Packing for Geneva in August means dressing for 24°C days and 16°C evenings. A light cotton tee with a casual overshirt works well at 24°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 16°C, a modest 8°C drop that a light cardigan or denim jacket covers. European cobblestones reward low-profile walking shoes over flip-flops or heels, with cushioned trainers or leather walking shoes being the practical choice. A compact foldable umbrella weighs almost nothing and earns its keep across 12 potential rainy days.

💡

Local tip: Geneva's cobbled streets turn slippery in the rain. Waterproof walking shoes with a non-slip sole outperform fashionable footwear on wet stone, and you'll cover significantly more ground in comfort.
