Good to Know
- January and February offer excellent snow conditions but are extremely busy and expensive; March is an ideal compromise with reliable snow, longer daylight, and fewer crowds.
- At elevations above 1500m, almost all winter precipitation falls as snow and persists from November through May or June.
- Summer (July-August) features daytime highs around 15-17°C (59-63°F) and is ideal for hiking and mountain biking; expect occasional showers mixed with sunny days.
- Fog can form in winter valley inversions and persist for weeks in high-pressure conditions; this is a local winter phenomenon to be aware of.
- UV risk is extremely high even on cloudy days due to altitude (2.5km+) and snow reflection; Factor 60+ sun protection essential in winter and spring.
- Wind can be significant at altitude; the föhn wind can warm temperatures 15-20°C (59–68°F) in an hour, bringing low-humidity conditions.
