Monthly mean temperatures range from -1.8 °C in February to 16.6 °C in August, giving a broad outline of the year's thermal range.

Climate overview
Temperature
The coolest monthly mean temperature is -1.8 °C in February, while the warmest is 16.6 °C in August. These are averages across each month, not daytime maximum temperatures, and they cannot show how much conditions may vary from day to day. Across the calendar months, the unweighted mean of monthly mean temperatures is 6.1 °C. It provides a broad summary, but is not a day-weighted annual average or a description of conditions on a particular date.
Rain
Mean daily rainfall reaches its highest monthly value, 4.68 mm/day, in November, and its lowest, 2.32 mm/day, in March. These daily averages distinguish the relative monthly levels, but do not tell visitors how often rain occurs or guarantee dry weather in the lower-rainfall month. The unweighted mean of the monthly mean daily rainfall values is 3.42 mm/day. This is an average daily amount across monthly averages, not a monthly rainfall total.
Snow
Mean daily snowfall reaches its highest monthly value, 17.65 mm/day, in February. The unweighted mean of the monthly mean daily snowfall values is 5.62 mm/day; these averages do not establish the number of snowy days, snow depth, snow cover or skiing conditions.
Sunshine
Mean daily sunshine is highest at 9.47 hours/day in August and lowest at 3.02 hours/day in December. The figures can help set expectations for average sunshine when planning outdoor time, but sunshine duration is not the same as day length. The unweighted mean of monthly mean daily sunshine duration is 6.52 hours/day. It summarizes the monthly averages rather than predicting the sunshine available on a specific day.

If lower average rainfall is a priority, March is the conditional option: its mean daily rainfall is 2.32 mm/day. This does not guarantee rain-free days or indicate how frequently rain occurs, so it is still sensible to prepare for variable weather. For cooler monthly mean temperatures, consider February, when the mean is -1.8 °C; this is not a forecast of daytime highs or conditions throughout the month. Visitors who want to prepare for the highest average daily rainfall should note November, at 4.68 mm/day, and pack weather-appropriate rain protection rather than assuming every day will be wet.
For outdoor plans guided by average sunshine, August has the highest mean daily duration at 9.47 hours/day, while December has the lowest at 3.02 hours/day. These figures can inform expectations for daylight outdoor planning, but sunshine duration is not day length and cannot predict conditions on a particular date. The highest mean daily snowfall occurs in February, at 17.65 mm/day. This average alone does not show how many days will have snow or whether snow will lie on the ground, so it cannot establish snow-cover or skiing conditions for a trip.
