Severe weather advice

A Heat-Health Watch system operates in England and Wales from 1 June to 15 September each year in association with the Department of Health and the Welsh Assembly.

The Heat-Health Watch system comprises four levels of response based upon threshold maximum daytime and minimum night-time temperatures. These thresholds vary by region, but an average threshold temperature is 30 °C by day and 15 °C overnight.

Current watch level: Level 1 - Summer Preparedness

Issued at: Sunday 11 July 2010 at 08:00

Temperatures are not expected to reach heatwave threshold values until further notice. This message is reviewed daily and only updated if the alert status changes.
