Here’s the latest on UK May heatwave records.
- The UK saw the hottest May day on record in late May 2026, with London’s Kew Gardens reporting about 34.8°C on Monday and subsequent readings pushing beyond 35°C in some areas. This shattered the previous May-day high and triggered national coverage.[2][6]
- Wales also logged its warmest May day on record around the same period, with places like Hawarden Airport hitting the high 30s Celsius, contributing to a wider pattern of unprecedented May heat.[2]
- Meteorologists warned that the heat was driven by a strong high-pressure system bringing extreme warmth earlier than typical for the season, and they cautioned that climate change is making such events more frequent and intense.[5][2]
- In addition to daytime highs, nights were unusually warm for May in several locations, with reports of record or near-record May-night temperatures in parts of the country.[3]
- The Met Office and BBC coverage noted the potential for continued hot conditions into the latter part of the week, along with concerns about heat health impacts and the strain on water resources and infrastructure.[6][5][2]
