Temperatures could hit 30C at the earliest point in the year on record in the UK on Thursday, the Met Office said.
Parts of southern and central England are expected to see temperatures reach 26C on Tuesday.
The warm weather will continue on Wednesday, with highs of 27C in London forecast.
Temperatures could rise to 30C in some places on Thursday, the forecaster said.
Met Office chief meteorologist Paul Gundersen said: “It is not particularly unusual to see warm and sunny periods in April where temperatures reach the mid-20s.
“This has occurred as recently as 2018 and 2019, for example.
“However, it is more unusual to see temperatures reach the high-20s, and if we see 30C this week, it will be the earliest point in the year in which we have achieved that threshold.”
Where is the heat coming from this week? ️

A broad area of high pressure is currently positioned over the UK, leading to sinking air that warms as it descends. Combined with prolonged sunshine, this is expected to push temperatures up to 29°C in southern areas by Thursday ☀️ pic.twitter.com/41ceewIrA1
Nicola Maxey, press officer at the Met Office, said: “As high pressure continues to dominate the UK weather we will see the temperatures building day on day through the week with Thursday seeing the peak of the heat with 29C or even a chance we could see 30C.
“Friday temperatures will start to dip across much of the UK as the high pressure starts to pull away.”
The highest recorded April temperature was in 1949, when Camden Square, London, recorded 29.4C.
For May, the highest temperature recorded was 32.8°C on May 22 1922, in Camden Square.
