The Met Office has issued a rare amber warning for extreme heat, alerting that millions of people across the South of England, the Midlands, and parts of Wales will experience a hot spell next week. The warning, the most severe in four years, indicates that the general population may develop symptoms such as sunburn, heat exhaustion, and other heat-related illnesses.
Timing and Temperatures
The amber warning is in effect from 1am on Monday, June 22, until 23:59pm on Tuesday, June 23. Temperatures are expected to climb to around 30°C over the weekend, peaking at approximately 34°C on Monday and Tuesday. Some areas may see even higher temperatures.
Three Key Symptoms
The Met Office highlighted three primary signs of heat exhaustion: dehydration, nausea, and fatigue. According to the NHS, dehydration can be treated with fluids and oral rehydration solutions, but if left untreated, it can lead to serious health issues such as a critical drop in blood pressure affecting the kidneys, brain, and heart.

Advice for Staying Cool
To cope with the heat, the Met Office recommends:
- Keep out of the sun and avoid exercise between 11am and 3pm
