France Lyon Weather in August — Climate Guide
August in Lyon is moderate
August is moderate for Lyon.
August in Lyon is hot and noticeably quieter, as many locals leave on holiday. It averages 28°C/16°C — heatwaves can exceed 33°C — with low rainfall (65mm) and strong sun.
The big caveat is closures: a significant number of bouchons, family restaurants, and shops shut for several weeks of summer holidays, so the famous Lyonnaise food scene runs at reduced capacity. Check specific restaurants before counting on them. The flip side is a calmer, less crowded city and softer hotel prices than peak spring.

Lyon in August — Full Picture
August in Lyon is hot and noticeably quieter, as many locals leave on holiday. It averages 28°C/16°C — heatwaves can exceed 33°C — with low rainfall (65mm) and strong sun.
The big caveat is closures: a significant number of bouchons, family restaurants, and shops shut for several weeks of summer holidays, so the famous Lyonnaise food scene runs at reduced capacity. Check specific restaurants before counting on them. The flip side is a calmer, less crowded city and softer hotel prices than peak spring.
It's a good month to lean on day trips — Annecy's lake is glorious (if busy) and a welcome escape from the heat. Larger brasseries (like Brasserie Georges) and Les Halles tend to stay open when small bouchons close.
Note: peak heat and the stone old town call for morning-and-evening sightseeing, plenty of water, and shade. Confirm restaurant openings ahead, and consider the lake or shaded parks for the hottest hours.
What to Wear & What to Pack
Hot summer — around 28°C/16°C, with heatwaves possible past 33°C. Light, breathable clothing, a hat, sunglasses, and SPF 30-50. Carry water. A thin layer for the rare cool evening.
