Summary
36.9°C in Suffolk set a new provisional UK June record on Friday, prompting pharmacists and the MHRA to warn that extreme heat can reduce the stability and effectiveness of common medicines.
25°C is the storage limit for many prescriptions, and officials urged patients to check labels and avoid leaving drugs in direct sunlight, hot cars or on windowsills during the heatwave.
3 hospitals have declared critical incidents, according to The Sun, with reports of failing MRI scanners, radiotherapy machines and cooling units, while appointments were canceled as the NHS struggled with the heat.
Red extreme-heat warnings remain in place across the East of England, London and the South East, with amber alerts covering much of the rest of the country as a wider European heat dome drives the surge.

UK Heatwave 2026: Record Temperatures, Medicine Risks, and Urgent Healthcare Adaptation
Overview
In June 2026, the UK experienced an unprecedented and record-breaking heatwave, driven by a widespread heat dome effect across Europe. This event began when air sank through the atmosphere, compressed and heated up as it reached the ground, and dried out, which prevented cloud formation. As a result, strong sunshine further intensified ground temperatures, leading to a persistent spell of hot and humid weather. These severe conditions triggered rare red extreme heat warnings for central and western England and Wales, placing immediate strain on public services and highlighting the urgent need for better heat adaptation.
