Understanding the capital’s weather patterns becomes crucial for planning activities, from Christmas shopping along Oxford Street to visiting seasonal markets and outdoor events.

Maximum temperature 11 °C is expected in the coming days, with minimum temperature 4 °C during overnight periods.
There are normally 1 hour of bright sunshine each day in London in December, and there are usually 14 days with some rain in London in December.

What This Means for Londoners and Visitors
The weather conditions present both challenges and opportunities. Often windy, especially in the north and west where there is potential for a spell of very strong winds to develop for a time early next week, generally mild with any overnight frost patchy and mainly in the north. For those planning festive activities, indoor attractions such as museums and galleries offer excellent alternatives during rainy spells.
Looking ahead, there are signs that conditions may become less disturbed heading towards the Christmas period, with the potential for high pressure to build bringing drier conditions, with the risk of overnight frost and fog patches increasing. This shift could provide clearer skies for the holiday period, though visitors and residents should remain prepared for typical unpredictable British weather and carry appropriate clothing for all conditions.
