Summer will not start until the end of the month, the Met Office has warned.
Britain basked in temperatures of up to 24C at the weekend raising hopes sunshine was here to stay.
But forecasters poured cold water on hopes that summer is fully here.

They warned it was only `a taste’ as wet, windy and cooler weather is on the way over the coming weeks.
Brits will have to wait until the last week of June – just before polling day – for a prolonged period of settled sun.
But when it arrives it should be a sizzler.
Long-range forecasts show – based on climate data for June, July and August from 1991 to 2020 – the UK is on course to exceed the average temperature of 24C in the south of England.
This would mean a sustained period of high-20s in the south and low-20s in the north where averages are lower.
Met Office forecaster Marco Petagna said: “It’s been a taste of summer for the first couple of days.
“But for the week ahead and much of June it’s looking more mixed again.
“But there are signs that towards the end of June we could see something more settled, warmer and drier.’’
He said for the three months of June, July and August temperatures are “likely to be above average overall so there’s a chance we’ll see some hot spells at times”.
“The temperature signal is pretty good. It’s expected to be warmer than average overall,’’ he added.
Records are unlikely to be smashed though as it would take something `exceptional’ to beat the 40.3C heatwave that became Britain’s hottest ever day in July 2022.
Though warm rain could hit, July is not expected to be a washout like last year.
With meteorological summer officially beginning this weekend the highest temperatures recorded on Sunday were 24C at Pershore, Worcs, and 23.9C in Usk and Cardiff in South Wales.
The hottest UK temperature of the year so far is 27.5C in Chertsey, Surrey, on May 12.
