Climate overview
Temperature
The coldest monthly mean is in February, at -11.9 °C; the warmest is in August, at 13.4 °C. These are averages for each month, not typical daytime maximum temperatures, so they should not be read as the full range visitors will experience on individual days. The unweighted mean across monthly means is 0.8 °C, a broad summary rather than a day-weighted annual average.
Rain
Mean daily rainfall is lowest in February, at 0.20 mm/day, and highest in September, at 3.94 mm/day. The unweighted mean across monthly daily means is 1.92 mm/day. These figures describe average daily amounts, not monthly totals; they also do not show how often rain falls or guarantee dry weather in the lower-rainfall month.
Snow
Mean daily snowfall reaches its monthly high in March, at 24.91 mm/day; the unweighted mean across monthly daily averages is 11.96 mm/day. These amounts do not establish how many days have snowfall, how deep snow becomes, whether snow cover persists, or whether conditions suit skiing.
Sunshine
Mean daily sunshine is highest in July, at 9.38 hours/day, and lowest in December, at 3.46 hours/day. The unweighted mean across monthly averages is 6.44 hours/day per day. Sunshine duration can help frame outdoor plans, but it is not a measure of day length and does not promise the same amount of sun on each day.

For visitors prioritising lower average rainfall, February is the conditional option in this record, with mean daily rainfall of 0.20 mm/day. That average is not a promise of dry days or a measure of rain frequency, so keep plans flexible and bring suitable rain protection; mean daily rainfall is not a monthly total. Those prioritising cooler monthly means can consider February, when the monthly mean is -11.9 °C; this is not a daytime maximum, and daily conditions can differ from the average. For rain preparation, note that mean daily rainfall is highest in September, at 3.94 mm/day, which still cannot predict whether it will rain on a particular visit.
For outdoor sightseeing planned around average sunshine duration, July has the highest mean daily sunshine at 9.38 hours/day, while December has the lowest at 3.46 hours/day. These are useful planning reference points, not guarantees of sunshine or measures of daylight length; the sunshine figures do not by themselves establish a universally best time to visit. Snowfall averages also warrant practical caution: the highest mean daily amount is in March, at 24.91 mm/day. This does not tell visitors how many snowy days to expect or establish snow depth or cover, so it cannot alone determine conditions for driving or winter activities.
