The Vienna weather in December is very cold and wintery. Even though you’ll need to wrap up warm, Vienna’s great fun to explore in December.
The weather in Vienna in December produces a daytime high temperature of just 2°C, the low temperature can reach -2°C and it can be even lower at night. The sun sets at 4pm in Vienna for most of the month. The wintery climate produces 50mm of rain, on average, and a little of this will fall as snow and sleet.
