Belarus is known for its cold winters and frequent snowfall. In fact, the country experiences an average of 75 to 125 days of snow each year, with falls ranging from 15 to 30 centimeters. The temperature in Belarus during winter is usually below freezing (0 °C or 32 °F) even during the day for a few months. In some regions of Belarus, snow covers the ground for about four months. The coldest periods are those in which the Siberian Anticyclone reaches the country, though it has happened more rarely in the last decades. During these periods, the temperature can drop to -30 °C (-22 °F), but in the worst winters of the past century, they could drop to as low as -40 °C (-40 °F). In spring, the temperatures increase rapidly, and the thaw occurs between March and April. Summer in Belarus is quite warm, and unlike in winter, it tends to become progressively warmer as you move from the north to the south. Autumn is a short season, during which the temperature decreases rapidly, and the weather quickly becomes cloudy, rainy and foggy. Belarus has an average annual rainfall of 600-700 mm, with 70% of the rain falling from April to October.

In conclusion, Belarus experiences frequent snowfall and cold temperatures during winter, with the coldest periods occurring when the Siberian Anticyclone reaches the country. Spring brings a rapid increase in temperature and thaw, while summer is quite warm and tends to become progressively warmer as you move from the north to the south. Autumn is a short season, during which the temperature decreases rapidly, and the weather quickly becomes cloudy, rainy and foggy.
