Climate overview

Temperature

The coolest monthly mean is -3.2 °C in January, while the warmest is 18.9 °C in August. These are monthly averages, not daytime highs, and do not describe the range visitors may encounter from day to day. Across the calendar months, the unweighted mean of the monthly means is 8.2 °C; it is not a day-weighted annual average.

Rain

Mean daily rainfall is lowest in February, at 0.61 mm/day, and highest in July, at 3.09 mm/day. The figures describe average daily amounts for those months, not monthly totals or the likelihood of rain on a particular day. The unweighted mean across monthly means is 1.70 mm/day, which provides a broad reference rather than a forecast for any visit.

Sunshine

Average daily sunshine reaches its highest monthly mean in June, at 12.47 hours/day, and its lowest in December, at 1.43 hours/day. These figures can help with broad outdoor-planning expectations, but sunshine duration is not the same as day length and does not guarantee clear conditions on a given day. The unweighted mean of the monthly sunshine means is 6.92 hours/day.

Snow

The highest monthly mean daily snowfall is 8.06 mm/day in January; the unweighted mean across the monthly means is 2.41 mm/day. These are average snowfall amounts, not measures of how many days snow falls, snow depth or snow cover, so they cannot establish conditions for snow-dependent activities.

For visitors prioritising lower average rainfall, February is the conditional option in the supplied figures, with mean daily rainfall of 0.61 mm/day. This does not guarantee dry days or show how frequently rain occurs, so it is still sensible to prepare for changing weather. By contrast, July has the highest monthly mean daily rainfall at 3.09 mm/day, making rain preparation particularly relevant when planning travel then. Those who prefer cooler monthly averages may consider January, when the monthly mean temperature is -3.2 °C; it is not a prediction of daytime temperatures on travel dates. For daylight outdoor planning, mean daily sunshine is greatest in June at 12.47 hours/day and lowest in December at 1.43 hours/day. Sunshine duration does not indicate day length or promise clear skies, so these separate criteria should guide expectations rather than be treated as one universal best time to visit.
