Harry Styles shows off his rippling abs as he goes for a dip during the heatwave

POP heart-throb Harry Styles shows off his rippling abs by cooling off in the heatwave.

Yesterday, sun-lovers sizzled in 32.7C (90.8F) on the hottest day of the year — the sixth day in a row above 30C (86F).

Ex-1D star Harry dived into a bathing pond in North London.

An onlooker said: “He kept a low profile and went mostly unrecognised. He was swimming laps and practising his diving.”

Harry, 29, is on a break in the capital after wrapping up his global Love On Tour shows.

Harry, now dating Canadian actress Taylor Russell, 29, has said: “I feel like people who’ve discovered cold-water swimming are just so happy for you that you’ve also found it.”

The UK was hotter than Ibiza yesterday.

Friends frolicked in the sea at Brighton and Bournemouth, while racegoers dressed to the nines at Ascot, Berks.

Manchester, the Midlands and Wales were given a yellow warning for thunderstorms, ending at 9pm yesterday.

The temperature will hit 32C (89.6F) once more in the South East today before the longest September heatwave on record ends.

Temperatures will return to the monthly average of 17C (62.6F) by midweek.

Forecaster Stephen Dixon said: “There’s a chance above-average temperatures return by late September. It’s certainly looking likely.”
