Jersey set for heatwave as island braces for tropical nights and soaring temperatures

Residents across Jersey are being urged to prepare for a spell of extreme heat, with forecasters warning that temperatures could climb into the mid-30s over the coming days.

Jersey Met has predicted highs of around 31C on Sunday, with temperatures potentially rising further to 34C or above on Monday. The island is also expected to experience “tropical nights”, with overnight temperatures remaining above 20C on both Sunday and Monday.

Public Health Jersey has issued advice for people to stay safe during the hot weather, recommending that residents avoid being outdoors during the hottest part of the day and delay strenuous exercise or activities until temperatures begin to fall.

People have been encouraged to drink plenty of water, while limiting drinks such as coffee and alcohol, which can contribute to dehydration. Health officials also advised taking cool showers or baths to help manage the heat.

The warning follows a period of unusually warm weather in May, when Jersey recorded its first five-day run of temperatures reaching at least 30C. The island’s highest temperature during that spell reached 34.2C on Tuesday 26 May.

Further advice includes keeping curtains and blinds closed during the hottest periods to block out heat, opening windows when temperatures are cooler, and using fans where possible.

Residents are also being reminded to protect themselves from the sun by wearing hats, choosing loose, lightweight clothing, and applying sunscreen with a minimum SPF of 30.
