Weather in Visby

To ensure your trip goes perfectly, check the weather forecast for Visby in advance. Below you will find up-to-date meteorological data and charts to help you plan your walks wisely.

The climate of Visby can be described as temperate maritime, significantly softened by the influence of the Baltic Sea. Thanks to its island location, extreme temperature fluctuations rarely occur here. Winter in the city is generally mild with temperatures just above zero, distinguishing it from the harsher conditions of mainland Sweden. Summer here is comfortable and fresh, without exhausting heat, making walks around the city particularly pleasant.

The most favourable time to visit is considered to be the period from June to August, when the average air temperature is around +16...+18°C, and daytime highs often reach +20°C. Spring arrives gradually, with April and May being among the "driest" months of the year with the fewest rainy days. Autumn sets in smoothly, maintaining a pleasant coolness in September before temperatures begin to drop noticeably.

It is worth noting that the weather in Visby can be changeable. The number of days with precipitation increases towards the end of the year: November and December are the wettest months, when rain or sleet can occur quite frequently (up to 15 days per month). Travellers planning a trip during the off-season or winter are recommended to bring waterproof clothing to feel comfortable in any weather.

The climate in Visby is largely determined by the influence of the Baltic Sea, which acts as a huge heat accumulator, smoothing out sharp temperature changes. Thanks to this, winter here is surprisingly mild for Swedish latitudes. The coldest months are January and February, yet even at this time, the average temperature stays in the positive range, around 1.5°C. Night frosts do occur, but they are usually insignificant: the average minimum rarely drops below -0.5°C, which allows for comfortable sightseeing provided you have warm clothing.

Summer in Visby can be characterized as moderately warm and very pleasant for travel. The peak warmth falls on July and August, when the air warms up during the day to an average of 20–21°C. Exhausting heat is a rarity here; comfortable weather prevails, ideally suited for long walks and excursions. An interesting feature is that August is often slightly warmer than July or stays at the same level, as the sea warms up to its maximum by the end of summer.

Transitional seasons in the city proceed smoothly, with the inertia characteristic of a maritime climate. Spring arrives leisurely: in March and April, the air warms up slowly. However, autumn, on the contrary, delights with warmth for a long time — September, with an average temperature of about 14.6°C, often feels like an "Indian summer". It is worth noting that Visby sees a very small difference between day and night temperatures throughout the year (usually just 3–5 degrees), creating a sense of stability and predictability in the weather.

Precipitation in Visby is distributed throughout the year in a rather peculiar way: although the total volume of moisture is low, the frequency of rainy or snowy days varies noticeably depending on the season. Winter here is generally the wettest period in terms of the number of inclement days. In December and January, precipitation falls most frequently — up to 13–15 days a month. Given the average temperatures hovering around zero and slightly above, the city is often covered in snow or wet snow during this time, lending the medieval streets a special charm.

The middle of spring can confidently be called the driest time of the year. April is characterized by minimal precipitation: on average, only about 6 rainy days are recorded here for the entire month. May and June also remain relatively dry (7–8 days with precipitation), making late spring and early summer a wonderful time for long walks and exploring the sights of Gotland island without fear of getting wet.

In the second half of summer and autumn, the frequency of precipitation increases again. In July and August, it may rain for about 11 days a month, but thanks to warm temperatures (averaging up to +18°C), showers are often short-lived. By October, the weather becomes more overcast and rainy (up to 14 days with precipitation), smoothly transitioning into the winter mode with the humidity characteristic of the Baltic.

The climate in Visby is largely determined by the Baltic Sea, so the weather here can be changeable and quite windy. The main principle when packing your suitcase is layering. Even in summer, a fresh breeze often blows from the sea, so be sure to take a high-quality windbreaker or a light jacket. In the cold season (from November to March), when the temperature stays just above zero and humidity rises, you will need windproof outerwear, a warm scarf, a hat, and gloves to feel comfortable during long walks by the water.

Summer in Visby is usually mild and pleasant, without exhausting heat: the average temperature in July and August is around +18°C. T-shirts, jeans, and light trousers are suitable for a trip in this season, but do not forget to pack a warm sweater or fleece jacket for cool evenings. Since light rains are possible throughout the year (statistics show from 6 to 15 rainy days per month), a compact umbrella or raincoat will become indispensable items in your backpack.

Particular attention should be paid to footwear. The historic city centre is famous for its medieval cobblestone streets, so comfortable trainers or boots with flat, stable soles are best suited for excursions; it is better to avoid high heels. If you are planning a trip during the sunny spring or summer months, be sure to bring sunglasses and sunscreen, as the sun on Gotland island can be quite active.
