History

Historical Context

The 1976 UK heatwave, driven by a high-pressure system from late May to 27 August, produced a 16-week drought, daily temperatures above 32 °C and a record 35.9 °C in Cheltenham, causing about 15,000 excess deaths. That summer remains the benchmark for British heat, informing today’s policy debate involving the Met Office, the TUC and climate-risk analysts.
