Brief Return of Summer-Like Heat Across the UK
9/7/2026, 7:47:19 PM
Background & Context
The Met Office has confirmed that the United Kingdom has provisionally experienced its hottest summer since records began nearly 150 years ago. Five heatwaves between May and August pushed much of the country into drought, sparked wildfires and caused travel disruption. The seasonal mean temperature for June-July-August was 16.5 °C, surpassing the previous high of 16.1 °C set in the prior year. Although the all-time UK record of 40.3 °C was set in Lincolnshire in July 2022, the highest temperature of the current summer was recorded on 13 August at Kew Gardens, when the mercury reached 38.1 °C. Temperatures of 37 °C or higher were observed on three separate days, bringing the total number of UK occurrences above 37 °C to twelve since records began, three of which have occurred this year.
Forecast Details and Data
A southerly wind drawing hot, humid air from continental Europe is expected to raise temperatures above average on Sunday. Forecasts indicate:
- South-east England: peaks of 27–28 °C.
- Central-southern England and the Welsh Marches: mid-20s °C.
- South-west England and eastern Wales: highs around 25 °C.
- North of England: low 20s °C.
- Eastern parts of Northern Ireland and Scotland: afternoon highs of 21–22 °C.
The warmth is projected to fade by Monday, with cooler, changeable conditions returning early in the week. By Tuesday, highs are expected near 20 °C in London and the south, and around 16 °C in Manchester and the north of England.
Official Statements & Responses
BBC weather analysis adds that low-pressure systems will bring wet and windy conditions, especially to northern regions, after the Sunday heat spike. It also states that a return to heat-wave conditions is unlikely over the next ten days.
Impact and Outlook
The short-lived heat is expected to provide a brief respite from the drought-related stresses of earlier heatwaves, but the rapid return to cooler, unsettled weather will limit any lasting agricultural or health benefits. The forecasted rain and stronger winds later in the week may help alleviate lingering dry conditions, though the Met Office cautions that the overall summer remains unusually warm.
Timeline
