Mild Start to November Sees Temperature Records Broken

The start of November 2025 has brought an exceptional wave of mild nights across the United Kingdom, with numerous weather stations logging record high daily minimum temperatures. These readings follow an already warm October, highlighting unusual meteorological conditions this autumn.

Unseasonably Warm October Set the Stage

October 2025 finished provisionally 0.7°C above the 1991–2020 average. Scotland and Northern Ireland were slightly warmer compared to other regions. This trend prepared the ground for the exceptional warmth observed in early November.

Southerly Airflow and Cloudy Nights

As November started, a persistent flow of mild air from the south swept across the country. Combined with widespread cloud cover, this pattern limited heat loss during the night, resulting in record-breaking minimum temperatures.

Definition of Daily Minimum Temperature

The daily minimum temperature represents the lowest value recorded within a 24-hour period between 0900 UTC and 0900 UTC the next day. This reading is usually taken during the early morning hours.

Record-Breaking Bonfire Night

On Bonfire Night 2025, temperatures in Teddington, London, fell only to 14.4°C, making it provisionally the mildest Bonfire Night on record. The previous record for the night of 5–6 November was 13.9°C, recorded at Gordon Castle, Scotland, in 1938.

Such mild nighttime temperatures for early November emphasize the unusual warmth seen this season and point to broader climatic shifts influencing UK weather patterns.
