A dramatic shift in the weather is on the horizon for London, as an Arctic chill prepares to sweep across the capital this week. This sudden cold snap marks a stark contrast to the unseasonably mild conditions that have dominated the winter of 2025 so far.
A Sharp Drop in Temperature
Following the departure of Storm Claudia, a frigid air mass from the Arctic will cause temperatures to plummet. Londoners have enjoyed a remarkably warm season, with this year's Bonfire Night recorded as the warmest ever. Many have avoided heavy winter woollies and delayed turning on the heating, but that period of respite is officially over.
This week, the mercury will struggle to climb above 9C at its peak. The capital is bracing for its coldest day of the winter so far on Thursday. The Met Office forecasts that while the actual temperature will drop to 5C, it will feel more like a biting 2C due to wind chill. Overnight conditions will be even harsher, with temperatures around 2C but feeling as low as -2C or -3C.
Will London See Snow This Week?
The dramatic drop in temperature inevitably raises the question of snowfall. Despite the deep freeze, it is not expected to be quite cold enough for proper snow to settle in London during this period.
However, the Met Office has issued warnings for widespread overnight frosts between Wednesday and Friday. According to BBC Weather, the closest London will get to wintry precipitation is through sleet showers, expected from around 6am to 9am on Thursday. For those hoping for a white blanket, the possibility of snow is higher in more northern parts of the UK.
Staying Informed on London's Weather
This cold spell serves as a clear indication that winter has truly arrived in the capital. Residents are advised to take necessary precautions against the frost and biting wind chill. While snow remains unlikely for now, the forecast underscores the unpredictable nature of British weather as we move deeper into the season.
