The winter period, from December to February, is characterized by frequent precipitation, predominantly in the form of snow or wet snow, as average temperatures fluctuate around zero.

However, their intensity is usually low, and often it is just a light drizzle or calm snowfall.

In summer, especially in July, a peak in humidity is observed: it rains approximately 13 days a month, and the volume of precipitation reaches its annual maximum. In the warm season, including June and August, rains more often take the character of short-term downpours that quickly refresh the city after the midday heat.

When packing for Bydgoszcz, first of all, ensure you have comfortable flat shoes, as you will be walking a lot on the cobblestone streets of the Old Town and picturesque embankments. The weather in this region of Poland can be quite changeable, so a universal tip for any season is to dress according to the layering principle. This approach will allow you to feel comfortable both during a cool morning and in the midst of a sunny day, simply by removing or adding layers of clothing.

If your trip is planned for the period from November to March, be sure to take a warm windproof jacket, hat, scarf, and gloves. Winters here are moderately cold, with an average temperature around 0...+2°C, but due to humidity, the air may seem colder. For long walks in the fresh air during winter months, a set of thermal underwear would also be useful.

In summer, pleasant warm weather settles in Bydgoszcz, when the thermometer often rises to 23–24°C. At this time of year, light clothing made of natural fabrics and sunglasses will come in handy. However, considering the precipitation statistics (rains are possible on average 10–13 days a month year-round), a compact umbrella or a light raincoat will become your faithful companions in any season, protecting against sudden showers during excursions.
