Overview of hot weather over the next 5 days

An exceptional spell of hot and humid weather is now expected for much of England until Friday. Hot in the south again Monday, with isolated showers or thunderstorms in northern parts, and later moving east across southern and central parts. More widely dry and sunny through Tuesday, Wednesday and probably Thursday, becoming very hot, most likely the peak of the event. Confidence lowers from Thursday, still likely hot for many, but risk increasing of thundery showers spreading in from west later and clearing east during Friday. Very warm, even tropical nights, and uncomfortable nights for many throughout the whole week, especially in larger cities and especially in the south, with high humidity. Temperatures still potentially high up to the weekend, with the highest probabilities of this in the south and southeast, although the current signal is for less hot, more showery conditions to gradually spread from the west around this time. Regarding exacerbating factors, winds will be mostly light, offering little relief. Pollen levels will be widely high or very high. Air pollution levels will deterioriate, with widespread Moderate levels spreading to affect much of southern and central Britain from Monday, likely lasting through midweek.

Overview of hot weather over the next 6 to 15 days

Saturday, more unsettled and cloudier conditions probable in the north and west with temperatures near normal or warm. In the southeast, sunny spells with very warm and locally hot temperatures. Sunday, a band of rain moves east across the UK. This likely heralds a change to temperatures closer to normal though still warm in the southeast. For the rest of this period, confidence is low with temperatures likely above average with the chance of hot spells.

Overview of hot weather over the next 16 to 30 days

Low confidence in any detail, however, probabilities of warmer than average conditions and likelihood of hot spells appears to be greater relative to climatology for the end of June and into early July. Toward mid-July, weather possibly turning more unsettled with some moderation of temperatures likely.
