Good to Know
- Winter (November–April) demands full thermal gear: insulated jackets, multiple clothing layers, hats, gloves, scarves. Summer (June–August) is cool (~9–11.5°C (48–53°F)); bring layered clothing and a light jacket even on warm days.
- Precipitation is frequent but often light—expect 12–22 days with rain or snow per month. A waterproof jacket and water-resistant shoes are essential year-round.
- High-altitude alpine weather is highly changeable within a single day. Always check forecasts and be prepared for sudden shifts regardless of season.
- Summer months (June–August) offer the most reliably pleasant weather for hiking and outdoor activities, though June still sees frequent rain.
- Spring and autumn are highly unpredictable; pack for both sunny and rainy, even snowy conditions using the layering principle.
