An amber heat health alert has been issued across England, as temperatures are expected to reach above 30C today.
According to the Met Office's latest forecasts, much of the south of England will see temperatures between 31C (87.8F) and 32C by Thursday afternoon, with temperatures above 20C across almost all of the UK.
It would make for the hottest day of the year so far, beating the 29.4C (85F) recorded last Friday in Suffolk and coming after record-breaking spring heat.
By this weekend, temperatures are forecast to hit highs of 33C (91F).
