And this is not only snow, but also unpleasant cold rain and drizzle. The average precipitation in the last month of the year is 13.4 mm.
The average temperature for the month is +4 °C during the day and +1 °C at night. It is difficult to say when the weather is better: at the beginning or end of December, as the entire period is very changeable.

The only thing that is stable is the almost complete calm, but it is not windy in the city throughout the year.
