Weather Report – January 2017

In Plymtree although January was not as dry as December there was still a good deal of dry weather with more than half the total rainfall for the month being recorded in the last 5 days. The total rainfall I measured for the month was 79.6mm. The average (1981-2010) at Dunkeswell Airfield is 112.5mm. This means that we received 71% of the Dunkeswell average. The wettest day of January was the 27th with 15.5mm. There were 12 rain days (rainfall ≥ 1mm), which compares to an average of 15.6 days for Dunkeswell, and 17 days with no measurable rainfall. Fog was quite persistent on the 23rd and 24th and account for the small rainfall figures shown on these days (0.3mm on each day). The highest temperature I recorded during January was 12.1°C on the 7th. On both the 21st and 26th the daytime temperature did not rise above 1.8°C, although ironically the maximum temperature (0900-0900GMT) on both these days occurred overnight (4.4 and 4.6°C respectively). The lowest temperature, -8.1°C was recorded on the 3rd. Because there was a good deal of dry settled weather with high pressure in charge, bringing cold frosty weather, air frosts were recorded on nearly half the nights during the month. The strongest wind during January occurred during the early hours of the 2nd when a gust of 34.2mph was recorded by Pete Draper at Normans Green. The strongest wind I recorded was a gust of 25.3mph on the 13th.

[The difference arises because my wind speed is 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].
