March 2018

The continuous frost at the end of February continued for the first two days of March with about 3cm of fine snow on 1st and less on 2nd. The 1st was the coldest day, only reaching -1.7°C and falling to -5.4°C at night. The snow turned to rain on 3rd and the temperature shot up to 9.9°C, the following six days also reaching 9°C+ with nights free of frost. The weather during this period was unsettled, with showers and sunny periods.

Atlantic depressions moved in from 10th bringing milder weather, reaching 14.2°C, the maximum for the month. Temperatures in double figures were reached for the next week and significant rain fell on four days with a maximum of 8.0mm on 11th. The mildest night was 7.4°C on 15th.

More cold conditions originating in Arctic Northern Europe pushed their way west reaching us on 17th bringing more snow, not lying at first but about 3cm settled overnight of 18th/19th, with the temperature falling to -2.2°C. There were frosts on five nights. With sunny spells the daytime temperatures rose steadily from 0.2°C on 18th to 9.8°C on 21st, the snow thawing rapidly.

A series of depressions from the Atlantic returned on 22nd and continued until the end of the month, with rain on every day except one. This ranged from 0.2mm to 16.2mm, bringing the total for the month to 93.0mm over 23 days, which is 222% of my 25 year average. This was the wettest March since 2008 (93.9mm).

Daily maximum temperatures during the last ten days ranged from 7.0°C to 13.3°C and minima from 1.9°C to 6.0°C. Overall, the average temperature of 5.93°C was 0.94°C below my 30 year average.

In brief, March prolonged the winter, being both cold, with winds mainly from between north and east and very wet.
