Extreme Weather Warning


For the first time temperatures of 40°C have been forecast in the UK and the Met Office has issued the first ever Red warning for exceptional heat.

Exceptional heat is expected to affect a large part of England early next week, with temperatures likely in the high 30s in some places and perhaps even reaching 40°C.  

To keep yourself and other safe please be aware of the following advice 

  • Look out for those who may struggle to keep themselves cool and hydrated. Older people, those with underlying conditions and those who live alone are particularly at risk.
  • If you live alone, ask a relative or friend to phone to check that you are not having difficulties during periods of extreme heat.
  • Stay cool indoors: Close curtains on rooms that face the sun to keep indoor spaces cooler and remember it may be cooler outdoors than indoors.
  • If going outdoors, use cool spaces considerately.
  • Drink plenty of fluids and avoid excess alcohol.
  • Never leave anyone in a closed, parked vehicle, especially infants, young children or animals.
  • Try to keep out of the sun between 11am to 3pm, when the UV rays are strongest.
  • Walk in the shade, apply sunscreen and wear a wide-brimmed hat, if you have to go out in the heat.
  • Avoid physical exertion in the hottest parts of the day.
  • Make sure you take water with you, if you are travelling.
  • Check the latest weather forecast and temperature warnings – you can find these on TV, radio, mobile app or website.
  • During warm weather going for a swim can provide much welcomed relief. If you are going into open water to cool down, take care and follow local safety advice.

Heatwaves and health 

Heat can affect your health more than you might think.

While everybody is at risk of dehydration, heat exhaustion and heat stroke, certain people are deemed to be more at risk.

These groups include:

  • elderly
  • infants and young children
  • people with chronic medical conditions, for example heart problems and respiratory difficulties
  • people with mobility problems.

Cool Spaces 

The Mayor's Office has produced a map of cool and shaded places of refuge for Londoners when temperatures are high. Have a look for your local, indoor and outdoor cool spaces, areas of tree cover and shade and water refill points.

The Met Office

The Met Office has comprehensive information on the possible effects of severe weather, and guidance on what can be done in preparation for, during and after severe weather events.

Individuals and businesses can register to be sent severe weather warnings by email from the Met Office.

Severe weather can manifest itself in many forms, for example:

  • severe gales and storms (including thunderstorms and tornadoes)
  • heavy snow and/or blizzards
  • extreme rainfall
  • dense fog
  • widespread icy roads and/or freezing rain
  • heatwaves.

Many of these can bring disruption to normal life, affecting transport, utility supply or causing damage to property and trees.
