Comments on March 2016
Although March did not feel particularly mild, it was in fact well above average temperature, the 55th equal warmest in 168 years, and there were fewer ground frosts than usual (average = 16).

Rainfall was just a little above average but the long-period totals remain well above average.

There was less sunshine than usual but only two days with no recorded sunshine at all. Shallow soil temperatures are now above 6°C so spring growth should be starting!
