Brits will be basking in the sun today as the scorching '30C' melts the UK today.
The mercury is expected to soar to the high-20s and could even reach 30C in some areas of the country and make it hotter than Ibiza.
The sizzling temperatures could also bring a new 'hottest day of the year' so far if it reaches dizzying heights.
It comes as England is set to face Croatia at Wembley as they launch their Euro 2020 campaign.
High pressure sweeping in from the south will make areas of the UK warmer than bustling tourist destinations like Ibiza and Mykonos and even California in the US.
Northern areas of the country are expected to be slightly milder with 26C predicted in Aberdeen, Scotland.
Showers could also cool the north.
Forecaster Alex Burkill said: "The picture this weekend looks very warm and sunny for much of the country.
"There will be some showers in parts of Northern Ireland and Scotland, and some cloud in the north-west though it will remain very warm in the sunshine."
The top temperature recorded on Saturday was 24.8C at Kew Gardens in South West London.
But today (Sunday) is predicted to be even hotter and temperature possibly reaching or surpassing 30C in the south east.
This scorcher has never been seen on June 13, according to records.
Mr Burkill added: "Sunday is likely to be the hottest day of the weekend, with temperatures reaching 29C (84.2F) in London and the South East, while the bulk of the country will be dry with lots of sunshine.
"This heat is likely to be widespread in the mid-20s which is above the average for this time of year."
Although he said it is "unlikely" it'll reach 30C he added it "shouldn't be ruled out."
As Brits head to the pubs and beer gardens to watch England at the Euros, fans are warned that UV levels will be "high or very high" and the grass pollen count could cause issues for hay fever sufferers.

The Met Office issued a warning over the pollen count, which is likely to leave those affected with sore and itchy eyes and runny noses.
Met Office forecaster Nicola Maxey said: "Pollen rates for the whole of England and Wales are very high for the next five days.
"It's going to be quite uncomfortable for those who get it really badly.
"The UV levels are also very high over the weekend which means people could burn quite in a short space of time without realising."
