The hot weather which the UK has been enjoying is expected to last into the weekend.
Temperatures will temporarily dip mid-week to the low 20s before soaring again on Friday, possibly lasting through until Sunday.
London is expected to see the best of the sweltering temperatures on Tuesday, while the north of England will also climb to around 28C - finally enjoying the same highs as the south after averaging around 24C over the last few days.
The weekend of glorious weather continued as people returned to work on Monday, with a high of 29.6C recorded in Lee-On-Solent in Hampshire, just shy of the 29.7C reached in Bournemouth on Sunday which marked the hottest day of the year so far.
However, it was markedly cooler across the North Sea coast of Scotland and England, where Donna Nook in Lincolnshire peaked at only 16C.
While the sunshine is not unusual for July it is above average, said Andy Ratcliffe, meteorologist for MeteoGroup, the weather division of the Press Association.
"In the middle part of the week the weather will get cooler but still warm, to around the low 20s," he added. "But it will pick up again in time for the weekend and should last through to Sunday.
"Past that it is hard to be certain, but we don't have much rain at all forecast for the next seven-to-10 days."
But police have warned of the dangers of cooling off in open water after a 17-year-old boy died while swimming in a lake at an old quarry.
Russell O'Neill, from Worcester, had been swimming at Gullet Quarry near Malvern in Worcestershire when he failed to resurface on Saturday afternoon. The teenager's body was recovered by a dive team from South Wales Police at around 4.50pm.
