Mild Start to November Breaks Temperature Records in the UK

The beginning of November 2025 has seen an extraordinary series of new high daily minimum temperature records across the UK, with numerous weather stations reporting unusual warmth overnight. This streak of warm nights follows an October that was already notably warmer than average, highlighting significant meteorological changes.

October 2025 Weather Overview

October 2025 recorded a mean temperature provisionally 0.7°C above the 1991–2020 average. Scotland and Northern Ireland experienced slightly warmer conditions compared to the rest of the UK, setting a warm baseline ahead of November.

Warm Air Flow and Its Effects

As November began, a southerly flow of warm air moved across the UK. This, combined with mostly cloudy skies, helped trap heat overnight, resulting in unusually high daily minimum temperatures. The daily minimum temperature is the lowest temperature observed over a 24-hour period from 09:00 UTC one day to 09:00 UTC the next. The date recorded is the end of this period, as the coldest time usually occurs in the early morning hours.

The previous record for this night was 13.9°C at Gordon Castle, Scotland, in 1938.
