A heatwave is set to hit London next week, with scorching temperatures forecast to leave the capital sizzling. Amber heat health alerts are in place from 12pm on Thursday until 8pm on Tuesday, as the mercury looks set to reach 34C or more.
Heatwave Threshold Expected
The Met Office has said that parts of the south and south east are likely to meet the heatwave threshold during the weekend. In London, this would mean three consecutive days with temperatures at 28C or above. The national weather service also gives a 40% chance of exceeding the highest ever temperature for June, which is 35.6C set in 1957 and 1976.
Daily Forecast
Greater London could be as hot as 32C on Friday afternoon. While Saturday might be cooler, temperatures are expected to rise again on Sunday and Monday. Each day between Sunday and Thursday is currently forecast to be at least 30C, with Tuesday being particularly warm and potentially reaching over 34C. The heat may also trigger thunderstorms in the South East and East Anglia early next week.
Expert Comments
Met Office meteorologist Alex Deakin said that such high temperatures are "pretty unusual even for the middle part of June." However, deputy chief forecaster Gregory Wolverson noted that we may not experience the "wall-to-wall sunshine and blue skies" of the May heatwave, with cloud and high humidity making it "rather oppressive" at times.
Health Alerts and Risks
The UK Health Security Agency (UKHSA)'s amber health alerts mean that the high temperatures are likely to significantly impact health and social care services. This could also result in a rise in deaths, especially among those aged over 65 or with long-term health conditions.
Water Safety Warning
There were 15 deaths in open water across the UK during May's hot weather, and the RNLI has issued a warning to those who may want to enter the water during the upcoming heatwave. Samantha Hughes, the national water safety partner at the RNLI, said: "With warmer weather approaching, it's important to remember that the water is still cold. Entering it unexpectedly can lead to cold water shock, causing a sudden increase in breathing and heart rate, which may trigger panic." She advised: "If you find yourself struggling in the water, remember to Float to Live: tilt your head back so your ears are submerged, relax and control your breathing. You may need to gently use your hands to help you stay afloat, and it's ok if your legs sink – everyone floats differently."
Continental Heatwave
Temperatures on the continent also look set to soar. It could exceed 40C in parts of France, including Paris, which would shatter the June record of 37.6C set in 1947.
