Overview
- December 2025 is currently tracking as the second-warmest December since 1881, with several outlets noting the month could challenge for first place if mild conditions continue.
- A large, persistent high-pressure system over Europe is suppressing Atlantic storms, keeping most regions dry and limiting prospects for lowland snow before Christmas.
- The DWD maintains local alerts for dense fog, poor visibility, frost and icy patches in parts of Germany, with examples cited in Bavaria and North Hesse.
- Forecast models diverge for the period after Christmas: some GFS runs suggest an Arctic intrusion with severe night frost and snow, while ECMWF and newer runs are more cautious.
- Short-term outlooks call for stubborn lowland fog with sunnier breaks in higher terrain and temperatures often near 5–10°C, with the best chances for holiday snow confined to higher elevations.
