Brits packed out bars, pubs, parks and beaches to enjoy a refreshing drink last night in a bid to cool off after another day of glorious weather.
But social distancing measures and face masks were the furthest things on everyone's minds after a day spent in the sunshine.
The mercury topped temperatures of 95F (35C) and in what has been the hottest weekend this year so far, experts are warning crowded bars are more dangerous than planes.
Preston in Lancashire is the latest city to be locked down and it's been revealed that half of all new coronavirus cases are under the age of 30.
As young revellers queued to get into a bar none were spotted wearing face masks and there were no obvious signs of social distancing.
To try and reach younger people Preston Council has launched a powerful "don't kill granny" message to encourage the youngsters to follow the rules.
Dr Julian W Tang, honorary associate professor of respiratory sciences at the University of Leicester, has said he would "rather fly on a plane than go to a pub".
He said being in a busy pub is worse than being on an aeroplane because planes have better ventilation.
Dr Tang said: "If the air space is poorly ventilated, that air that's full of the virus is not going to go anywhere.
"It's going to linger there until the virus dries up and dies over time," he said.
He went on to say the most common method of transmission in the UK is probably "conversational exposure".
Dr Tang added that when people laugh they produce a lot of air, so if someone in a group in the pub makes a joke then they are massively exposed to exhaled air from the laughter around them.
He said: "To be honest, on a plane, the danger is from your nearest neighbours because that air is not filtered away quickly enough before you inhale it. That's the main risk on a plane.
"I don't see planes as a major risk. If you ask me would I rather fly on a plane or go to a pub, I'd rather fly on a plane."
