September 2025 in Switzerland

In September, Switzerland offers a perfect blend of late summer warmth and early autumn beauty. The weather remains pleasant, making it ideal for outdoor activities like hiking through the changing colors of the Alps and enjoying lake views. The grape harvest season begins, and visitors can explore Swiss vineyards, taking part in wine tours and tastings, especially in regions like Lavaux. Cultural events like the Zurich Film Festival and the Alpabfahrt (cattle descent) celebrations in the Swiss Alps offer unique experiences. With fewer crowds than the summer months, it’s a great time to explore Swiss cities, relax in mountain resorts, and enjoy the crisp air of the upcoming fall season.
