Weather Report – December 2014

In Plymtree the weather in December was very similar to the rest of the UK with milder, wetter spells, interspersed by drier brighter days but with frosty nights. Daily rainfall totals were generally much smaller than those in November. The total rainfall I measured for the month was 46.5mm. The average (1981-2010) at Dunkeswell Airfield is 121.2mm. This means that we received only 38% of the Dunkeswell average. The wettest day of the month was the 11th with 9.5mm and there were only 9 rain days (rainfall ≥ 1mm), which compares to an average of 14.9 days for Dunkeswell. My total rainfall for 2014 was 1199.9mm, which compares to an average of 1065.3mm for Dunkeswell or 113%. Again as with the rest of the UK a large contribution to the high annual rainfall total came from very wet weather in January, February, May, August and November. The highest daily rainfall total was recorded on the 18th September when 48.5mm fell during a thunderstorm. The highest temperature recorded during December was 12.7°C on the 18th. The lowest temperature, -8.5°C, was recorded on the 29th when the temperature didn’t rise during the day above 0.6°C and frost remained in the shade all day as it also did on the 13th and the 30th. Frosts occurred on 16 days during the month. This was also the lowest temperature of 2014 whilst the highest temperature of 30.2°C was recorded on the 26th July. The strongest wind during December occurred on Boxing Day evening, the 26th when a gust of 54.8mph was recorded by Pete Draper at Normans Green. My strongest gust was 29.1mph, also on the 26th. The strongest wind recorded by Pete during 2014 was during the evening of the 14th February when a gust of 62.4mph occurred.

[The difference caused by my wind speed being measured at a height of about 6' in the shelter of my back garden and Pete’s on the roof of his house and exposed to the elements].
