The United Kingdom recorded its hottest May day on record on Monday, May 6, 2024, with temperatures peaking in west London [1, 2, 3].
This extreme heat represents a significant departure from seasonal norms, signaling a volatile shift in spring weather patterns across the British Isles. The event coincided with the early-May bank-holiday weekend, bringing unprecedented heat to millions of residents.
Reports on the exact peak temperature varied slightly across agencies. The BBC reported a maximum of 35.1 °C [2], while Sky News recorded 35 °C [1]. The Evening Standard reported the figure as 34.8 °C [3]. This surge was driven by a strong high-pressure system and a heatwave affecting the region [1, 2].
Sky News reporter Steff Gaulter said, "We may even see 36 °C later today somewhere in the South East" [1].
The heat extended into the night, creating conditions known as a "tropical night." At Kenley Airfield in London, the overnight minimum temperature did not fall below 21.3 °C [2]. A BBC Weather Correspondent said that a minimum temperature above 20 °C is the threshold for such a classification [2].
Weather monitoring centered on west London and the South-East of England, where the high-pressure system remained most concentrated [1, 2]. The Met Office monitored the surge as temperatures climbed to levels typically reserved for mid-summer months [1, 2].

The occurrence of a 'tropical night' and record-breaking daytime highs in May suggests an intensifying trend of early-season heatwaves in Northern Europe. Such anomalies can strain infrastructure not designed for extreme heat and may indicate a shift in the timing of seasonal temperature peaks.
