Packing Recommendations
Layers Are Key
Temperatures can swing 10°C between sunny afternoons and cool evenings. Bring a warm sweater or light jacket you can tie around your waist.
Rain Gear
A compact umbrella or light rain jacket is essential - there is a 30-45% chance of rain on any given day. Waterproof shoes recommended.
Sun Protection
September sun can still be strong, especially in beer gardens. Sunglasses and SPF 30+ sunscreen are wise, particularly for the first week.
Evening Warmth
After sunset, temperatures drop quickly. A scarf or hat for late nights makes the walk back much more comfortable.
