Advice on keeping cool has been issued to the public in advance of the weekend heatwave.
The rise in temperature is expected in London and the South-east and has been given a Level 2 threshold by the Met Office, which requires a degree of alert and readiness due to an expected increase in humidity.
Temperatures in Maidenhead and the surrounding area are expected to reach 30°C tomorrow (Friday) and remain in the high 20s on Saturday and Sunday.
Buckinghamshire County Council has advised people to stay out of the heat, especially during the hottest part of the day and to stay hydrated.
It is also advised that people keep their homes cool by closing curtains and blinds and keeping bowls of cold water around the house.
The public has been asked to look out for others, in particular the isolated, elderly, ill or very young and to make sure they are able to keep cool.
The Met Office has warned that intense thunderstorms and flash flooding might follow the high temperatures so people should take extra care when travelling on the roads.
