Climate overview

Temperature

Monthly mean temperature is lowest at -4.7 °C in January, and highest at 13.4 °C in July. These are averages for each month, not daytime maximum temperatures, so they describe the broad monthly pattern rather than the range a visitor may experience within a day. The unweighted mean of the monthly means is 3.3 °C; it is not a day-weighted annual average.

Rain

Mean daily rainfall is lowest at 0.71 mm/day in March, making that month a conditional option for visitors prioritising lower average rainfall. The highest monthly mean is 4.76 mm/day in August, a useful cue to include rain-ready clothing when planning then. These are daily averages, not monthly totals, and they do not show how often rain falls or guarantee dry days. The unweighted mean across monthly means is 2.44 mm/day.

Snow

Mean daily snowfall reaches its highest monthly level at 29.70 mm/day in March. The unweighted mean across monthly means is 12.27 mm/day. These are snowfall amounts expressed as daily means, not monthly totals; they do not establish the number of snowy days, snow depth, snow cover or skiing conditions.

Sunshine

Mean daily sunshine reaches its highest level at 12.05 hours/day in July, while the lowest monthly mean is 0.00 hours/day in December. The sunshine figures can help with outdoor planning, but hours of sunshine are not the same as day length and do not guarantee clear weather throughout a day. Across the calendar-month means, the unweighted mean is 5.92 hours/day hours per day.

For daylight outdoor planning, July has the highest mean daily sunshine duration at 12.05 hours/day, while December has the lowest at 0.00 hours/day.
