Britain is set for one of its warmest late-August bank holiday Mondays on record, with the Met Office predicting temperatures could reach 30 °C in parts of the West Midlands and north-west England. Highs of 27 °C are forecast for eastern Wales—threatening the nation’s 1991 record of 26.5 °C—while Northern Ireland could surpass its 1983 benchmark of 23.8 °C. Around 28 °C is expected for London’s Notting Hill Carnival, and most of England and Wales will remain sunny and dry through the day. The heat will be short-lived. Forecasters say the remnants of Hurricane Erin will reach Northern Ireland and Scotland’s Western Isles late Monday, spreading rain and gusts of up to 40 mph across much of the UK by mid-week. Daytime temperatures are projected to fall to the mid-teens by Friday as unsettled, wetter weather replaces the warm spell.
