The United Kingdom is experiencing a summer with more days exceeding 30C than recorded in 1976, a year previously considered a benchmark for hot summers. Data from Reading University's Atmospheric Observatory indicates 15 days have hit these high temperatures this year, compared to 14 in 1976. Five of these days rank among the top 20 highest temperatures recorded at the university since 1908.
Experts suggest that this continuous extreme heat signifies a shifting climate, with such hot and dry summers becoming more frequent and posing significant dangers to public health. Estimates suggest that over 2,700 people may have died from heat-related causes in England and Wales during recent exceptionally hot weather in May and June.
Parts of south-east England have officially entered a heatwave, with temperatures expected to remain high throughout the week and potentially meet heatwave thresholds for up to 14 days in some regions. Amber heat health alerts are in effect for the Midlands and southern England, warning of significant impacts on health and social care services, including a rise in deaths, particularly among the elderly or those with pre-existing health conditions. Yellow alerts are in place for northern England. The UKHSA has also cautioned about a potential increase in water-related incidents.
In response to the extreme heat, some train services have been cancelled or are operating at reduced speeds to ensure railway safety, with passengers advised to travel only if essential and to check for timetable changes. No significant rainfall is forecast for the UK this week, prolonging the dry conditions.
