Frost is a rare beast this year, even in the Wanstead Park frost hollow.
So far this year I’ve recorded just 82.5 hours where temperatures at 4ft (1.2m) were -0.1C or below. That’s just 37 per cent of what is recorded in an average year. And would suggest that frosts in December will be above average.
The lack of frost this year is even more remarkable given that the past seven years, especially the winters, have been so mild.
The fact that January 2017 looks the most remarkable month for frost reveals just how mild recent years have been.
