This page presents Belarus's climate context for the current climatology, 1991-2020, derived from observed, historical data. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. You can visualize data for the current climatology through spatial variation, the seasonal cycle, or as a time series. Analysis is available for both annual and seasonal data. Data presentation defaults to national-scale aggregation, however sub-national data aggregations can be accessed by clicking within a country, on a sub-national unit. Other historical climatologies can be selected from the Time Period dropdown list. Data for specific coordinates can be downloaded for in the Data Download page.
Average annual temperatures in Belarus increase from the higher latitudes in the northeast (4.5°C) to the lower latitudes in the southwest (7.0°C). Average temperatures in January (the coldest month) increase in the same direction from -8.0°C (in the northeast) to -4.5°C (in the southwest), while average temperatures in July (the warmest month) increase from 17.0°C (in the northwest) to 18.5°C (in the southeast). National annual precipitation averages 600-700 mm; with ranges from 300 mm in dry years to 1,000 mm in humid years. Approximately 60% of annual precipitation occurs in the warm season.
- Belarus has experienced a clear warming trend over the past century. Six out of seven highest positive temperature anomalies recorded in the past century have occurred in the in the past 20 years.
- Between 1988 to 2007, average warming nationally was 1.1°С, with the greatest increases in the northern regions and during the winter months.
- Between 1998-2007, in the capital city of Minsk, the duration of winter decreased by 10-12 days and average winter air temperature increased by 1.5-1.7°С. This has resulted in earlier loss of snow cover and earlier vegetation period (almost two weeks earlier than the long-term annual average rate).
- Over the past 30 years, there has been no significant change in precipitation nationally, however regional variations are notable. Precipitation has been increasing in north, north-eastern and some central regions, while reductions have been occurring in south and western regions.
- Records show that the number of days annually with stable snow cover varies from 75 in the southwest to 125 in the northeast. In the past decade, the duration of stable snow cover has been decreasing across the whole country.
