In Gdansk, precipitation is distributed relatively evenly throughout the year, without a pronounced rainy season or drought period. However, the amount of rainfall and the number of rainy days vary from month to month. Overall, the city receives a moderate amount of precipitation, which most often falls in the form of light or moderate rain, and in winter – snow.

The highest amount of precipitation, about 3 mm per month, usually falls in the summer months – June, July, and August. At the same time, July stands out as the wettest month, counting on average 16 days with precipitation. During this period, precipitation typically falls as rain. The driest months in terms of rainfall are considered to be March and April, when only about 1 mm falls. In the winter months, especially in January (with an average minimum of -0.8°C) and February (with an average minimum of -0.9°C), when temperatures often drop below zero, precipitation frequently falls as snow. For example, in January, about 15 days with precipitation are registered with a total volume of 2 mm, indicating frequent but not heavy snowfalls or drizzle.

In general, Gdansk is characterized by frequent, but not too intense cloudiness with precipitation throughout the year. Even in months with the fewest days of precipitation, such as April or September (10 days each), the probability of rain remains. Transitional seasons, spring and autumn, are characterized by mixed types of precipitation, where rains may alternate with cooler weather, and the first snow is already possible in November. Travellers should be prepared for changeable weather and have an umbrella or raincoat with them at practically any time of the year.

When planning a trip to Gdansk, it is important to consider the changeable weather of the Baltic coast. A key tip is to dress in layers. Even in summer, evenings can be cool, and in winter, the temperature often drops to around zero or below. An indispensable item in your suitcase will be comfortable waterproof shoes, as there are many cobblestones in the city, and precipitation in the form of rain or drizzle is possible all year round, judging by the number of "wet days" monthly (from 10 to 16). Also, do not forget an umbrella or a light waterproof jacket with a hood, which is especially relevant due to frequent, though not always heavy, precipitation (1-3 mm per month).

In the summer months (June-August), when the average temperature ranges from 17°C to 19°C, you will need light clothes, T-shirts, shorts, or skirts. However, be sure to bring a sweater or fleece jacket and a windbreaker, as the coastal wind can be noticeable, and evenings are cool. Sunscreen and sunglasses will also be useful on clear days. For spring (April-May) and autumn (September-November) trips, when the temperature varies from 5°C to 15°C, pack warm sweaters, jeans or thick trousers, a mid-season jacket (preferably windproof and water-resistant), and perhaps a light hat and gloves, especially for November and March.

In winter (December-March) it is cold in Gdansk, with average temperatures hovering around 0°C - 3°C, but they can drop lower. You will definitely need a warm winter jacket or coat, a hat, a scarf, gloves, and warm socks. Thermal underwear can be a great addition, especially if you plan long walks. Regardless of the season, a light backpack for day excursions, where you can put a raincoat, a bottle of water, or purchased souvenirs, will make your journey more comfortable.
