On Tuesday the temperature reached 16.4C (61.5F) in Epping Forest but temperatures could be higher on Wednesday. More sunshine in eastern England and a southerly breeze will make all the difference and here temperatures are expected to reach 17-18C (63-64F).
Further north and west there will be more cloud and some rain, but temperatures will still be above average.
To put this warmer weather into context – the last time the temperature reached 18C was 13 November 2025, and the record for February is 21.2C (70.2F) on 26 February 2019 at Kew Gardens.
Wednesday is likely to be the peak of the warmth this week with temperatures back to near average on the last day on February.
