Strasbourg weather in May

May is one of the loveliest months to visit Strasbourg, with mild spring weather and plenty of daylight. Daytime temperatures average 20°C (68°F), while nights cool to around 10°C (50°F). You can expect roughly 83mm of rainfall spread across about 12 rainy days, so showers are fairly common but typically brief. With over 11 hours of sunshine daily, you'll have excellent conditions for exploring the old town and riverside walks.

May in Strasbourg coincides with the tail end of spring festivals and the beginning of outdoor café season. The city's famous flower displays are in full bloom, and the Ill River is particularly picturesque. Crowds are moderate—busy enough to feel vibrant, but before the peak summer tourist rush. The atmosphere is relaxed and perfect for wandering the charming canals and half-timbered streets.

For 2026, May is an ideal choice if you want pleasant weather without extreme heat or winter cold. Pack layers since mornings and evenings can be cool, and bring rain protection. Hotels and restaurants are reasonably busy but not overwhelmed, making it easier to book reservations and experience authentic local life.
