The climate in Gdynia, located on the Baltic Sea coast in Poland, can be described as temperate marine. This means the city is influenced by the sea, which moderates temperature extremes. Gdynia has four distinct seasons: a cool, sometimes frosty winter, a gradually warming spring, a moderately warm summer, and a cool autumn. Overall, the weather here is quite variable but without sharp fluctuations.

Winter months (December–February) in Gdynia are characterized by average temperatures of around 1.5–2.3°C, with minimum values dropping to zero or slightly below. Summer (June–August) brings more comfortable weather with average temperatures ranging from 16.8°C to 18.8°C, while maximum daytime temperatures can reach 20–22°C. Spring and autumn are transitional seasons with gradual temperature changes.

A feature of Gdynia's climate is the relatively even distribution of precipitation throughout the year, although the total amount is low – averaging 1–3 mm per month. However, the number of days with precipitation is quite significant, ranging from 9 to 16 days per month. This indicates that Gdynia often experiences overcast days with light, drizzling rain or snow (in winter), while heavy downpours or prolonged rains are relatively rare.

The climate in Gdynia is characterized by moderate temperatures throughout the year, with clearly defined seasons. The coldest months are January and February, when the average temperature is around 1.5°C and 1.8°C respectively. In these months, minimum temperatures can drop to -0.1°C, and maximums rarely exceed 3.0°C - 3.7°C. The warmest months are July and, especially, August. In August, the average temperature reaches 18.8°C, with daytime highs averaging around 21.9°C and nighttime lows around 15.8°C.

The summer period in Gdynia, covering June, July, and August, offers pleasant warmth. Average maximum temperatures range from 20.1°C in June to 21.9°C in August. Nights also remain comfortably warm, with minimum temperatures from 13.4°C in June to 15.8°C in August. This time is ideal for walking and relaxing by the coast, although it is worth noting that July can be quite rainy. The difference between daytime and nighttime temperatures in summer is approximately 5-7 degrees, ensuring comfortable evenings after warm days.

Winter in Gdynia, spanning December, January, and February, is quite cool, but severe frosts are rare. Average monthly temperatures during this period are as follows: about 2.3°C in December, falling to 1.5°C in January, and rising slightly to 1.8°C in February. Daytime highs in the winter months usually stay just above zero, varying from 3.0°C in January to 3.8°C in December, while nighttime lows can drop to -0.1°C, especially in January and February. Transitional seasons, spring and autumn, show a gradual change in temperatures. For example, in April the average temperature is 6.8°C, and in October it is 10.9°C. Fluctuations between daytime and nighttime temperatures during these periods are also moderate, which is typical for a coastal climate.

In Gdynia, precipitation is characterized by a small total volume throughout the year, and the city does not experience pronounced wet or dry seasons in terms of total millimeters. Nevertheless, the frequency of days with precipitation is quite high for most of the year. The highest amount of precipitation, totaling 3 mm, falls in July, which is also one of the months with the maximum number of wet days (16). The "driest" months by precipitation volume are March and April, when only 1 mm falls.

The winter months, from December to February, as well as the beginning of spring in March, bring the coldest weather: average minimum temperatures in January and February can drop to -0.1°C. During this period, precipitation, which amounts to 1–2 mm per month, most often falls as snow or sleet. Despite the small monthly amount, the number of days with such precipitation remains significant: 16 days in January, 15 days each in February and December, and 12 days in March. This indicates frequent but generally light snowfall or drizzle.

With the arrival of warmer weather, the nature of precipitation changes to rain. April sees the fewest days with precipitation in the year — only 9 days — and it remains one of the driest by volume (1 mm). In summer, especially in July, the frequency of rain increases again to 16 days, and the monthly precipitation volume reaches its peak at 3 mm, suggesting frequent but moderate rain. In the other months of the warm period (May–June, August–November), the amount of precipitation is about 2 mm, and the number of rainy days ranges from 11 to 15, indicating regular but usually not too intense precipitation, which turns into colder weather with the possibility of the first snow by late autumn.

When planning a trip to Gdynia, it is important to consider the changeable weather of the Baltic coast. Layering should be the key principle when packing your suitcase. Regardless of the time of year, you will need comfortable shoes for walking around the city and the promenade, as well as an umbrella or a light waterproof jacket, as precipitation, though not always heavy, occurs quite frequently throughout the year. Even in the summer months, the evening sea breeze can be cool, so a light sweater or windbreaker will be useful.

In summer (June–August), when the average temperature ranges from 16°C to 19°C, your main wardrobe can consist of T-shirts, shorts, light trousers, and dresses. However, don't forget to pack jeans or heavier trousers and a sweater for cool evenings or days with variable weather. Sunscreen and a hat will also come in handy for sunny days. In July and August, despite the comfortable temperatures, the number of days with precipitation remains significant, so a raincoat or umbrella is essential.

In the cold season, from November to March, when the average temperature stays around 0–6°C, you will need warm winter clothing: a down jacket or insulated coat, a hat, scarf, and gloves. Waterproof shoes with non-slip soles will be very useful, given the frequent precipitation and possible icy conditions. During the transitional seasons – spring (April–May) and autumn (September–October) – the weather can be unpredictable. During the day, temperatures can rise to 10–18°C, but mornings and evenings are significantly cooler. Therefore, the ideal choice is clothing that is easy to combine: T-shirts, long-sleeved tops, sweaters, a mid-season jacket, and, of course, something for the rain.
