November 2021 had an unusual number of dry days and a correspondingly low rainfall total.

The month started unsettled due to a deep low pressure centre over Scotland. This centre filled and moved east as high pressure built in from the west. The high gave way temporarily allowing a weak cold front to move across the district overnight on the 6/7th. This was followed by milder SW winds between 8th and 10th during which time the highest temperatures of the month were recorded. Low pressure moved across the North of Britain with the associated fronts bringing some light rain to the district on the 11th and 12th. Pressure then remained fairly high right through to the 25th with only weak weather fronts crossing the district and producing some light rain on the 15th 16th 20th and 21st. After the 26th a deep area of low pressure over Fair Isle moved due south over the East of Scotland and England. This was the named storm Arwen which brought very cold northerly winds southwards along with storm force winds. In Dawlish and Teignmouth winds reached about 50mph in the early hours of the 27th but over the hills winds were much stronger and some trees and branches were brought down. The cold northerly winds fell light overnight producing a widespread frost on the mornings of the 28th and 29th before milder air and a little rain arrived on the 30th.

In terms of statistics (30 year averages 1981 to 2010):

Rainfall totals of 20 to 25mm were about a third or less of the average November rainfall and there were at least 15 dry days. There were several other days with only a small amount of rain. The wettest day of the month was the 26th and even then only around 7mm was recorded.

The temperature for the month averaged out close to the long-term value of 9 Celsius. The warmest day was on the 8th when temperatures rose to near 17 Celsius. The coldest morning was the 29th when many places had a frost. Lowest values ranged from just above zero near the coast to minus one Celsius inland but as low as minus two and half degrees in some rural valleys. The Netherton area for instance recorded 7 night frost compared to one in the Teignmouth and Dawlish area.

The sea temperature at the Dawlish Wave Buoy eased down to 11 Celsius from 15 Celsius at the start of the month.

Sunshine at around 70 hours was a little below average.
