The start of November 2025 has brought a remarkable series of new high daily minimum temperature records across the UK, with dozens of weather stations reporting notable warmth.
This exceptional run of overnight warmth follows an October that was already warmer than average, and the latest data highlight the evolving meteorological context behind these new records.
October’s mild lead-in
The UK’s weather pattern in October 2025 set the stage for November’s record-breaking temperatures. The mean temperature for the month was provisionally 0.7°C above the 1991–2020 average, with Scotland and Northern Ireland experiencing slightly warmer conditions than the rest of the country.
As November began, a flow of warm air from the south swept across the UK. This southerly pattern, combined with cloudy skies, helped trap warmth overnight, leading to unusually high daily minimum temperatures.
Daily minimum temperature is the lowest observed temperature for a 24 hour period between 0900UTC and 0900UTC. The date to which this is assigned is the end date of this period. This is because the lowest temperature is typically - although not always - recorded in the early hours of the morning.

- North and Midlands: Yorkshire, Staffordshire, Cumbria, and Humberside also reported new records, highlighting the widespread reach of the mild air.
- Scotland and Northern Ireland: While stations in these regions didn’t set new records, the overall trend was for warmer-than-average nights.

Meteorological context
The mild spell was driven by a combination of factors. Warm air from the south, persistent cloud cover, and a lack of cold continental air all contributed to the overnight warmth. The North Sea, only slightly cooler than average, played a role in moderating temperatures, especially in eastern areas. As high pressure builds and winds turn more to the southeast, temperatures are expected to cool, particularly in the east. However, the continent is not especially cold at this time of year, so temperatures are likely to return to average levels for November, rather than dropping sharply.
Looking ahead, model ensembles suggest a gradual decline in temperatures, with the most noticeable cooling in eastern areas. Further west, the picture is less clear, as low pressure systems could bring milder air from the south or southwest. After an exceptionally mild spell, conditions are returning to something closer to normal for the time of year.
