Brits travelling hundreds of miles to soak up the sunshine on the coast have sparked fears of a second coronavirus wave.
The glorious weather continues for most of the UK today after yesterday was recorded as the warmest day of the year so far.
The mercury climbed to 27.8C (82F) near Heathrow Airport on Wednesday, as sunbathers across England enjoyed new found-freedom following the easing of lockdown restrictions.
London's St James's Park recorded a high of 26.2C (79F) on Tuesday - beating 2020's previous top of 26C (78.8F) set last month.
But the good weather is clearly testing the nation's resolve when it comes to sticking to social distancing measures.
Some authorities said "valuable resources" were being used to police traffic and people jumped in the cars and headed to the coast or beauty spots.

Officers in Ilfracombe and Braunton said they had identified vehicles from "all over the country" in the local area, where toilets and other amenities remain closed.
"Roads towards the North Devon coast are now gridlocked," officers tweeted.
"We have vehicles from all over the country identified, please do not travel here.
"We will still be here when this is over so come back when it's safe to do so."
Some of the UK's beaches were a magnet for sunseekers - with Southend Beach in Essex particularly packed with visitors from as far away as Manchester and Leicestershire.
And the tourists - who have been blasted by local councillors as "foolish" and "irresponsible" - have left behind piles of rubbish, including Tesco bags, boxes of Corona beer, and plastic toys.
Southend councillors have said they now fear for the safety of visitors ahead of a potentially scorching Bank Holiday weekend this weekend.
Matt Dent, Labour councillor for Kursaal, blasted those travelling long distances to enjoy the seaside and warned of a potential second spike if the behaviour continues.
He said: "The more I see of this, the more I fear we're in for a second wave.
"It isn't Southend residents, it's people travelling from outside the borough - as far away as Manchester, from what I've heard - who seem to think lockdown is lifted, and Covid-19 is no longer a threat.
"It is a small minority who are acting in this foolish and irresponsible manner.
"But their behaviour impacts on all of us ultimately, if there is a resurgence in infections and we find ourselves facing a second, longer, far stricter lockdown through the summer and into the autumn."
Meanwhile, Labour council leader Ian Gilbert echoed his warnings, and added: "I do have concerns about the weekend. We want our open spaces to be safe and enjoyed.
"I am worried we could see an influx of visitors and we don't want to see social distancing break down. I think it's being managed as well as we can at the moment."
Their warnings come as the promenade between Chalkwell and Southend Pier has been temporarily widened to keep people socially distant while using the seafront.
The widened promenade has been made possible by a contraflow system installed by the council, allowing cars to travel in both directions, but with a reduced lane width.
All parking bays along the Western Esplanade are out of use, giving the public a great deal of extra space.
The seafront water fountains have also been turned off in a bid to dissuade visitors.
