UK Parts of southern England have recorded the hottest day ever after temperatures exceeded 31 degrees Celsius.
Temperatures reached 31.6C in Heathrow and 30.2C in Cardiff.
The hot weather is predicted to continue tonight and into tomorrow, the day the last day of Covid-19 restrictions in England are to be lifted.
As the week progresses, the maximum temperature is likely to remain in the west.
The high temperatures mark the start of an official heatwave across the UK, as in London and the South East, temperatures must exceed 28C for at least three days to record a heatwave, and Sunday is the third day.
To escape the heat, thousands headed to the coast along beaches such as Brighton, Bournemouth and Weston-super-Mare, which were packed with visitors.
In Dorset, the seafront car parks reached capacity, the Durdley Door Road access was closed as the car park was full, and the Pier Approach flyover at Bournemouth was also closed due to traffic volume.
