A warm spell is expected in the UK on Sunday, with temperatures potentially reaching 28C (82F) in parts of south-east England. The warmth is being driven by a southerly wind bringing hot and humid air from continental Europe, where temperatures have been above 40C in some areas. High pressure has built up over southern Europe, contributing to the extreme heat in countries such as Spain and France. Temperatures are expected to be significantly higher than average for early September, but the warmth will be short-lived, with rain and cooler weather returning by Monday.

Story summary
Temperatures in the UK are expected to rise significantly on Sunday, with some areas potentially reaching 28C (82F). A southerly wind will bring hot and humid air from continental Europe, pushing UK temperatures above average. This warmth is due to high pressure building in from the south, where parts of central and southern Europe have been experiencing a spell of intense heat, with some locations exceeding 45C. In particular, Spain has seen its hottest day of 2026 so far on Thursday, with temperatures reaching 45.7C in Huelva. The warm air will bring unseasonable warmth to the UK, with areas in south-east England potentially reaching highs of 27 or 28C, while other parts of England and Wales will see temperatures in the mid-20s Celsius.

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.
