Drought Expected And Heatwave Possible

Jersey is likely to be in an official drought later this month and the island could experience a heatwave too.

Jersey Met is predicting that temperatures will build steadily throughout the coming days, with the weekend possibly reaching 30°C.

The maximum daily temperature has to exceed the average maximum temperature by 5°C for six consecutive days to meet the heatwave criteria.

Forecasters are not expecting any rain over the next seven to ten days, so it's likely that the island will be in an official drought from Saturday 16 July.

So far this year, the island has recorded 25% less rainfall than average.

Droughts have been recorded 128 times in Jersey since rainfall records began at Maison St.Louis Observatory in 1894.

A drought is defined as a period of 15 consecutive days with no measurable rainfall.

The heat is also affecting the temperature of the sea, which has remained above average throughout 2022.

If that continues until the end of the year, it will be the first time it happens.
