The Met Office has indicated that while a white Christmas is technically possible this year, significant snowfall is unlikely. The south coast of England, particularly South Devon and Cornwall, has the greatest chance of seeing an 'odd wintry flurry', according to Met Office meteorologist Marco Petagna. However, the chance of noteworthy snowfall is only around 10%, meaning festive snowball fights are improbable.
High pressure is building across the UK, bringing drier and more settled weather for many, despite some areas experiencing showers. A strong easterly breeze will make it feel colder, though temperatures are expected to be typical for the season, with Christmas Day highs of 7°C and lows of -3°C or -4°C. The Met Office notes that a white Christmas technically requires only a single snowflake to fall anywhere in the UK, but lying snow is much rarer.
According to the Royal Meteorological Society, a snowflake has fallen on Christmas Day 54 times in the past 66 years at some location in the UK. Every year since 2020 has been deemed a white Christmas, though snow has not settled in recent years. A thick blanket of snow on Christmas Day has occurred only four times since 1960: in 1981, 1995, 2009, and 2010, with 2010 recording snow on the ground at 83% of stations.
The rarity of festive snow cover is partly attributed to climate change, with Met Office data showing UK Decembers have become warmer in recent decades, reducing the overall chance of snowfall on Christmas Day. However, natural variability means cold and snowy spells can still occur, and most snow days in the UK happen between January and March.
