Rainfall Report – December 2017

December continued the trend of the last 4 months with a high number of wet days. There were 20 wet days with rainfall totalling 94.5 mm (3¾ inches), slightly above the December average of 86 mm (3½ inches).

So, that’s it for another year. Rainfall for 2017 totalled 779 mm (30½ inches), 9% below the annual average of 854 mm (33½ inches)  Despite the below average rainfall, there were 178 wet days, which is the second highest number in the last 27 years and well above the annual average of 140. 103 of these wet days were in the second half of the year, and 72 days recorded just 2 mm or less. 2014 with 188 wet days is the highest number I have recorded, but that was a very wet year with 1063 mm (41¾ inches) of rainfall.

April was the only dry month during 2017 with just 13.5 mm (1/2 inch) and 5 wet days. The other 11 months were close to the average, which probably explains why it has been a good year for wellies.

Nothing to do with Rimpton, but you may be interested to know that the wettest single day during 2017 recorded in the UK was at Ennerdale in Cumbria on 15 May when 168 mm (6½ inches) of rain fell (source Met.Office). On that day Rimpton had 4 mm (1/8 inch).

That’s it for another year. Happy New Year to all my readers (I hope there are a few of you).
