The Met Office has confirmed that the UK will experience its third heatwave of the year over the coming days, with temperatures potentially climbing to 35°C in some areas. This follows previous heatwaves in May and June.
Less Humid Conditions Expected
Unlike the earlier heatwaves, forecasters predict conditions will be less humid this time, featuring "lower peak temperatures and fewer exceptionally warm nights". The Met Office explained that high pressure will "bring extensive sunshine and light winds to many southern areas, allowing temperatures to build steadily through the week".
Regional Temperature Forecasts
Certain southern English regions could see highs approaching 35°C, while "much of England and Wales will be hot, and the heat will extend to parts of Scotland and Northern Ireland too". Southeast England is expected to meet official heatwave criteria by Monday's end, with more regions likely to follow as temperatures rise.
Projected temperatures for southern UK include peaks of around 32°C on Monday and Tuesday, 33°C on Wednesday, 34°C on Thursday, and up to 35°C on Friday and Saturday in select locations.
Heatwave Definition
A UK heatwave threshold is met when an area records at least three consecutive days with daily maximum temperatures at or above the heatwave temperature threshold. This threshold varies by county, but for most of the UK it is 25°C. In some central and southern areas, the threshold may be 26°C, 27°C, or 28°C.
Water Safety Warning
Before the warm weather, the Met Office warns those planning to "enjoy the water". People are advised to check water temperatures, as "our seas and river temperatures are low enough to cause cold water shock when 15°C or lower". Additionally, wearing a wetsuit is recommended for extended time in the water. The Met Office also notes that wearing a life jacket or swimming buoy can increase survival chances if cold water shock occurs.
