Here in Wembury we had the first air frost this winter last night.
Min -0.7°C.
Surprisingly this is very close to my average date for the first air frost which is 30 Nov.
in the record back to 1985.
Earliest first air frost 17th Oct. 1992.
Latest first air frost 5th Feb 2018,
and this was followed by the 'Beast from the East' at the end of Feb.
