From December to February, Germany, Austria, Czechia and Hungary hover around 0°C, with some sub-zero days; Paris and London are damp and windy at about 3–8°C.
- Dress in layers: thermal base, sweater or fleece, padded jacket or long wool coat.
- Keep hands, head and neck warm: touchscreen gloves, beanie, scarf.
- Waterproof, non-slip shoes and wool socks.
- Indoors, trains and museums are warm, so choose a coat that's easy to take off.
- Short days: it gets dark around 4–4:30 pm, so do outdoor sightseeing in the morning.
Note: standing at an evening market feels much colder than walking; bring heat packs.
