In a new study, the Met Office also concluded that human-induced climate change made the record-breaking temperatures around 160 times more likely.
Without climate change, it was estimated that such temperatures would only be experienced in around one in 500 years, but it is now likely they will recur every three to four years under current climate conditions.
The full annual UK mean temperature data for 2022 resulted in a provisional figure of 10.03°C, the highest yet in records dating back to 1884. This made 2022 0.89°C above the 1991-2020 average and 0.15°C higher than the previous record of 9.88°C set in 2014.
Dr Nikos Christidis, Met Office climate attribution scientist, said: “We also used climate models to project how often this sort of temperature could be recorded in the future. It was possible to calculate that by the end of the century, under a medium emissions scenario (SSP2-4.5), a UK average temperature of 10°C could occur almost every year...
