UK Braces for Warmest Day of 2025 as Spring Equinox Arrives

Temperatures are set to reach up to 21C in London on Thursday, surpassing recent highs, with cooler weather expected to follow by the weekend.

The UK is experiencing an unseasonably warm spell, with temperatures rising steadily since midweek.
Thursday, March 20, is forecast to reach highs of 21C in London, potentially making it the warmest day of the year so far.
The warm weather coincides with the spring equinox, marking the official start of the new season.
Parts of the UK, including southeast England, the Midlands, and Wales, may see temperatures higher than popular Mediterranean destinations like Corfu and Ibiza.
The warm spell will be brief, with cooler and unsettled conditions, including rain, expected to return by Friday and continue into the weekend.
