The UK is enjoying its warmest day of the year so far, with temperatures soaring into the low to mid-20s Celsius, particularly in South-East England. Forecasters predict highs of 26°C on Wednesday, surpassing the previous record of 20.9°C set on March 31 in Pershore, Worcestershire. This brief warm spell is attributed to high pressure building after Storm Dave, which recently caused significant disruption across the country with winds reaching 70mph. Met Office Chief Forecaster Paul Gundersen noted that while this warmth is unusual for early April, it is expected to be short-lived, with temperatures dropping by 10°C later in the week. The Midlands and East Anglia are expected to see the highest temperatures, while coastal areas may remain cooler and windier. Additionally, pollen levels are set to be very high, affecting many residents. Despite the warm weather, the Met Office clarifies that this does not constitute an official heatwave, which requires sustained high temperatures over several days. As the week progresses, a shift in weather patterns will bring a return to cooler, unsettled conditions.
