Parts of England have been put on Heat-Health alert as the hot temperatures continue into the weekend.

Temperatures are expected to climb close to heatwave thresholds across the East Midlands and Yorkshire and the Humber regions during Friday and Saturday, with highs of 29°C expected. The highest temperatures transfer southwards to affect East of England, Southeast England, London and parts of Southwest England during Saturday and Sunday. Saturday will see the hottest day of the year with temperatures reaching the low 30s in the south east.

The Heat-Health Watch system operates in England from 1 June to 15 September each year in association with the Department of Health.

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.

Local authorities, professionals and community groups can prepare for hot weather by reviewing the Heatwave Plan on the PHE website.

Dr Angie Bone, Heatwave Plan lead for PHE, said: “While many people enjoy hot weather, high temperatures can be dangerous, especially for people who may be particularly vulnerable such as older people, young children and those with serious illnesses.

“The Heatwave Plan is an important component of overall emergency planning and sets out a series of clear actions that can be taken by healthcare organisations, local authorities, professionals working with vulnerable people, and individuals to help keep people safe during extreme heat.
“Everyone can enjoy the sun safely by keeping out of the heat at the hottest time of the day, avoiding sunburn and staying hydrated with plenty of cool drinks. The elderly and those with long-term illnesses are particularly vulnerable to the effects of very hot weather, so it’s important to look out for them and keep indoor areas as cool as possible.”
