High pressure dominated the first week of March with light easterly winds and mainly cloudy conditions, although the passage of a front on 3rd brought 7mm rain which was to prove the wettest day of the month. Daytime temperatures only reached single figures apart from 1st & 8th, which were both 10.3°C. Nights fell between 4.1°C down to 0.3°C on 6th with a ground frost followed by another on 9th.
The wind turned to westerly on 8th heralding a week of wetter weather with some rain recorded on six of the next seven days. However, the maximum daily total only ranged from 5.5mm on 12th down to 0.2mm on 15th. It was mainly showery with sunny periods between. The temperature generally just reached double figures with nights down to around five degrees.
By 16th high pressure took over again and remained high for the rest of the month except for brief incursions on 18th with 1.0mm rain falling and on 25th/26th with 3.4mm & 3.0mm. This brought the total rainfall to 30.7mm, just 73.2% of my 25-year average and making it the driest March since 2015.
With the anticyclone drifting slowly the light winds came from all quarters and days could be sunny or overcast or a mixture. The temperature mainly reached the low teens but went/sup to 17.9°C, on 29th, 21.5°C on 30th & 19.5°C on 31st. The average for the month was 1.1°C above my 30-year average.
March as a whole was a pleasantly mild, dry month with no heavy rain or air frosts and the bonus of a really springlike last few days.
