Weather in Bratsk

Stay up to date with the current weather conditions in Bratsk. In this section, you will find the latest data, forecasts, and visual charts.

Bratsk is characterized by a sharply continental climate, which means significant temperature fluctuations throughout the year. Prepare for harsh, frosty winters and a short but relatively warm summer. The city does not experience high rainfall, with precipitation levels remaining low all year round.

Winter in Bratsk is long and cold, beginning in November and lasting until March, with average temperatures well below freezing, especially in January and December. Summer, spanning June, July, and August, offers more comfortable conditions with pleasant warmth, as average temperatures rise to +16°C – +19°C. Spring and autumn are short transitional seasons with rapid shifts in temperature.

A key feature of the climate in Bratsk is the low precipitation, which is evenly distributed across the months and rarely exceeds 1–2 mm. Despite this, the number of days with precipitation can be quite significant, particularly in May, July, September, and November, indicating frequent but light precipitation, such as drizzle or light snow.

The annual temperature trend in Bratsk demonstrates the pronounced continental nature of the climate. January is traditionally the coldest month, when the average temperature drops to -20.3°C, and nightly lows can reach -23.9°C. July is considered the warmest month, with an average temperature of +18.9°C and daytime highs rising on average to +23.4°C. Thus, the annual range of average monthly temperatures is about 39 degrees, highlighting the dramatic climatic shifts.

The summer months in Bratsk – June, July, and August – bring pleasant, moderate warmth. In June, the average temperature is +16.2°C, with daytime highs around +21.5°C and nighttime lows around +10.9°C. July, as the warmest month, delights with an average temperature of +18.9°C, while the air can warm up to +23.4°C during the day and cool down to +14.5°C at night. August is slightly cooler than July, with an average temperature of +16.9°C. The summer period is characterized by noticeable diurnal temperature fluctuations, where the difference between day and night readings can exceed 10–12 degrees, so even after a warm day, the evening can be crisp.

Winter in Bratsk is distinguished by its severity and prolonged frosts. December opens the sequence of cold months with an average temperature of -18.5°C (minimum -21.6°C, maximum -15.3°C). January is the peak of winter: the average temperature reaches -20.3°C, nighttime frosts can drop to -23.9°C, and the daytime temperature rarely rises above -16.7°C. February slightly softens winter's grip but remains very cold with an average temperature of -17.5°C (minimum -22.0°C, maximum -13.1°C). Daily temperature fluctuations in winter are less pronounced than in summer but are still present, averaging 5–8 degrees.

Precipitation in Bratsk is characterized by its scarcity throughout the year, and there is no pronounced rainy season or, conversely, a dry period. The total amount of precipitation remains consistently low, amounting to just 1–2 mm per month. A slight, symbolic increase in precipitation volume is observed in the summer-autumn period – from July to September – when 2 mm falls. In other months, including winter, spring, and late autumn, the average precipitation level does not exceed 1 mm.

The nature of precipitation in Bratsk depends directly on the season and temperature regime. In the cold period, which covers the months from November to March, as well as partly October and April, when average temperatures hold steadily below freezing, precipitation falls mainly as snow. Given the extremely low monthly volume, this likely means frequent but light snowfall, possibly in the form of light snow pellets or frost. In the warm season, from May to September, when temperatures are positive, precipitation takes the form of rain. Again, due to the small amount, this usually involves non-intense, drizzling, or brief light rains.

If we consider the "wetness" of the months, July, August, and September have a slight advantage in actual precipitation amount (2 mm each). However, regarding the number of days with precipitation, the picture is somewhat different: September leads, with an average of 13 days with some form of precipitation. Precipitation is also observed quite often in May, July, and November (11 days each). The "driest" month in terms of rainy/snowy days is February, with only about 5. Overall, the climate of Bratsk is typified by frequent but very low-volume precipitation, which is important to consider when planning outdoor activities.

When planning a trip to Bratsk, it is important to choose your wardrobe correctly, considering the sharply continental climate with its significant temperature contrasts. Winter here is harsh and long; from January to March and November to December, average temperatures range from -7.4°C to -20.3°C, and minimums can drop even lower. Therefore, in the winter months, very warm outerwear (a down jacket or fur coat designed for severe frosts), thermal underwear, warm sweaters (wool or fleece), insulated trousers, a hat covering the ears, a voluminous scarf, and very warm gloves or mittens are absolutely necessary. Do not forget waterproof and insulated shoes with thick non-slip soles.

Summer in Bratsk is short but quite warm, especially in July, when the average temperature reaches +18.9°C, and daytime highs can rise to +23.4°C. For the summer months (June–August), light trousers, T-shirts, long-sleeved shirts for protection from the sun and cool evenings, as well as a light jacket or windbreaker, are suitable. Considering that even in summer, night temperatures can drop to +10.9°C (in June), the principle of layering will come in very handy. Despite the small amount of precipitation (1–2 mm per month), "wet days" happen quite often (9–11 days in summer months), so a light raincoat or umbrella may be useful. Comfortable walking shoes and sunglasses are mandatory.

The transitional seasons – spring (April–May) and autumn (September–October) – are characterized by rapid weather changes. In April, the average temperature is still around 0.6°C, while in May it is already +8.1°C. In autumn, the temperature also drops quickly: from +8.8°C in September to +1.3°C in October. During these periods, it is best to dress in layers: a T-shirt, sweater, and demi-season jacket (preferably wind- and moisture-proof). Waterproof shoes will also be relevant, as precipitation, although slight, can be in the form of rain or even wet snow, especially in April, October, and November. Regardless of the season, always take comfortable walking shoes with you.
