Met Office verdict on when new heatwave will end as Brits face 35C scorcher A new Met Office forecast predicts temperatures could soar up to 35C in some parts of the UK this week as more sweltering conditions arrive A third heatwave of the year in the UK will see scorching temperatures as high as 35C, the Met Office has said as it also gave its verdict on when the heat surge will end. The national weather agency says that parts of southeast England are forecast to experience official heatwave conditions by the end of today (Monday) with the mercury rising steadily higher through the week. Southern regions of the UK can expect highs of approximately 32C on Monday and Tuesday, climbing to 33C on Wednesday, 34C on Thursday, with some isolated spots possibly hitting 35C on Friday and Saturday. Conditions are anticipated to be less humid compared to June's heatwave, the Met Office noted. In a statement, the Met Office also revealed when it believed the third heatwave would end. The forecaster indicated that the "very warm conditions" will probably extend into the weekend, albeit with rising humidity and an increasing possibility of showers or isolated thunderstorms. It added: "Into early next week, temperatures are likely to trend down slightly, although many areas will stay dry, fine and still warm." Meanwhile, the UK Health Security Agency has issued a series of amber heat health alerts across England. The six affected areas are the East Midlands, West Midlands, East of England, London, South East and South West. The amber alert means "significant impacts are likely across health and social care services due to the high temperatures including a rise in deaths, particularly among those aged 65 and over or with health conditions. There may also be impacts on younger age groups". Met Office Deputy Chief Forecaster Steven Keates commented: "Parts of the UK are entering heatwave conditions - the third heatwave in the UK so far this year. However, unlike the May and June heatwaves, we are not expecting this heatwave to be record-breaking. "Temperatures this week are not expected to reach the highs we witnessed last month, though parts of southern England in particular are likely to see several days in the low 30s Celsius, and a few places could reach 34-35C later this week. "Night-time temperatures again will not be as high as what we experienced in June, though some larger urban areas are likely to remain in the high teens Celsius overnight, especially later in the week, and there is a chance that a tropical night (where temperatures do not fall below 20C) may be recorded in a few places. "Much of England and Wales will be hot, and the heat will extend to parts of Scotland and Northern Ireland too, though here peak temperatures are more likely to be in the upper 20s Celsius. "With high UV and high temperatures, people should take the usual precautions with the heat and the sun." Provisional Met Office figures reveal that June 2026 was England's warmest June on record for average mean temperature, while the UK and Wales registered their second warmest June in records stretching back to 1884. Minimum temperatures in June 2026 were more than 2C above average across the UK, with England recording overnight temperatures 2.6C above the norm. Northern Ireland experienced its second highest minimum temperature since 1884.
