The Argus: Temperatures are set to soar in Brighton todayTemperatures are set to soar in Brighton today

The mercury hit 24C in Brighton with the Met Office predicting that temperatures will climb even higher today.

The weather service said the hot weather was due to an air mass from the south bringing up mild air, particularly impacting areas in the South East.

However, it is forecast that temperatures will slowly decline as the week goes on and the air mass moves, bringing in fresher air and temperatures closer to the average for this time of year.

Met Office forecaster Oli Claydon said: “We’ve got an air mass moving up from the south which is helping to bring some warm air with it and why we’re seeing some of the highest temperatures of the year.

“It’s the same reason why we’ve been seeing the thunderstorms over the past few days as well. That will change as we go through the week, with fronts moving in and bringing ever so slightly fresher air.

“One thing to note is that the particular high of 26C is quite confined to the south east.”

The previous highest temperature recorded so far this year was 23.6C (73.48F) in Faversham, Kent, on May 6.
