Summary for March 2018

A rather remarkable month after the relatively benign conditions through
the winter. The dullest, wettest and snowiest March in my record. In
fact it was the snowiest of any month and put December 2010 to shame.
The 2nd coldest March after 2013 (5.2C) and the first 'ice day' on the
1st since the 25th December 2010. A very high amount of sunless days and
no cloudless days!
