Climate overview
Temperature
Monthly mean temperatures are consistently close in the reported figures. The coolest monthly means are tied between March / April at 27.3 °C, and the warmest monthly mean occurs in September at 27.9 °C. These are averages for whole months, not daytime highs, so they do not describe the full range visitors may experience from day to day. Across the calendar-month means, the unweighted mean temperature is 27.6 °C. It provides a broad summary of the supplied monthly averages, rather than a day-weighted annual figure or a forecast for any particular visit.
Rain
Mean daily rainfall is highest in March at 8.36 mm/day and lowest in October at 2.94 mm/day. The figures are daily averages within each month, not monthly accumulation totals; the lower average does not guarantee dry days or indicate how frequently rain falls. The unweighted mean across the monthly daily-rainfall averages is 5.20 mm/day. It is useful as a broad point of reference, but it cannot tell a visitor whether rain will occur on a particular day.
Sunshine
Average daily sunshine duration reaches its highest level in September / November at 10.75 hours/day, a tie between the listed months, and its lowest in March at 9.76 hours/day. These averages can help with planning for daylight outdoor activities, but sunshine duration is not the same as day length. The unweighted mean of the monthly sunshine averages is 10.29 hours/day per day. This summarizes the supplied monthly figures; it does not promise a particular amount of sun on an individual day.

Make rain preparation part of the plan when travelling in March, when the mean daily figure is 8.36 mm/day.
For planning outdoor sightseeing around average sunshine, September / November has the highest mean daily sunshine duration at 10.75 hours/day, while March has the lowest at 9.76 hours/day.
