Heatwave Advice


Heatwave Advice

London will be faced with scorching hot days and equally muggy nights as a hot weather system moves in from the south.  

The Met reports there is a 90% probability the next few days could be classified as a heatwave in London as temperatures climb reaching highs of 33C on Tuesday, 34C on Wednesday and 35C on Thursday.

The temperatures will remain high overnight into Wednesday, making it uncomfortable to sleep with overnight temperatures of 24C.

It comes as medical experts warned that the searing temperatures could turn fatal for millions of vulnerable Brits.

Health chiefs say that a toxic cocktail of hot weather and high pollen could be “extremely” hazardous for around five million people who suffer from asthma or have difficulty breathing who are urged to keep up their medication..

Follow these essential tips to keep cool and safe:

PHE Beat The Heat

  • Stay tuned to the weather forecast on the TV or radio, and look at the Met Office London Weather Forecast
  • Drink lots of cool drinks
  • Stay in the shade whenever possible, and try to keep out of the sun between 11am and 3pm
  • Apply sunscreen of at least SPF15 with UVA protection
  • Wear UV sunglasses
  • Wear light, loose-fitting cotton clothes, a hat and light scarf
  • Carry water with you if travelling on public transport (it is best to drink 15 minutes before travelling)
  • Look out for others, especially vulnerable groups such as older people, young children or animals
  • Never leave anyone in a closed, parked vehicle, especially infants, young children or animals

Check on vulnerable family members or neighbours

People who are elderly or who have serious medical conditions, particularly heart or breathing conditions, are more vulnerable to serious ill effects in a heatwave.

You can help by visiting, perhaps more frequently, and encouraging them to:

  • Drink water or fruit juice regularly
  • Wear loose cotton clothing
  • Identify the coolest room in the house, so they can go there to keep cool
  • Keep rooms cool by closing curtains
  • Close windows and curtains while the room is cooler than outside and, if it is safe, open windows at night when the air outside is cooler
  • Avoid going outside in the hottest part of the day (11am to 3pm)
  • If they do need to travel, to carry water with them. It is best to drink 15 minutes before travelling.
  • Spend time in the shade and avoid strenuous activity
  • Splash their faces and the backs of their necks with cool water

People with heart problems, breathing difficulties or serious illnesses may find their symptoms become worse in hot weather, so make sure 

  • they keep cool
  • check and keep up your medication 
  • take sensible precautions to prevent sunburn, particularly for children
