Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.

How busy it gets

December: quiet. Busiest from May to July; quietest from October to December.

Public holidays in December

Holidays crowd a place out and push fares up around them; they count toward the crowd score above.

What to pack

  • A proper coat, hat and gloves: nights average -10°C.
  • A packable rain jacket for the 11 or so rainy days.
  • Humidity averages 79%; breathable fabrics dry faster.

Each line is a threshold over the ten-year figures above, not advice from anywhere else.
