Weather Summary January 2019 (3rd February)

High pressure dominated the weather for the first half of January. This brought a good deal of dry weather with variable amounts of cloud often associated with a series of weak weather fronts which moved around the High and then south across the district. There was a transition period between the 15th and 17th when the high pressure eased away allowing northwest than west winds to develop heralding a rather unsettled period as milder air and rain spread from the west. Later in the month colder air returned across the area preceding a period of rain which turned to snow on the afternoon and evening of the 31st. E to NE winds increased and allowed cold air to undercut the milder air which was displaced to the south. Although some snow had fallen on the hills above Teignmouth and Dawlish on the 30th the evening of the 31st saw the first significant snow of the winter.

In terms of statistics:
The average temperature for January was around 6 Celsius, that’s close to the long term average. Most places had multiple mornings with a ground frost, and air frost occurred on between 8 and 12 nights inland and around 2 to 4 nights near the Teign estuary. The long term average number of frost at the Teignmouth Den weather site is 4 nights in January. The mildest day was on the 13th with maximum temperatures around 13 Celsius and the coldest morning was on the 31st when temperatures fell to between minus 2 and minus 4 Celsius in most places although Netherton area managed a low of minus 6 Celsius.
It was a dry month with around 18 days (+/-3) with no measurable rain and rainfall totals ranged from 35 to 55mm which is about half the normal January rainfall. There were around 10 days when 1 mm or more of rain was recorded, the average being 13 days. The wettest day, with around 11 mm, for most of the area was the 31st although the 18th and 26th were also contenders.
Snow or sleet fell on two days 30 and 31st and accumulated on 1 day (31st) which is average for January. At Dawlish 3cm of snow was recorded amounting to 3mm of water equivalent rainfall.
Sunshine was slightly below average, the total recorded at Teignmouth was 59 hours which was about 6 hours below average.


In summary, January 2019 was a good bit drier than normal but with near average temperatures, air frost and snowfall. Ground frosts were probably a little more frequent than average. Sunshine was slightly below average.
