Climate overview

Temperature

December has the lowest monthly mean temperature, -6.8 °C, while the highest monthly mean arrives in July at 17.1 °C. These are monthly averages rather than daytime maximum or minimum readings, so individual days can differ from the broad pattern. Across the calendar months, the unweighted mean of monthly means is 4.0 °C; it is not a day-weighted annual average.

Snow

Mean daily snowfall is highest in December at 17.04 mm/day; the unweighted mean across the monthly daily-snowfall means is 8.90 mm/day. These amounts are daily averages, not monthly totals. They do not establish how many days receive snow, snow depth or cover, or whether conditions suit skiing, so visitors should not treat the averages as a guarantee of ground conditions.

Rain

Mean daily rainfall is highest in July at 1.24 mm/day, and lowest in both January / December at 0.01 mm/day. The figures describe average daily amounts, not monthly totals, and lower average rainfall does not guarantee rain-free days or indicate how often rain occurs. The unweighted mean across monthly daily-rainfall means is 0.52 mm/day, providing context rather than a forecast for a particular visit.

Sunshine

Mean daily sunshine duration reaches its highest monthly value in June at 13.39 hours/day, and its lowest in December at 6.51 hours/day. These averages can help with broad outdoor-planning expectations, but sunshine duration is not the same as day length and does not promise clear conditions on any particular day. The unweighted mean of the monthly sunshine means is 10.05 hours/day.

For visitors prioritising cooler monthly averages, December is the relevant option, with a mean temperature of -6.8 °C; this is not a daytime low or a forecast for a specific trip. Those seeking the highest average sunshine duration for outdoor planning may instead look to June, which averages 13.39 hours/day per day. Sunshine hours indicate duration, not day length or guaranteed clear skies. If lower average rainfall is the priority, consider January / December, where the tied monthly mean is 0.01 mm/day per day. Rain preparation is especially relevant for July, the month with the highest mean daily rainfall at 1.24 mm/day. These averages do not quantify rain frequency or rule out wet days, so they support a criterion-based choice rather than identifying one universally best time to visit.
