Tom Tobler, a forecaster with MeteoGroup, the weather division of the Press Association, said Saturday's weather is very likely to beat the current record of 29.7C reached in Bournemouth on Sunday.
"It's certainly going to be a very hot weekend with lots of sunshine.
"Temperatures are predicted to reach at least 31C on Saturday, which will make it the hottest day of the year so far.
"Temperatures will drop a few degrees on Sunday into next week but we can't see any sign of the hot weather changing over the next week.
"It's been a very hot start to July, and it's likely to last a while longer, for the next one or two weeks."
The north of the UK has seen the best temperatures over the last few days, with the highest recording of 28.8C in Castlederg, Northern Ireland on Thursday.

Yorkshire is likely to be the hottest area on Friday before the south welcomes the top highs.
The heat could lead to a few local thunder storms in the east of the country.
