The UK experienced its hottest day in two years on Monday, with temperatures reaching 34.8°C in Cambridge, as sunseekers flocked to parks and beaches. This heatwave, influenced by warm air from Europe, prompted a surge in coastal tourism, particularly in places like Southend, where temperatures hit 33°C. However, the warm weather was accompanied by a yellow weather warning for thunderstorms in northern regions, with over 15,000 lightning strikes recorded. Despite the heat, conditions were more humid and uncomfortable in central eastern England, while areas like Manchester and Edinburgh remained cooler. Forecasters predict a return to more typical temperatures in the coming days, with scattered showers expected. The warm sea temperatures have also made swimming appealing at various beaches, particularly in the south and parts of Wales.
