Heatwave Forecast for the Bank Holiday
The Met Office predicts a warm spell over the bank-holiday weekend. High pressure will bring fine weather, though north-west Scotland will stay cooler. Forecasts show a peak of 30 °C in London, 27 °C in Exeter and Nottingham, and high-20s elsewhere.
Recent Climate Background
The heatwave follows the UK’s hottest summer in 2025, which brought drought, delayed reservoirs and 40 % loss in tree-planting projects. Scientists warn a “super El Niño” could emerge by June, intensifying weather.
Temperature Outlook
Temperatures will range from 30 °C in London to 27 °C in Exeter and Nottingham. Met Office defines a heatwave as three consecutive days at or above a set temperature and expects it from Sunday in south-east England, spreading across England. A 40 % chance of 33 °C in southern England on Sunday would beat the May record of 32.8 °C set in 1922.
Health Alerts and Public Risks
UKHSA issued yellow alerts for East Midlands, West Midlands, East of England, London and South East, warning risk to vulnerable people. Heat raises concerns about heat-related illness among elderly and those with conditions, while sunshine will draw crowds to beaches and beer gardens, raising exposure.
Official Statements & Responses
The Met Office says pressure will bring weather, though north-west Scotland will stay cooler. It warns heatwave thresholds are likely to be met in south-east England from Sunday. UKHSA advises staying hydrated, avoiding exposure and monitoring vulnerable groups.
Criticism & Opposition
Health officials warn hot days could strain services, while critics say public underestimates heat.
Conflicting Forecasts & Gaps
Met Office forecasts a 30 °C peak for Monday; Tom Morgan cites a 40 % chance of 33 °C on Sunday, leaving the record outcome uncertain.
