Jersey Set for Record-Breaking Heat as Temperatures Could Reach 37°C

Jersey is preparing for an intense spell of hot weather, with forecasters predicting temperatures could climb to 37°C on Tuesday and Wednesday.

The island is facing another major heatwave less than a month after a record-breaking warm spell in May, as extreme temperatures continue across Europe, with parts of France already seeing temperatures above 40°C.

A period of high heat has now moved across the region, with an amber warning for extreme heat issued in parts of southern Britain.

Jersey Met has forecast temperatures of 34°C for Monday, which would exceed the previous June record of 33.4°C set on the final day of June last year.

However, the heat is expected to intensify, with highs of 37°C predicted on both Tuesday and Wednesday. The highest temperature ever recorded in Jersey was 37.9°C on 18 July 2022.

The current heatwave began on Sunday and is expected to last around five days. Officially, a heatwave is defined as three consecutive days with temperatures above 28°C.

Although overnight temperatures did not reach the level required for a tropical night, conditions are expected to become increasingly uncomfortable, with minimum temperatures of around 22°C tonight and 24°C tomorrow — warmer than the average daytime temperature for this time of year.

The hot weather will continue into Thursday, with temperatures forecast to reach 33°C, before cooling to the mid-twenties over Friday and Saturday.

Meteorologist Alex Deakin warned the added humidity could make the heat feel even more intense than the previous hot spell and increase health risks, particularly for older people and young children.

Residents are being advised to stay out of the strongest heat between 11am and 3pm, drink plenty of water, avoid strenuous activity during the hottest part of the day, and take steps to stay cool.

Health guidance includes keeping curtains closed, allowing breezes through open windows, using fans where possible, wearing light clothing and hats, and applying sunscreen with at least SPF 30.

Schools across Jersey are also monitoring classroom temperatures, with some preparing to close early if conditions become too difficult for pupils and staff.

Islanders are being urged to take care over the coming days as Jersey experiences one of the hottest spells of weather in recent years.
