Temperature
Monthly mean temperatures remain fairly steady across the year. The lowest monthly mean occurs in December at 25.1 °C, while the highest is shared by May / June at 26.5 °C.

Rain
Mean daily rainfall is highest in November, at 14.88 mm/day.

The unweighted mean across the monthly daily-rainfall means is 10.25 mm/day; neither figure gives a forecast for an individual visit or the number of rainy days.
