New analysis from the University of Reading has revealed that Reading experienced its hottest May day on record this spring, reaching 32.8°C on 25 May.
Researchers also recorded the largest temperature range ever observed in a single month in Reading, with temperatures rising from below freezing in mid-May to more than 32°C less than two weeks later.
Experts say the extreme heat was caused by a prolonged area of high pressure, known as a “heat dome”, combined with unusually dry ground conditions that intensified temperatures.
The findings highlight the growing impact of extreme weather on businesses, infrastructure and communities. Heatwaves can affect productivity, place pressure on transport and water networks, and create challenges for sectors such as agriculture and construction.
Researchers warn that climate change is increasing the likelihood of more frequent and intense heatwaves, underlining the importance of climate resilience for businesses and communities across the Thames Valley.
