Salzburg Weather in September

September weather in Salzburg

September feels mild rather than summery, with daytime highs around 20°C and cooler evenings near 10°C. Rain falls on 13 days, so showers can interrupt walks through Mirabell Gardens or along the Salzach. You'll still get plenty of good sightseeing weather, but don't count on a full day outdoors.

The damp can make longer hikes in the surrounding hills less appealing. Keep the Hohensalzburg Fortress and its Old Town lanes as rainy-day options; the fortress funicular saves you a steep climb.

Festivals and crowds

Rupertikirtag takes over the Old Town around St Rupert's Day in late September. Expect rides, food stalls and traditional dress around Domplatz and Residenzplatz. It's a fun time to visit, but those squares get crowded during the festivities.

Families who enjoy fairground rides and local traditions may especially like this week. Outside the festival, crowds tend to ease after August's busy summer season, and prices are generally less pressured than in peak summer. September is still a popular month, though, so don't expect the quietest streets of the year.

Making the most of your days

With autumn daylight and some cloudy, rainy spells, mix outdoor stops with indoor sights. Visit the gardens or stroll Getreidegasse when it's dry, then head to Mozart's Birthplace or the DomQuartier if rain sets in. September is one of Salzburg's best months overall, and October is cooler and wetter still.

For Rupertikirtag, check the festival layout before setting off: stalls and rides can make the usual route between the cathedral and Residenzplatz slow. If you're staying near the station, walk into the Old Town rather than relying on a bus through festival crowds.
