The Met office has issued a level three heatwave alert for the eastern part of England where temperatures are expected to exceed 30C. London and south-east England are on a level two alert, meaning heatwave conditions are also likely this week.
Public Health England (PHE) urged people to stay safe and advised them to drink plenty of water, wear loose-fitting cotton clothing, and to stay out of the sun between 11:00 and 15:00 BST. Temperatures of 30C have already been recorded in Cambridge, Writtle in Essex and Heathrow on Tuesday.
PHE also urged people to look out for the elderly and those with underlying health conditions who may be particularly vulnerable as temperature rises.
Dr Thom Waite, a consultant in public health medicine at PHE, said: "Each year we hear stories of people who have fallen seriously ill because, even though it's hotter, they may wear clothes which are too warm for hot weather, they may not drink enough or try to do too much."
He added that people should "stay hydrated, look out for others and keep an eye on forecasts".
