Climate overview
Temperature
January has the lowest monthly mean temperature, 11.1 °C, while August has the highest, 24.8 °C. These figures describe monthly averages, not daytime maximum temperatures, so they do not show the full range visitors may encounter within a day. The unweighted mean across the monthly means is 17.6 °C; it is a summary of the months, not a day-weighted annual average.
Sunshine
Mean daily sunshine duration reaches its highest monthly value in June, at 13.19 hours/day, and its lowest in December, at 7.21 hours/day. This can help with planning daylight outdoor time, but sunshine duration is not the same as day length and does not guarantee uninterrupted sun. The unweighted mean across monthly sunshine means is 10.35 hours/day.
Rain
Mean daily rainfall is lowest in July, at 0.02 mm/day, and highest in January, at 2.55 mm/day. The figures are daily means, not monthly totals, and a low average does not guarantee rain-free days or indicate how often rain falls. Across the calendar months, the unweighted mean of monthly daily-rainfall means is 0.96 mm/day.
Snow
The highest monthly mean daily snowfall is recorded in January, at 0.13 mm/day; the unweighted mean across monthly snowfall means is 0.02 mm/day. These are average daily amounts, not monthly totals, and do not establish how many days have snowfall, its depth, or whether snow cover develops.

If lower average rainfall is your priority, July is the conditional option in these data, with mean daily rainfall of 0.02 mm/day. It does not guarantee dry days, so this average alone cannot determine whether rain will affect a particular outing.
