Jersey has joint second hottest year in 2023

Jersey's average temperature in 2023 was 13.34C (56.012F) - the equal second hottest on record

Jersey had its joint second hottest year on record in 2023, according to provisional data from Jersey Met.

The statistics showed the average temperature in 2023 was 13.34C (56.012F), the same average as 2014.

That put it behind the 13.56C recorded in 2022 (56.408F), the hottest on record, Jersey Met said.

The overall average was calculated from the average of each day’s maximum and minimum temperatures, it said.

Despite being the joint hottest year on record, provisional rainfall figures also showed 2023 was the wettest since records began at one weather station.

Jersey Met said a total of 1,352.9mm fell during 2023 at the Howard Davis Farm weather station, where records dated back to 1932.

At Maison St Louis Observatory, where records dated back to 1894, 1,074mm was recorded in 2023, the fifth-wettest for that site.

Mild nights

Paul Aked, Jersey Met's head of meteorology, said the island experienced many mild nights in 2023.

Mr Aked said: "Twenty-two nights during the year recorded a minimum temperature higher than the average daytime maximum for that day, 10 of those during a very mild December.

"September was the warmest for that month on record, June the second warmest, with October and December both being the fourth warmest, when compared with records dating back to 1894.

"They all contributed to the year being the equal second hottest on record."

Jersey Met said it would conduct further quality checks on the provisional figures over the coming weeks before final figures were confirmed.
