Snow and season in Thyon 2000
Above 2000 m snow can fall in any season and lies for months; watch the rain-snow limit and avalanche risk in winter.
To judge conditions, compare the snow line (≈ 300 m below the freezing level) with the village (2000 m) and the slopes (2460 m); above 50–60 km/h of summit wind, exposed lifts may close; a warm front lifts the freezing level within hours, a cold front brings snow down to the valley.
