London could be heading for another scorching heatwave – and this one may refuse to let up! Forecasters are predicting the capital could bake for as long as ten days, with temperatures climbing as high as 32C after an already record-breaking spell of extreme heat. According to BBC Weather, the hot weather is expected to begin this weekend, with temperatures forecast to reach 28C on Saturday. If the forecast holds, London could then remain under blazing conditions every day through to Monday, July 13. The forecast suggests daily highs of between 28C and 32C throughout the period. That would comfortably meet the criteria for an official London heatwave, which is declared when temperatures reach at least 28C on three consecutive days. There is still room for the forecast to change over the coming days. But the prospect of another early July heatwave is also being backed by the Met Office, adding weight to predictions that the capital could be facing another prolonged spell of sweltering weather. The warning comes just days after the UK smashed its provisional June temperature record. Fresh data confirmed the mercury reached an astonishing 37.7C at Lingwood in Norfolk on Friday, making it even hotter than first reported. That reading overtook the previously announced 37.3C recorded at Santon Downham in Suffolk on the same day. It also surpassed the long-standing UK June record of 35.6C, which had stood since 1976, by more than 2C. Such a leap is especially striking because UK temperature records have traditionally been broken by only tiny margins. Last week's heatwave repeatedly rewrote the record books as temperatures surged across the country. Scientists also issued a stark warning. They said the June 2026 heatwave would have been virtually impossible 50 years ago, with human-driven climate change driving more frequent and more intense extreme heat events. The extraordinary conditions prompted the Met Office to issue a rare red warning for extreme heat. It marked the first time the agency had kept such a warning in place for three consecutive days. The heatwave left disruption in its wake. Schools and nurseries closed, ambulance services experienced record demand, hospitals declared critical incidents, train services were cancelled, court hearings were delayed and Kent introduced a hosepipe ban as water demand soared. Deputy chief forecaster Tony Wisson said high pressure extending from the Azores is expected to strengthen across much of the UK toward the weekend. That should bring warm or very warm weather to many parts of England and Wales, although some rain could still affect the far north. He said temperatures may approach the high 20Cs across parts of England, with some areas of the South East potentially reaching 30C. Wales is also expected to see temperatures climbing into the mid to high 20Cs. Wisson said another period of heatwave conditions is becoming increasingly likely in some areas. However, he added that temperatures are not currently expected to reach the extreme highs or humidity experienced during last week's record-breaking spell.
