Zurich in September

When to go

MeteoSwiss lists September normals for its Zürich Fluntern station, so compare them with June and July when you choose a month and check a forecast before you go. Zürich Tourism dates Knabenschiessen, which it describes as a public festival open to all visitors, and the Zurich Film Festival, which runs from late in the month into October. It also lists Knabenschiessen among the city's additional public holidays and says stores are generally closed on public holidays, so check opening hours around the festival.
