According to long-term observations (1948-2010) by Kamenyuki meteorological station located on the territory of the forest, the average annual air temperature is 6.80 C. The warmest month is July (17.80С), the coldest month is January (-4.40С). The maximum and the minimum temperatures reach values of 36.4° and -40.1°, respectively.
Seasonal snow cover lies no longer than 50-60 days. In one fifth of winters, it is not observed at all. The period with the air temperature below 0°C lasts about 100-110 days.
A stable period with an average daily temperature above 0°C comes about March 19 and lasts until the end of November – the beginning of December, making about 260 days.
Spring frost ends at the end of April – the beginning of May (mean date is May 6, extreme date is April 19 and June 2). The duration of the period without frost is 135-170 days.
Average yearly precipitation is 659 mm, including about 430 mm in the warm period (April-October).
The total incoming of solar radiation is about 98 kcal / cm2.
With high heat availability, the area is characterized by a deficit of air humidity, the average index of which in May-July is 6.7-6.8 mill bar. The humidity factor for the warm period is 0.8, which is the lowest value on the territory of the Republic of Belarus and indicates an unbalance between the evaporating capacity and the amount of rainfall.
In general, the climate of the forest is close to Central European. The dynamics of soil-forming processes and peculiarities of flora and fauna support that statement.
