Hot weather warning

15 August 2025

​Temperatures are due to reach the high 20s this weekend and into next week. Some simple steps Islanders can take to stay cool during this hot spell include: 

  • avoid going outside during the heat of the day (midday to 6pm) 
  • leave strenuous activities for the evening when it is cooler 
  • take cold baths and showers 
  • drink plenty of water and avoid coffee and alcohol 
  • keep your home cool by closing curtains, opening windows and using fans 
  • wear a hat and loose light clothing, try to stay in the shade and carry water with you.

Director of Public Health, Professor Peter Bradley, said: “While the warm weather is enjoyed by most, extreme heat can cause harm to health including heat exhaustion, heatstroke, and dehydration, particularly to the most vulnerable in the community. I encourage all Islanders to take precautions and stay safe in the hot weather.”
