December is the start of the cold winter season in Prague with chilliness in the air and darkness in the skies. The average temperature is in the range of a cold -2.8°C (27°F) to 2.2°C (36°F), and prevailing westerly winds accelerate the frosty conditions.
The days remain below freezing as a moderate 160mm (6.3") of snowfall covers the ground in white. The sun hardly smiles on the landscape as the daily sunshine lasts for 1.5 hours during the 8-hour, shortest days of the year.
It takes a brave heart tourist to weather the cold with the warmest winter coats in the closet.
