Climate overview

Temperature

Monthly mean temperature is lowest in January, at 4.2 °C, and highest in July, at 28.5 °C. These are averages for each month, not daytime highs, so they do not show the full range visitors may encounter from day to day. The unweighted mean across the calendar-month means is 16.5 °C. It provides a broad annual reference, but is not a day-weighted average and should not be read as the expected temperature for every month.

Rain

Mean daily rainfall reaches its highest monthly average in May, at 4.65 mm/day. Visitors planning outdoor activities around that period may want to allow for rain and bring suitable protection; this average does not say how frequently rain occurs or guarantee wet weather on a particular day. The lowest mean daily rainfall is in January, at 0.94 mm/day, which may suit visitors prioritising a lower average amount of rain. The figure is a daily mean, not a monthly total, and does not guarantee dry days. The unweighted mean of the monthly daily-rainfall averages is 2.36 mm/day.

Snow

Mean daily snowfall is highest in February, at 2.80 mm/day. This small daily-average figure records snowfall, but cannot establish how many snowy days occur, snow depth, snow cover, or whether conditions are suitable for skiing. The unweighted mean across the monthly daily-snowfall averages is 0.47 mm/day.

Sunshine

Mean daily sunshine is highest in July, at 12.02 hours/day, and lowest in December, at 6.78 hours/day. These averages can help with planning daylight outdoor time, but sunshine duration is not the same as day length and does not promise clear conditions on a given day. Across the calendar months, the unweighted mean of daily sunshine averages is 9.28 hours/day. It is a broad reference rather than a day-weighted annual average.

If lower average rainfall is your priority, January is the conditional option in the supplied figures, with mean daily rainfall of 0.94 mm/day; it is not a guarantee of dry weather. For cooler monthly mean temperatures, consider January, where the average is 4.2 °C. These criteria point to different aspects of travel weather, not a single universally best time to visit. For outdoor sightseeing, mean daily sunshine is highest in July, at 12.02 hours/day, and lowest in December, at 6.78 hours/day. These figures can inform planning but do not represent day length or ensure sunshine on your visit.

Rain preparation may be especially relevant in May, when mean daily rainfall reaches 4.65 mm/day; the average does not describe rain frequency or predict conditions on a particular date. The recorded snowfall average peaks in February at 2.80 mm/day, but it cannot tell visitors how many snowy days to expect or whether snow will lie on the ground.
