above the threshold for a heatwave, which is 28°C in London and lower elsewhere. Several station records in Scotland and Northern Ireland were broken, with some dating back more than 50 years. The highest temperature recorded during the heatwave was 35.8°C in Faversham on 1 July. Interestingly

in the 1961-1990 averaging period only London and Hampshire recorded six or more days over 28°C, by the latest decade (2014-2023) this has spread across much of England and Wales, with frequencies in the south east increasing to over 12 days each year in many counties. The expansion of the area
