Temperatures are set to reach around 22C across most of Scotland, while parts of England may see temperatures as high as 28C - higher than usual for the time of year - making it as hot as Barcelona and parts of the Canary Islands.
The improved weather will be good news for the organisers of the Edinburgh Festival Fringe, with a largely dry day on Saturday and just the odd chance of a shower in the evening and on Sunday. Football fans will also enjoy the sunshine as they flock to grounds around the country for the opening weekend of the season in the lower leagues and the second round of top flight fixtures.
After a strong start to July, in which parts of England saw record breaking temperatures, much of the rest of the month was a damp squib.
The improved weather this weekend will be a welcome boost for those holidaying at home and parents desperate to get children outdoors during the school holidays.
Gareth Harvey, a forecaster with weather organisation MeteoGroup, said dry and sunny weather is likely across much of the country throughout the weekend, He said: “Saturday is probably going be the better of the two days in general across the UK.
“Temperatures are looking at getting up to 25C or maybe 26C in the South East, with the London area seeing the highest temperatures.
“On Sunday it will reach up to 27C or 28C, again in London, but with around 26C quite widely across England, especially in central and south-eastern parts of the country.”
