Climate overview
Temperature
Monthly mean temperatures are highest in February at 26.6 °C, while the lowest monthly mean is in August at 22.1 °C. These figures describe monthly averages, not daytime highs, so they do not show the range visitors might experience from day to day. Across the calendar-month means, the unweighted mean temperature is 24.4 °C; it is a summary of those monthly averages rather than a day-weighted annual figure.
Rain
Mean daily rainfall is highest in February at 10.74 mm/day, and lowest in September at 2.43 mm/day. These are daily mean amounts for the respective months, not monthly rainfall totals, and the lower average does not mean every day is dry. The unweighted mean of the monthly daily-rainfall means is 4.79 mm/day; this summary does not indicate how often rain occurs or how it is distributed among individual days.
Sunshine
Mean daily sunshine duration reaches its highest monthly average in December at 11.07 hours/day, compared with the lowest in June at 8.54 hours/day. Sunshine duration describes average hours of sunshine, not day length or a guarantee of clear weather. The unweighted mean across the monthly sunshine averages is 9.52 hours/day per day, a broad summary that does not describe conditions on any particular date.

If lower average rainfall is your priority, September is a conditional option: its mean daily rainfall is 2.43 mm/day. This is an average, not a promise of dry days, so keep flexible plans and rain protection in mind. For a cooler monthly mean, consider August, when the average is 22.1 °C; this does not specify daytime highs or the weather on an individual day.
Rain preparation is especially relevant for February, the month with the highest mean daily rainfall at 10.74 mm/day. The figure is not a monthly total and does not tell you how frequently rain falls, so it cannot guarantee conditions for outdoor sightseeing. For planning around average sunshine duration, December has the highest monthly mean at 11.07 hours/day, while June has the lowest at 8.54 hours/day. These averages can inform daylight outdoor plans, but sunshine hours are not day length and do not ensure clear skies; the lower-rainfall and cooler-average criteria may point to different months.
