Britain is ready to bask in 32C heat on Sunday as the bank holiday weekend sunshine is set to continue.
The Met Office said temperatures could reach 32C today in the south-east of England, as thousands of people flock to seaside resorts and Notting Hill Carnival.
And things could get even hotter on Bank Holiday Monday, with forecasters predicting a high of 33C in the same region.
That would be a UK record for the August bank holiday.
In Scotland, where Monday is not a bank holiday, temperatures are expected to it 29C on Sunday.
The hot weather, brought in by warm air from France, is in stark contrast to the heavy rain that fell throughout much of August.
On Saturday, the mercury rose to 30.7C at Heathrow, west London, just shy of the record of 31.5C set in the same location in 2001.
In Gogerddan, near Aberystwyth, it was 27.4C - a new record for the highest late August holiday weekend temperature in Wales.
Aberdeenshire in Scotland could see 29C on Sunday, while Northern Ireland is likely to enjoy 24C.
Meanwhile, thousands of police officers will be on the streets of west London on Sunday as Notting Hill Carnival gets under way.
About one million people are expected to attend over the course of Sunday and Monday, with temperatures expected to reach at least 30C on both days.
Good morning. Dry and sunny for most, though cloudier at times in the far west and north, along with some high cloud across parts of England and Wales. A warm day for many, but hot in central and eastern areas. Latest: https://t.co/cQSfu1VDbo ^Sophie pic.twitter.com/wvU7pxzO44

The number of police officers at this year's carnival - 12,427, reflecting the number of shifts worked over the course of the weekend - is slightly down on last year.
Officers will be supported by about 900 event stewards on Sunday and approximately 1,100 on the typically busier Monday.
Ahead of the annual celebration, the Met's Superintendent Elisabeth Chapple advised carnival-goers to be prepared for very hot weather by taking water or refillable bottles and downloading the official carnival app.
She said: "You can find medical points, food stops and receive live updates on transport network delays."
Met Office forecaster Craig Snell said: "People certainly need to bring plenty of water with them and slap on the suncream."
