Certain regions of the United Kingdom are nearing a two-week stretch of extreme heat. Southern England has endured 13 consecutive days meeting heatwave thresholds. With Merryfield, Somerset, hitting 30.6C on Thursday, the nation has experienced 12 straight days at or above 30C, a duration unmatched since 2006. While northern air currents may provide minor relief this weekend, some areas will likely remain in heatwave conditions.
This prolonged event is fueled by rapid climate shifts, with average UK temperatures rising 1.33C since the late 20th century, and hottest-day peaks warming even faster. Meteorological factors, specifically a stationary high-pressure system creating a heat dome, have trapped warm air over Western Europe. This process prevents cloud cover and intensifies surface heating.
The year 2026 has already broken monthly temperature records in May and June. While this event is significant, it remains below the 16-day record set in 1976. Nevertheless, the intensity is notable; the country has logged six days exceeding 35C this year. The Met Office indicates that such occurrences are becoming more frequent and severe, with the number of days over 30C quadrupling in Greater London. Although the upcoming weekend may bring slightly lower temperatures, forecasts suggest warm, dry weather will persist through the month.
