The UK has recorded a temperature above 35C for three consecutive months this year, something that would have been unusual just once a year in the 20th Century, according to the Met Office.
In their latest report summarising the state of the UK’s climate in 2025, they say that “climate extremes are becoming the new normal” in the UK.
The climate we had in the 20th Century has “now gone”, according to the report’s lead author Mike Kendon.
Annual average temperatures in the UK have increased with the latest 10 year period now 1.33C warmer than during 1961-1990 period.
The last four years are in the top five warmest on record for the UK.
But Kendon says what is “particularly concerning” is how this warming has led to more temperature extremes.
The number of days over 30C has quadrupled in areas such as Greater London and the hottest day of the year has warmed by 4.5C.
The UK is now coming to expect temperatures of 35C during hot spells in our summers going forward, he said.
“Every year is adding to the body of evidence showing climate change in the UK,” he added.
