Climate overview
Temperature
The coolest monthly mean is January at 4.8 °C, while the warmest is August at 27.1 °C. These are monthly averages, not daytime maximum temperatures, so they describe the overall character of each month rather than the range a visitor might experience from day to day. Across the calendar-month means, the unweighted mean is 15.8 °C; it is not a day-weighted annual average.
Rain
Mean daily rainfall reaches its highest monthly level in October at 7.01 mm/day. For outdoor plans then, packing rain protection is sensible, but this average does not indicate how often rain falls or guarantee wet conditions on a particular day. The lowest monthly mean daily rainfall is in January at 1.68 mm/day, which describes a lower average amount rather than a promise of dry weather. The unweighted mean across monthly rainfall means is 4.22 mm/day; these figures are daily means, not monthly totals.
Sunshine
Mean daily sunshine is highest in August at 9.79 hours/day, and lowest in October at 6.76 hours/day. These averages may help with planning daylight outdoor activities, but sunshine duration is not the same as day length. The unweighted mean across calendar-month sunshine means is 8.01 hours/day per day, a broad reference rather than a forecast for any individual visit.
Snow
Recorded mean daily snowfall is highest in February at 3.40 mm/day. This small daily-average measure does not establish how many days have snow, how deep it becomes, whether snow cover persists, or whether conditions suit skiing. The unweighted mean across calendar-month snowfall means is 0.49 mm/day per day; it should not be read as a monthly total or a measure of snow depth.
