Britain has recorded its hottest day of the year so far, with temperatures predicted to soar as high as 35C (95F) in London and southern England.
Shortly before midday on Saturday the Met Office said a temperature of 30.8C had been recorded in Charlwood, Surrey, and that it could approach the all-time record for June of 35.6C, reached in Southampton in 1976.
Forecasters said the east Midlands and south-east England would experience the biggest jump in temperatures on Saturday, soaring into the mid 30s. The capital was expected to be hotter than Hawaii on Saturday afternoon, after temperatures exceeded 30C in Scotland and Wales on Friday. Pollen counts and UV levels were expected to be high or very high for most of the UK.
The Met Office meteorologist Alex Deakin said: “The vast majority of the UK will stay dry with sunny spells but the temperatures will be a talking point.”
At Glastonbury, where dozens of festivalgoers have been treated for heatstroke over the last two days, organisers have been handing out free sunscreen and advising people to drink sensibly. Temperatures were expected to climb to 29C in Somerset – where the festival is located – on Saturday.
Management at Lord’s cricket ground were also encouraging attendees to turn up with suncream, a hat and a water bottle for the Cricket World Cup matches.
Western and north-western parts of the UK were forecast to be cooler and cloudier than in recent days – with temperatures likely to be around 22C on average. Outbreaks of rain and thunderstorms could hit eastern Scotland and north-eastern England later on Saturday.
The Met Office issued a severe weather warning for lightning in Northern Ireland and south-west Scotland on Saturday.
Meakin said Saturday night further south would be warm, humid and “tricky for sleeping”, but by Sunday a cold front would push building heat in the UK away and most places would return to more average conditions for June, including temperatures around the high teens and early 20s.
The UK experienced its previous hottest day of the year on Friday – with the temperature reaching 30C at around 3.50pm at Achnagart in Scotland.
Temperatures in France on Friday climbed to 45.9C – nearly two degrees higher than its previous record – while Spain continued to battle wildfires as most of western Europe continued to swelter in an extreme heatwave.
The heat has been caused by hot air pushing up from northern Africa, with Germany, Poland and the Czech Republic all recording their highest ever June temperatures this week.
