Summary

The Met Office predicts a potential sixth heatwave for Britain next week, with temperatures reaching up to 29°C in southern England. The forecast indicates warm weather building from late September 17th, driven by high pressure and warmer air from the Atlantic and continent. While this final heatwave is not guaranteed, it follows an exceptionally hot summer that saw numerous days over 30°C and led to water supply strains across much of the country.

Story summary

The Met Office predicts that parts of Britain could experience a sixth heatwave in late September, with temperatures reaching up to 29°C in southern England. This period of warm weather would be notably unusual for the season, offering one last taste of summer before autumn sets in firmly. Southern England is expected to see temperatures climb into the mid- to high-20s by the middle of next week and into the upper-20s by the end, following a series of heatwaves during late spring and summer. The unusual weather patterns stem from a deep low-pressure system forming west of the UK, dragging warmer air up from continental Europe and the sub-tropical Atlantic Ocean. High pressure is then expected to build across Britain over the weekend, bringing settled conditions with temperatures gradually increasing each day.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
