Climate overview
Temperature
Monthly mean temperatures range from a low of 14.3 °C in January to a high of 21.6 °C in May; these are monthly averages, not daytime maximum temperatures. Across the calendar-month means, the unweighted mean is 18.2 °C. These figures offer a broad guide to the temperature pattern, but do not describe daily highs and lows or guarantee how a particular day will feel.
Rain
Mean daily rainfall reaches its highest monthly average in June, at 3.78 mm/day, while its lowest monthly average is in February, at 0.15 mm/day. The unweighted mean across the calendar-month means is 1.62 mm/day. These are daily amounts rather than monthly totals, and the lower average does not mean that every day in that month will be dry or indicate how often rain falls.
Sunshine
Mean daily sunshine is highest in May, at 11.71 hours/day, and lowest in December, at 9.38 hours/day. The unweighted mean across calendar-month means is 10.50 hours/day hours per day. Sunshine duration can help with broad outdoor planning, but it measures average sunshine time, not day length or a promise of clear skies on any given day.
Snow
The highest monthly mean daily snowfall is 0.06 mm/day in March, and the unweighted mean across calendar-month means is 0.01 mm/day. These small recorded averages do not show how many days receive snow, its depth or whether snow cover develops, so they cannot establish snow or skiing conditions.

If lower average rainfall is a priority, February is the conditional option in these figures, with mean daily rainfall of 0.15 mm/day. This is not a guarantee of dry days, nor does it quantify rain frequency; carry suitable rain protection if plans depend on being outdoors. For visitors prioritising cooler monthly averages, January has the lowest monthly mean temperature, 14.3 °C. It is a useful broad comparison for travel planning, but it is not a forecast of daytime highs or conditions on an individual visit.
Rain preparation is especially relevant when considering June, the month with the highest mean daily rainfall at 3.78 mm/day; an average cannot predict whether rain will coincide with a specific outing. For daylight outdoor planning, mean daily sunshine is highest in May at 11.71 hours/day, and lowest in December at 9.38 hours/day. These sunshine durations are averages, not day length or a guarantee of sunshine.
