London Christmas Day 2025 Weather: Hour-by-Hour Forecast Reveals Grey Skies
London's Christmas Day Forecast: Overcast and 8C High

London is set for a grey and overcast Christmas Day this year, with the latest forecasts ruling out any chance of a white Christmas for the capital.

A Cloudy Christmas for the Capital

Instead of festive snowfall, thick grey clouds will blanket the city's skies throughout Thursday, December 25th, 2025. The Met Office indicates that while the day will be cold, the iconic snow many hope for is not expected to fall in London.

The day will begin chilly, with early morning temperatures around 5 degrees Celsius. As Londoners unwrap their presents, the mercury will slowly climb, reaching a peak of approximately 8°C by 2pm.

Detailed Hour-by-Hour Outlook

The forecast provides a clear timeline for the day's conditions. Sunrise is scheduled for 8.05am, revealing the dominant cloudy skies. By 11am, temperatures will have risen to around 7°C under continued cloud cover.

The warmest part of the day arrives in the early afternoon, with the temperature peaking at 8°C at 2pm. The overcast conditions will persist, with the sun setting early at 3.56pm. As darkness falls, the temperature will drop back to 6°C by 7pm and is expected to remain steady at that level throughout the evening and overnight.

A Dry but Gloomy Festive Day

In summary, Londoners planning outdoor walks or family gatherings should prepare for a dry but distinctly gloomy December day. The thick cloud will dominate from sunrise until after sunset, with a modest temperature range between 5 and 8 degrees Celsius.

While it may not be the picture-postcard Christmas some envision, the forecast suggests a typical British winter's day—cold, grey, but thankfully free from heavy rain or snow disruptions. The consistent temperature into the evening may at least offer some respite for those travelling to visit loved ones after the daytime festivities.
