Weather Summary February 2020 (1st March 2020)

Low pressure and associated weather fronts bringing cloudy, wet and at times windy weather again dominated the weather patterns across SW England for much of the month. There was a brief interlude with High pressure on the 5th and 6th which allowed for two of only three completely dry February days. The High gave way to low pressure from the Atlantic and lead up to the first named storm of the month (Ciara 8th and 9th) bringing gales to many parts and the start of a very wet periodl. Winds remained mostly from a westerly point as further weather fronts and associated low pressure areas swept in from the Atlantic. Storm Dennis bought of gales and some very wet weather on the 15th and 16th – the old Vicarage in Dawlish was one casualty seeing the collapse of a Cobb wall during the storm. A weak ridge of higher pressure on the 21st brought the remaining completely dry day of the month before further depressions moved across the UK. The month ended with storm “Jorge” – named by the Met Service of Spain because of damaging winds were expected over NW Spain at the end of the month, although, conveniently the UK also had windy and wet weather.

Weather Summary January 2020 2nd February 2020

Low pressure once again dominated the weather pattern bringing wet and very mild weather for a good parts of January. There was a interlude with high pressure in the early part of the month and a more prolonged spell between the 18th and 24th. During this latter period the pressure rose to near record values of 1050mb and was associated with rather frosty nights. Most of the low pressure centres crossed over or to the north of the UK but during the 9th and 10th low pressure tracked east across SW England. Snow fell over some parts of Dartmoor briefly during the month but was absent from Dawlish and Teignmouth, although a few hail showers did occur.

In terms of statistics:
Recorded rainfall of between 90 and 130mm was near or slightly wetter than average, with inland areas seeing the higher totals. The wettest period was being the 13th to 16th when about a third of the months rain fell - the highest 24 hour rain total being between 15 and 25mm. Of the main Met Office weather stations in the SW most indicated slightly below average rain for the month.

There were around nine days with no measureable rain, although dew or melting frost accounted for around three days in some areas reducing the number of “dry” days to six (30 year average 11 days). The number of days with 1mm or more of rain recorded was between 15 and 18 (30 year average 13 days). There was between 3 to 5 days with 10mm or more (30 year average 3 or 4 days), and in a few inland hilly areas the 14th saw values of 20mm or more.

The temperature averaged out at around 8 Celsius, just over one degree above the 30 year average. Teignmouth Den recorded an average Maximum temperature of 10.5C (30 year average 9.4C) and average Minimum of 6C (30 year average 4C). The highest temperature recorded during the month was on the 14th or 30th of around 14 or 15 Celsius. Lowest temperature was recorded on the 20th during the high pressure period with lows ranging from minus 1.5 Celsius in Teignmouth to minus 4.6 Celsius in Netherton. Away from the immediate coast air frosts occurred on as many 5 or 6 nights but only two nights at Teignmouth Den, where frost was below the long term average of 4 nights.

70 hours of sunshine was recorded at Teignmouth which was slightly above the average of 65 hours. The electronically recorded values at Dawlish and Netherton indicated only 27 hours (Low priced sensors tends to under estimate in winter and over estimate in summer). Of the main Met Office weather stations in the SW, Culdrose reported above average sunshine and Yeovilton below average.


In summary, January was milder than average with near or slightly above average rainfall and slightly above average sunshine. Frost at Teignmouth was below average but in some inland parts frost was more frequent.
