Climate overview
Temperature
The coolest monthly mean is January at 10.0 °C, while the warmest is July at 20.7 °C. These figures describe average temperatures for each month, not daytime maximums, and they cannot show the range visitors may encounter from one day to another. Across the calendar-month means, the unweighted mean is 15.5 °C; it is a summary of those monthly averages rather than a day-weighted annual average.
Rain
Mean daily rainfall reaches its supplied monthly high in October at 4.93 mm/day, and its low in July at 0.27 mm/day. The unweighted mean across the monthly daily means is 3.01 mm/day. These are average daily amounts, not monthly totals; they do not indicate how often rain falls or guarantee dry weather in the lower-rainfall month.
Sunshine
Average daily sunshine is highest in July at 12.86 hours/day, and lowest in December at 6.30 hours/day. The unweighted mean of the monthly sunshine averages is 9.52 hours/day per day. These duration averages can help with broad outdoor-planning expectations, but they are not a measure of daylight length and do not promise the same sunshine on each day.
