Mild Start to November Breaks Temperature Records in the UK

The beginning of November 2025 has seen numerous daily minimum temperature records shattered across the UK, with many weather stations reporting unusually warm nights. This streak of overnight warmth follows an October that was already warmer than usual, highlighting the meteorological factors contributing to these new records.

October 2025 Weather Overview

October's weather set favorable conditions for the warm start to November. The provisional mean temperature for October was 0.7°C above the 1991–2020 average. Scotland and Northern Ireland experienced slightly higher temperatures than other parts of the UK during this period.

Warm Air Flow and Cloud Cover

As November began, a southerly flow brought warm air across the UK. This weather pattern, combined with cloudy skies, trapped heat overnight, resulting in unusually high daily minimum temperatures.

Note: Daily minimum temperature refers to the lowest temperature recorded in a 24-hour period from 09:00 UTC to 09:00 UTC the following day. The date assigned corresponds to the end of this period, as the lowest temperatures usually occur in the early morning.

Record-breaking Bonfire Night 2025

Bonfire Night on November 5-6, 2025, was exceptionally mild. Temperatures only dropped to 14.4℃ overnight at Teddington, London, provisionally setting a new record for the warmest Bonfire Night.

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

Early November 2025 brought unprecedented overnight warmth across the UK, fueled by a warm October and persistent southerly air flow, culminating in record-breaking temperatures on Bonfire Night.
