Prepare for warm summer days and cool, sometimes frosty, winters.

Summer in Strasbourg is usually pleasantly warm, with average temperatures in July and August reaching 20-21°C, while maximum values can rise to 25-26°C. This is the ideal time for walking around the city and enjoying its beauties. Winters, on the contrary, are quite cool: the average temperature in January and December holds around 3-4°C, often dropping below freezing, especially at night. Spring and autumn are transitional seasons with milder but changeable weather.

As for precipitation, it is distributed quite evenly throughout the year in Strasbourg, without a clearly defined rainy season. Monthly precipitation is low, usually amounting to 2-3 mm. However, the number of days with precipitation ranges from 11 to 18 per month, which indicates the possibility of frequent but usually light rains or overcast weather. Therefore, regardless of the season, a light umbrella or raincoat can prove to be a useful companion on your journey through Strasbourg.

In Strasbourg, a noticeable change in temperature regimes is observed throughout the year, which is characteristic of its temperate continental climate. The hottest months are traditionally July and August. During this period, the average daily temperature confidently holds around 20.8-20.9°C, and maximum values on the warmest days can reach 25-26°C. Conversely, the coldest period falls in January, when the average temperature is about 3.4°C, and night minimums average down to 0.9°C.

The summer months in Strasbourg, from June to August, gift residents and guests of the city with pleasant warmth. Daytime highs during this period often range from 24°C to 26°C, creating comfortable conditions for long walks and sightseeing. An important feature of summer weather is noticeable diurnal temperature fluctuations: the difference between daytime highs and night lows can reach about 10°C (for example, in July the average maximum is +25.9°C, and the minimum is +15.8°C). This means that even after a hot day, evenings can be quite fresh, and a light cardigan or jacket won't go amiss.

Winter in Strasbourg, covering December, January, and February, is characterised as cool. Average temperatures in December and January hold at the level of 3-4°C. At night, the thermometer regularly drops to values around 1-2°C, and in January the average minimum reaches 0.9°C, which often leads to frosts. Daytime temperatures in the coldest months usually do not rise above 6-9°C. February brings some softening, with an average temperature of 5.3°C and an average maximum of almost 9°C. Winter diurnal temperature fluctuations are less pronounced than in summer and amount to approximately 4-7°C.

In Strasbourg, precipitation is characterised by a fairly even distribution throughout the year, without a clearly defined season of torrential rains or prolonged drought. Total monthly precipitation is low and fluctuates within 2-3 mm. This suggests that intense and prolonged downpours are not typical for the city; rather, one should expect frequent but usually light precipitation.

Despite the small total amount, precipitation in Strasbourg falls quite frequently. The highest number of days with precipitation is observed in the winter period: December is the record holder with an average of 18 days with precipitation, followed by January (16 days) and November (15 days). The "driest" months in terms of precipitation frequency are considered April and September, when there are on average 11 days with precipitation. In the remaining months of the year, the number of days with precipitation varies from 12 to 14, highlighting the need to be prepared for changeable weather.

The nature of precipitation in Strasbourg changes depending on the time of year. In winter, especially in December and January, when average minimum temperatures drop to 0.9°C - 1.9°C, precipitation often falls as snow or sleet. In spring and autumn, it is usually light rain or drizzle. In summer, despite the warm weather, precipitation is also possible, but it is usually short-lived and not very intense, which corresponds to low average monthly figures.

When planning a trip to Strasbourg, it is worth remembering its temperate continental climate with distinct seasons and fairly frequent, though usually light, precipitation year-round. Therefore, comfortable shoes for long walks on cobbled streets are an absolute necessity at any time of year. Also, do not forget an umbrella or a light raincoat, as the number of days with precipitation is significant even in the summer months. The principle of layering in clothing will become your best friend, allowing you to easily adapt to temperature changes throughout the day, especially in transitional seasons.

If your trip falls in summer (June-August), when average temperatures rise to 20-21°C and maximums to 25-26°C, pack light clothing: T-shirts, shorts, and dresses made of natural fabrics. Don't forget sunscreen and a hat. However, even in summer, evenings can be cool, so a light jacket or sweater will come in handy. In winter (December-February), it is cold in Strasbourg, average temperatures drop to 3-5°C, and night temperatures can be below freezing. You will need a warm jacket, hat, scarf, gloves and warm waterproof shoes, as precipitation may fall as snow. In spring (March-May) and autumn (September-November), the weather is changeable: pack sweaters, a mid-season jacket (preferably waterproof) and be ready for both sunny and rainy days.

Regardless of the season, consider that even with a small total amount of millimetres of precipitation, there are quite a few rainy days in Strasbourg (from 11 to 18 per month). Therefore, clothing capable of protecting against wind and light rain will be very useful. Adapt your wardrobe to the specific forecast before the trip, but always have something with you in case of a sudden change in weather to fully enjoy the beauties of Strasbourg.
