Climate overview
Temperature
The monthly mean temperature is warmest in July, at 16.0 °C, and coolest in December, at -11.2 °C. These are monthly averages, not daytime highs or lows, and do not describe the range a visitor might experience within a day. Across the calendar-month means, the unweighted mean is 1.9 °C. It provides a broad summary of the period, but is not a day-weighted annual average and should not be read as a typical temperature for every month.
Snow
Mean daily snowfall has its monthly high in April, at 8.37 mm/day, and its low in July, at 0.12 mm/day. These are average daily amounts, not monthly totals; they do not establish the number of snowy days, snow depth or snow cover. The unweighted mean across calendar-month snowfall averages is 5.09 mm/day. This summary alone cannot indicate snow conditions on a particular date or establish skiing conditions.
Rain
Mean daily rainfall reaches its monthly high in June, at 3.05 mm/day. This daily mean is not a monthly total, and it does not show how often rain falls or whether a particular day will be wet. The monthly low is 0.01 mm/day in January; the unweighted mean across calendar-month means is 0.90 mm/day. These averages offer a comparison of typical daily amounts, but neither guarantees dry weather nor measures rain frequency.
Sunshine
Mean daily sunshine duration is highest in July, at 13.02 hours/day, and lowest in December, at 4.73 hours/day. These figures describe average sunshine duration, not day length, and do not guarantee how much sun any individual day will bring. The unweighted mean across calendar-month sunshine averages is 8.94 hours/day. It is a broad period summary rather than a day-weighted annual figure.

For visitors prioritising lower average rainfall, January is the conditional option, with mean daily rainfall of 0.01 mm/day; pack for changeable weather regardless, since this average does not promise rain-free days or describe rain frequency. Rain preparation is especially relevant in June, when the mean daily amount is 3.05 mm/day. Those who prefer cooler monthly averages can consider December, whose monthly mean is -11.2 °C. It is not a daytime minimum, so use it as a broad clothing-planning reference rather than a forecast for a specific visit.
For daylight outdoor planning, mean daily sunshine duration is highest in July at 13.02 hours/day, and lowest in December at 4.73 hours/day. Sunshine duration is not day length, and these averages cannot guarantee conditions on an individual sightseeing day. Snowfall’s monthly mean daily high occurs in April, at 8.37 mm/day. This amount alone cannot tell visitors how many days will have snow, how deep it may be, or whether snow cover will be present, so it is not a measure of skiing conditions.
