Low temperatures will end a month of “extreme” weather in the UK, which has included two named storms, a heatwave, and the hottest August day recorded in 17 years.
The Met Office said that although the bank holiday has been “unseasonably cool”, the low temperatures are not expected to break any records.
The chilly spell is in stark contrast to last year’s late August Bank Holiday Monday which was the hottest on record, when the mercury hit 33.2C at Heathrow airport.
Alex Burkill, meteorologist at the Met Office, said that the variety of hot, cold and windy weather would likely not be reflected in the monthly averages.
“We’ve not broken any records with how cold it’s got,” he said.
“Daytime temperatures (on Sunday) did struggle, but the lowest maximum temperature was 12.5C and the record is 9.1C, so we’re quite far off that.
“Monday daytime temperatures will struggle again, probably only just about getting into double figures in some places, but i’d be surprised if we broke any records.
“It has been quite extreme at times, we’ve had some very hot weather and then the two storms towards the end of the month,” he said.
“Even this bank holiday has been unseasonably cool, it’s not that often that we get temperatures around freezing in August.
“(The weather) has brought everything this month and that’s not really going to be captured in the monthly averages.
“They’re not going to show the extremes that we’ve had.”
Last week, the UK was battered by Storm Francis, which saw gusts of 81mph hit The Needles near the Isle of Wight, just days after Storm Ellen had struck.
The Met said it was “unseasonable” to have two named storms occur in August within such a short period.
“It’s not that usual for us to get these types of storms in August, in fact it’s the first time we’ve ever had a named storm in August,” said Mr Burkill.
“To then have another one week after the other is even more extreme.”
The storms followed a spell of blistering heat, which included a high of 36.4C (97.3F) at Heathrow and Kew Gardens – the hottest August day recorded in 17 years.
