The coldest May night since 1996 was felt in many parts of the UK on Tuesday, some of which have seen snowfall, said BBC forecasters.
The night time UK average is normally 4-7C in late May.
But -6C was recorded in the Highlands of Scotland, -3.1C in Oxfordshire, -4.3C in Wales, -5.3C in Cumbria -3.9C in East Anglia and 0C in London.
Forecasters said it was unusually late in May to see frosts, and that daytime temperatures had peaked at just 13C.
Daytime temperatures would normally be expected to reach 16C at this time of year.
But forecasters added that temperatures were expected to creep back up to 16 or 17C through the weekend.
