Very high temperatures may lead to impacts on Thursday.

What should I expect?

  • Adverse health effects are likely to be experienced by those vulnerable to extreme heat
  • The wider population is likely to experience some adverse health effects including sunburn or heat exhaustion (dehydration, nausea, fatigue) and other heat-related illnesses
  • Some changes in working practices and daily routines likely to be required
  • Some heat sensitive systems and equipment may fail, with the potential for some power cuts and the loss of other services to some homes and businesses.
  • More people are likely to visit coastal areas, lakes and rivers leading to an increased risk of water safety incidents
  • Some delays to road, rail and air travel are possible, with potential for welfare issues for those who experience prolonged delays

What should I do?

Keep yourself safe by following these simple steps to reduce the likelihood of the heat making you feel unwell; drink plenty of fluids, keep out of the sun and avoid any exercise between 11am-3pm when the sun is strongest and close curtains in rooms that face the sun. If you are going out take water with you, stay in the shade, wear sunscreen and a wide brimmed hat. Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary. If using public transport, there are many simple things you can do to keep yourself safe; carry water with you, take a small hand-held battery powered fan, if you feel unwell get off at next stop for some fresh air, dress in light fabrics in light colours to help stay cooler, keep an eye on fellow passengers for signs they may be struggling. Help to protect vulnerable people that you know including older people, those with underlying conditions and those who live alone; they may need support to keep cool and stay hydrated. If you are worried about your health, or that of somebody you know, ring NHS 111. Keep yourself safe whilst enjoying the water in this weather by following these simple steps: enter the water gradually, avoiding jumping or diving straight in, to reduce your risk of cold water shock, go to a lifeguarded beach or a supervised swimming area, and, if you, or anyone else, get into difficulty in the water, float on your back. People cope better with power cuts when they have prepared for them in advance. It's easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items. Stay up to date with the weather forecast for your area and follow any advice from emergency services and local authorities.
