Mild start to November sees temperature records broken

Mild Start to November Breaks Temperature Records in the UK

The beginning of November 2025 saw an extraordinary series of new high daily minimum temperature records across the UK, with numerous weather stations reporting significant warmth. This continued a trend from October, which was already warmer than average.

October’s Warm Weather Sets the Scene

October 2025 recorded a provisional mean temperature 0.7°C above the 1991–2020 average. Scotland and Northern Ireland experienced slightly higher temperatures compared to other regions.

Warm Air Flow Causes Unusually High Overnight Temperatures

As November began, warm air moved from the south over the UK. This southerly airflow, combined with overcast skies, trapped heat overnight, resulting in notably high daily minimum temperatures.

Understanding Daily Minimum Temperature

The daily minimum temperature is the lowest temperature logged over a 24-hour period from 09:00 UTC one day to 09:00 UTC the next. This minimum usually occurs in the early morning hours, and the recorded date corresponds to the end of this period.

Record-breaking Bonfire Night 2025

“Temperatures overnight only dropped to 14.4℃ at Teddington in London, provisionally making it the mildest Bonfire Night on record.”

This exceptional warmth during nighttime hours highlights changing weather patterns and increasing temperature records.

Summary: Early November 2025 brought unprecedented warmth to the UK, breaking longstanding overnight temperature records amid a continuing trend from a warmer-than-average October.
