The coldest month is January, when the average temperature hovers around -1.2°C, and night frosts can drop to -3.2°C and lower.

Summer in Bialystok is typically pleasantly warm rather than stiflingly hot. Daily highs in July and August average 23-24°C. This is the ideal time for long walks and exploring the city. It is worth paying attention to the noticeable difference between day and night temperatures: even in the warmest months, nights can be cool, with temperatures dropping to 13-14°C, so a light jacket or sweater might come in handy for evening outings.

Winter in the city is authentic, frosty, and snowy. From December to February, the temperature remains steadily around zero or drops lower, especially at night. The shoulder seasons—spring and autumn—are characterised by smooth transitions. In spring, the temperature gradually rises, reaching a comfortable 18°C during the day in May, and in autumn it declines just as smoothly, preparing the city for the arrival of winter. The greatest daily temperature fluctuations are observed in the spring and summer months.

In Bialystok, precipitation is distributed fairly evenly throughout the year, so there is no clearly defined dry or rainy season here. However, the intensity and frequency of precipitation vary from month to month. The greatest amount of precipitation by volume falls in July, while the "driest" months, with the lowest volume, are March and November.

The winter months, especially January and December, are characterised by frequent precipitation. Given the average sub-zero temperatures, this is predominantly snowfall. January holds the record for the number of days with precipitation—averaging 16 days. Rain is also common in summer. In July, the wettest month, there are about 15 rainy days, which can indicate short but intense summer showers.

Spring and autumn are transitional periods. March stands out as the month with the lowest frequency of precipitation, with only about 9 days, making it one of the driest of the year. In other months, the number of days with precipitation ranges from 10 to 12, providing the city with moderate moisture without prolonged droughts or excessively rainy periods.

When planning a trip to Bialystok, it is worth remembering its temperate climate with distinct seasons and fairly frequent precipitation throughout the year. The key principle when packing your suitcase is layering. Regardless of the time of your visit, be sure to take comfortable waterproof shoes for long walks around the city, as well as a compact umbrella or raincoat, since rainy days happen even in the warmest months.

For a winter trip (December to February), when temperatures often drop below freezing, a warm jacket or down coat, hat, scarf, and gloves are necessary. Thermal underwear and warm socks will not go amiss. In summer (June to August), the weather is usually warm and pleasant, so light clothing is suitable: T-shirts, dresses, and shorts. However, evenings can be cool, and July has the highest amount of rainfall, so it is worth grabbing a light cardigan or windbreaker. Sunscreen and sunglasses will also be useful for clear days.

Spring (March to May) and autumn (September to November) are times of changeable weather. The ideal solution would be a combination of T-shirts, jumpers, and a mid-season jacket or trench coat. Such a set will allow you to easily adapt to temperature changes throughout the day, whether it be a sudden cold snap or, conversely, warm sunshine.
