Austria Innsbruck Weather in September — Climate Guide
September in Innsbruck is high
September is high for Innsbruck.
September is one of the finest months in Innsbruck — mild at around 19°C/8°C (66°F/46°F), with clearer, more settled air than the stormy heart of summer and the first touches of autumn color on the slopes.
This is prime hiking and cable-car weather: the afternoon thunderstorms ease, visibility from the peaks is often superb, and the crowds thin from the August peak while prices soften. The Nordkette, Stubai, and valley trails are all still open.

Innsbruck in September — Full Picture
September is one of the finest months in Innsbruck — mild at around 19°C/8°C (66°F/46°F), with clearer, more settled air than the stormy heart of summer and the first touches of autumn color on the slopes.
This is prime hiking and cable-car weather: the afternoon thunderstorms ease, visibility from the peaks is often superb, and the crowds thin from the August peak while prices soften. The Nordkette, Stubai, and valley trails are all still open.
Tyrol's traditional Almabtrieb (the decorated cattle drive down from the high summer pastures) takes place around now in nearby valleys — a colorful, authentic Alpine event worth catching if the dates line up.
Note: mornings and evenings turn crisp, and the high trails cool quickly, so pack a warm layer. Daylight shortens noticeably through the month. Overall, September offers the best balance of clear weather, open mountains, and easing crowds — a top choice for hikers.
What to Wear & What to Pack
Mild early autumn — around 19°C/8°C (66°F/46°F). Light layers with a jacket or sweater for cooler mornings and evenings; a light rain layer. Hiking gear and a warm layer for the mountains. Clearer, more stable air than midsummer.
