France Lyon Weather in September — Climate Guide
September in Lyon is very-high
September is very-high for Lyon.
September in Lyon is one of the best months — warm days, cooler nights, and the city back to life after the August lull. It averages 24°C/13°C with moderate rainfall (80mm).
The Beaujolais grape harvest (vendanges) makes a wine-country day trip especially rewarding now, with the vineyards busy and the new vintage in the making. Bouchons reopen after summer holidays, terraces stay lively, and the weather is comfortable for walking the traboules, Fourvière, and Croix-Rousse.

Lyon in September — Full Picture
September in Lyon is one of the best months — warm days, cooler nights, and the city back to life after the August lull. It averages 24°C/13°C with moderate rainfall (80mm).
The Beaujolais grape harvest (vendanges) makes a wine-country day trip especially rewarding now, with the vineyards busy and the new vintage in the making. Bouchons reopen after summer holidays, terraces stay lively, and the weather is comfortable for walking the traboules, Fourvière, and Croix-Rousse.
In alternating years, the Biennale de la Danse or the Biennale d'Art Contemporain brings major cultural programming. Day trips to Annecy and Pérouges are still excellent before autumn deepens.
Note: early autumn can bring showers, so carry an umbrella, and evenings cool down — keep a light layer for late dinners. September pairs great weather with the full return of Lyon's food scene, making it a top shoulder month.
What to Wear & What to Pack
Warm, mild early autumn — around 24°C/13°C. Short or long sleeves with a light layer for cooler evenings. A folding umbrella for showers. Sunglasses for sunny days.
