December 2025, as predicted both in my Winter Forecast & December Outlook was mild and wet with frequent lows and fronts affecting the NW of Europe including UK & Ireland. The southwest to northeast storm track kept the UK and Ireland on the warm, moist side of the ridge-trough couplet and higher pressure over Europe slowed eastward progress of systems which resulted in higher rain amounts frequently.

UK Stats/Highlights
December 2025: Provisional statistics
The final month of the year has concluded with just over average rainfall, warmer than average temperatures and above average sunshine for the UK.
The UK provisional mean temperature was 5.8°C – which is 1.6°C above the long-term meteorological average.
Unsettled conditions persisted for the first few weeks of December and by the 16th, the UK had provisionally recorded 75% of its average monthly rainfall. Several counties, including West Glamorgan and Cornwall had recorded over 100% of their average December rainfall.
The second half of December was drier however, resulting in only slightly above average rainfall for the month overall (101%). England and Wales were both wetter than average – 114% and 115% respectively.
Sunshine overall was above average at 108% for the UK, with Wales and southwest England particularly sunny (126% of average for Wales). There was also a clear north/south divide in England, with the north recording 85% of its December average and the south 123% in comparison.

9 Out of 10: Good December Prediction
The Verdict
I suspect average to above average temps/precip for UK, Ireland, W Europe as we are likely milder through at least the first half, Colder Christmas/New year possible.
