November 2017 can be summed up as a little cooler than average, a little wetter than average and a little sunnier than average but the devil is in the detail so here goes.
Temperatures were up and down like a yo-yo through the month, not that uncommon given that the nights are longer and late Autumn frosts get deeper as the longer nights develop. The lowest temperature was -3.1C on a frosty morning of the 13th but there were quite a few other air frosts amounting to 59.6hrs when air temperatures were at or below freezing. At the other end of the scale there were some mild days with the highest temperature of 14.8C occurring right back on the 1st. It was the nights though that helped the monthly mean temperature to fall nearly a degree below the long term mean.
Rainfall was a frequent event too as depressions passed by from off the Atlantic from time to time. One such depression deposited 17.2mm of rain on the 3rd making it the wettest day through the month although the 7th, 11th and 26th also recorded rainfall above 10mm. The total for the month was 109mm.
Winds were not a big feature of the month although there were a couple of windy days, none moreso than the 22nd when a gust of 45mph was recorded over the hills above the village and even 27mph down here in the valley.
Sunshine was a bonus this month with a total of 70 hours through the month not bad given that daylight hours are limited. The sunniest day was the 8th with 6hrs and 48mins of sunshine so the month ended with around 15hours of sunshine above the long term mean.
Fogs were not that common but there were a few foggy periods right at the start of the month when 16hrs and 15mins of dense fog was observed on the 2nd and 3rd.
Air frosts were common with a total of 59.6hrs of air frost here in the valley but rather less over the hills around. There was no phenomenon unusual to the area this month so my appraisal right at the start of this report is a good summariation of how this November has been
