The pressure is on, no, not your blood pressure… depending on family arrangements of course! The major models have largely aligned on a scenario where the current mild, unsettled Atlantic weather breaks down just before Christmas, replaced by a large area of High Pressure.
This brings a “classic winter” feel: mostly dry, sunny, and cold, but with a biting easterly wind that will make it feel significantly chillier than the thermometer reads.
Christmas Eve (Wednesday, 24 Dec)
- General: A settled day for almost everyone. Dry conditions with variable cloud and sunny spells.
- Temperature: Highs of 5–8°C, but temperatures will drop sharply after dark.
- Hazards: As skies clear overnight into Christmas morning, widespread frost is expected inland, along with patches of freezing fog.
Christmas Day (25 Dec)
- General: A bright, crisp start for most.
- Wind: A brisk easterly wind will pick up, affecting the southern half of the UK and the east/south coasts of Ireland the most. This will add a significant wind chill.
- Snow Chances (“White Christmas”):
- Widespread Snow: Unlikely. There is no “beast from the east”
- The Exception: There is a small chance of light wintry showers or flurries affecting the far South of England (Cornwall, Devon, South Coast) and potentially the East Coast of Ireland due to the wind blowing off the sea. Any snow is unlikely to settle. No impacts expected.
- Temperatures:
- Highs of 4–7°C (feeling close to freezing in the wind).
Looking further ahead, the high-pressure system dominating Christmas is expected to remain stubbornly in charge through Boxing Day and into the New Year, prolonging the spell of cold, settled weather. As we head towards New Year’s Eve, the easterly winds may ease slightly but prolonged sharp frosts and freezing fog patches could still linger all day in sheltered spots.
The majority of the UK will stay dry and crisp for the start of 2026.
