The heat continues to build today By Brian Gaze [Published 08:00 23/06/2026] The heatwave affecting much of the UK continues today, with temperatures likely reach higher levels than yesterday. In the south 35°C is possible, and tomorrow is likely to be even hotter. However, the peak of the heat will probably occur on Thursday. 14 day weather forecast video Issued 16th June 2026 Very hot in southern and central areas Sunny periods develop widely today, but a few isolated thunderstorms are possible. In the north it becomes very warm, whilst southern and central areas will be very hot and humid. The existing June temperature record could be challenged. Widespread rain in the south overnight is likely to act as a cap on maximum temperatures today, as much of the sun's energy will be used to evaporate moisture rather than heat the ground, and cloud cover could bubble up at times. Therefore, the highest values being modelled, around 37°C to 38°C, now seem unlikely to be reached. The temperature range across the UK will probably be from 22°C in the far north west to 34°C or 35°C in the south. Check the weather radar for the most up to date view.
