The United Kingdom has just experienced its warmest May day on record, with temperatures soaring to 28.5C in Wisley, Surrey. This figure officially surpassed the previous May high of 28.3C, which was recorded in both 2012 and 1999. The exceptional heat was felt across large parts of England and Wales, prompting many to enjoy the unseasonably warm conditions.
However, this spell of summer-like weather is set to be short-lived. The Met Office has indicated a significant shift in the weather pattern over the coming days. Following the peak of the heatwave, the country is expected to see a return to more typical spring conditions, characterised by cooler temperatures and an increase in unsettled weather.
Forecasters anticipate that the change will bring a risk of thunderstorms, particularly across southern and eastern areas, as the warm, humid air gives way to fresher conditions. These thundery downpours could be heavy in places, potentially leading to localised disruption. Temperatures are predicted to fall quite dramatically from their recent highs, moving closer to the seasonal average for late May.
The brief heatwave was largely attributed to a combination of high pressure systems drawing warm air from continental Europe across the UK. This atmospheric setup created stable conditions, allowing temperatures to climb steadily. While pleasant for many, the sudden rise in temperature also highlighted the variability of British weather.
Looking ahead, the outlook suggests a period of more changeable weather, with a mix of sunshine and showers. While the extreme heat has subsided, the transition phase could see some dramatic weather events before the pattern stabilises to more moderate spring conditions.
