First ‘Heat-Health’ alert of the summer

East Anglia, London and south east England have been put on Heat-Health alert as hot temperatures are forecast over the next couple of days.  Temperatures will peak across East Anglia and south east England during Friday and Saturday, where highs of 31°C are possible in some areas.  However the weather will be quite varied elsewhere with some parts of the UK having rather unsettled conditions and temperatures only reaching the low 20’s.

The 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. 

A Level 2 alert is triggered as soon as the risk is 60% or above for threshold temperatures being reached in one or more regions on at least two consecutive days and the intervening night. This is an important stage for social and healthcare services who will be working to ensure readiness and swift action to reduce harm from a potential heatwave.
