View current Weather-Health Alerting situation

Overview of hot weather over the next 5 days

Remaining unsettled over the weekend, with spells of rain or showers at times. Warm or very warm in the southeastern half of England on Saturday, Sunday and Monday, with 25-26C possible in some spots. Likely cooler by Tuesday, although confidence is lowering in exact temperatures during this period.

Overview of hot weather over the next 6 to 15 days

Likely remaining unsettled at first, at least in the north, but probably tending to become drier and more settled, especially in the south. This may bring some warmer air from the near continent, potentially allowing temperatures to rise from mid-September. Confidence in temperatures meeting thresholds is low at this stage, however.

Overview of hot weather over the next 16 to 30 days

Potentially settled at first, with a risk of temperatures being above average, however confidence is very low. Heat-health alert thresholds also become increasingly difficult to reach by the end of the period as we move into early October.
