Packing for Munich in September means dressing for 18°C days and 10°C evenings. A mid-weight jacket over a sweater handles 18°C daytime temperatures; the combination stays comfortable all day without overheating. Evening temperatures settle at 10°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: Munich'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.

Why is Munich mild in September?
September brings the first meaningful shift toward cooler conditions in Munich, as the sun angle drops and day length shortens. Temperatures averaging 18°C by day and 10°C overnight are still comfortable by most standards, but the trend is clearly downward. At 48 degrees north latitude, autumn light has a particular quality: lower in the sky and warmer in tone, it gives the city a photogenic quality quite different from summer. Evening temperatures already demand a jacket, but midday hours stay pleasant for sightseeing. Climate data: Open-Meteo ERA5 (1991–2020).
