SATURDAY was the seventh hottest June day in Jersey since records began.
Temperatures reached a sweltering 32.4°C while hundreds of participants attempted the Island Walk.
Friday’s high of 31.5°C makes it the twelfth highest temperature recorded in June.
Records began in 1894.
Temperatures dropped on Sunday and are expected to stay in the 20s through this week.
The government has issued guidance on how Islanders can stay cool during hot weather, including:
- Avoiding going outside during the heat of the day (midday to 6pm)
- Leaving strenuous activities for the evening when it is cooler
- Taking cold baths and showers
- Drinking plenty of water and avoiding coffee and alcohol
- Keeping your home cool by closing curtains, opening windows and using fans
- Wearing a hat and loose light clothing, and trying to stay in the shade and carrying water with you
Public Health director Professor Peter Bradley said: “While we welcome the warm weather, extreme heat can cause harm to health including heat exhaustion, heatstroke, and dehydration.”
Jersey experienced its seventh-hottest year on record last year, according to Jersey Met.
The four hottest years on record have happened over the past 11 years: an average of 13.23°C in 2020, 13.34°C in both 2014 and 2023, and the record mark from 2022 of 13.56°C.
