatures then it is also the warmest I've recorded beating the previous in 2006; it showed 12.8C this year it is 13.1C

November 2011 stats for Cleadon:

Mean max 11.9C

Mean min 6.9C

Mean temp 9.4C

Highest max 15.1C on the 3rd

Lowest max 8.7C on the 20th

Highest min 11.3C on the 4th

Lowest min -1.3C on the 7th

Air frosts: 1

No days of sleet, snow, hail or thunder

3 mornings with fog at 0900

Precipitation 15mm

Days >= 1mm: 7

This made November 2011 the warmest November since I began recording, beating November 1994 by 0.4C (it will be interesting to see whether nearby Durham also breaks its all-time November record but I think it is strongly odds-on). Unlike at Doncaster, the autumn's mean temperature at Cleadon fell fractionally short of the 2006 value. It was also the driest November since 2004, making it part of an exceptionally dry year (although I'm not confident that my rain gauge has picked up all of the year's rain). The first half was dry and very dull, with persistent south-easterly winds and just a couple of bright days, with one intervening frosty night (the 6th/7th). Although the second half continued exceptionally warm, in contrast it was generally sunny, with plenty of hazy sunshine shortly after midmonth and then some bright blustery "westerly" days near the end.

The warmest November since 1994 here and the second mildest on a record back to 1963. It was consistently mild by day and night without any records being broken although the the lowest max' of 7.0c on the 20th was the highest on record.

It was the 5th driest November in the last 35 years and the driest since 2004. The maximum daily fall of 14.5mm was the lowest on record for the month. This continues what has been a very dry year with the rainfall total of 691.1mm up to Nov' 30th being the lowest for the period since 1975.

Sunshine was well below average, the lowest total since 2002, and it was also the foggiest November since the same year. There were approximately 205 hours of fog during the month placing it in the top ten foggiest months on record.

It was the calmest November since 1993 although things livened up at the very end of the month with two gales in the last 5 days.

The second warmest November in 31 years and cooler than 1994 by just 0.3°C. The average maxima for the month was the highest, beating even 1994. The low max of 7.5°C on the 20th was the highest since 1997 and the minimum on the night of the 3rd the highest since 1996. The lowest minima of the month of 3.6°C was equal to the record high set in 2002. As well as being almost the warmest, it was the driest November Ive ever recorded, easily beating the driest of the last decade of 34.3mm set in 2004. Only three days saw rainfall of more than 1.0mm and 1.6mm of the monthly total was due to heavy dews. Despite being such a warm and dry month it was the dullest since 2004 and 2nd dullest of the last 10 years.

The first half of the month saw a persistent high to the east bringing winds from that direction. This gave a combination of generally mild and cloudy weather. Apart from the 4th when almost half of the month's rainfall total fell, it was generally dry except for short periods of drizzle and heavy dews overnight. Night temperatures were particularly mild with the lowest temperature in the first 15 days being 5.2°C. Daytime temperatures were generally very mild, but rather homogenous. The second half of the month then saw more in the way of sunshine and thick fog at 0900 on the 20th. It became rather windy in the final week, though rainfall amounts remained small.

Overall, a rather benign month, devoid of any real weather. It was warm enough to make the Autumn the second warmest in 31 years (0.2°C behind 2006) and the driest on record with just 66.8mm of rain, a mere 42% of average. Despite November's lack of sunshine, the Autumn was sunnier than average at 347 hours (111%), but only had the highest total since 2007.
