The UK will sizzle more than popular holiday hotspots Greece, Spain, Turkey and Tenerife - as new weather maps for this week reveal Britain will hit our highest temperatures of 2025. The Met Office have revealed that the UK is set to see the mercury soar up to 29C (84.2F) as a mini-heatwave this week will see our hottest day for far this year.

Temperatures of 24C (75.2F) or 25C (77F) are forecast on Monday, rocketing each day until a peak on Wednesday or Thursday of 28C (82.4F), with a small chance of seeing 29C (84.2F). On Thursday swathes of the southeast will go above 27C, both Manchester and Cardiff will hit at least 24C - while Devizes in Wiltshire, Oxford, Gloucester and Worcester will all roast at 26C.

But across Greece and the Greek islands - popular holiday hotspots for British tourists - the temperature on Wednesday will peak at 21C (69.8F) and on Thursday just 23C (73.4F).

Meanwhile in the Canary Islands, Tenerife will reach 19C on Wednesday and 22C on Thursday - while on mainland Spain, Barcelona will reach only 20C on Wednesday and 22C on Thursday.

Across Europe other holiday destinations are even colder with Turkey set to chill at just 13C on Wednesday and 18C on Thursday.

During the night this week temperatures will drop down to at least low teens, so "we shouldn’t suffer too much with warm nights", Met Office meteorologist Craig Snell said.

He added: "We’re certainly on track to see the warmest spell of the year so far."

Each day this week is likely beat the hottest day of the year, which currently is April 24th when it hits 24C - with the peak set to be Thursday, Mr Snell said.

He added: "There will be plenty of sunshine around, the very north of Scotland at times will see some spells of rain, especially at the beginning of the week, but it’s going to be limited to the far north of Scotland.

"For a lot of the UK it’s going to be largely sunny."

Temperatures will be "markedly higher" than what they should be for this time of year, as at the end of April it is usually about 12C in the north and 16C in the south, so some areas could be more than 10C higher than the average.

Records for April and May are unlikely to be broken as the record for April stands at 29.4C, and May’s record is 32.8C.

But some local records at stations could be broken, the forecaster added.

It will be close to what the Met Office considers a heatwave in some areas but there is not likely to be a heatwave widely, Mr Snell said.

According to the Met Office, the definition of a heatwave is three consecutive days of temperatures exceeding the "heatwave threshold", which varies across the country.

The threshold is 25C for most of the UK, with slightly higher numbers for the South and East, and rising to 28C in London.

On Friday, temperatures will start to drop towards the average for the time of year, with temperatures in the high teens in the South and mid-teens in the North, Mr Snell said.
