February 2019

The cold spell at the end of January continued into February, with more heavy snow in the middle of the day amounting to 6.6mm rain equivalent. The temperature only reached 1.5°C, proved to be the coldest day of February. The following two days remained cold, having fallen to -2.3°C and -5.7°C at dawn, the only air frosts in the month.

A change of wind direction from northerly to southerly on 3rd brought 6.2mm rain overnight and the temperature rose to 10.2°C. This was the beginning of an unsettled period of a week, with some rain on each day. The heaviest was 9.0mm on 8th and the total was 29.3mm. Temperatures ranged from 6.9°C to 11.5°C and nights from 2.3°C to 6.4°C.

High pressure moved in from the east on 11th bringing ground frosts with foggy mornings followed by sunny spells. Temperatures were in double figures, reaching 14.0°C on 15th.

A brief incursion from an Atlantic depression reached us from the west on 17th/18th bringing 2.0mm rain and milder nights.

The anticyclone over north-eastern Europe then resumed its influence bringing mild, dry air from the Mediterranean, the temperature gradually increasing from low teens up to a maximum of 17.°C7 on 26th. From 11th the nights ranged from 0.9 on 12th and 1.0 on 25th to a maximum of 7.7°C on 20th and 7.5 on 21st. There was early fog on 22nd/23rd and ground frosts from 24th-27th.

The 28th brought 2.0mm rain, making the total for the month 33.9mm just 73.8% of my 25-year average and 131.1mm (74.3%) for the winter months of December, January and February.

In summary, after a brief cold start, February turned mild and wet until 10th. The rest of the month was mild and dry, with plenty of sun, though with foggy mornings between 22nd and 24th, and slight ground frosts from 24th-27th. The average temperature was 7.16°C, 2.47°C above my 30-year average and the highest since 7.41°C in 1990.
