Climate overview
Temperature
Monthly mean temperatures are highest in October, at 27.4 °C, and lowest in February, at 25.8 °C. These are averages for each month, not daytime maximum temperatures, so they describe the general monthly level rather than the hottest conditions a visitor might encounter. The unweighted mean of the monthly temperature means is 26.7 °C. It provides a broad summary across the calendar months; it is not a day-weighted annual average and does not show how temperatures vary from day to day.
Rain
Mean daily rainfall is highest in February, at 11.20 mm/day, and lowest in August, at 1.80 mm/day. The figures are daily averages for those months rather than monthly rainfall totals, and the lower average does not guarantee rain-free days. Across the calendar months, the unweighted mean of monthly mean daily rainfall is 6.19 mm/day. This is a summary of the monthly averages, not a day-weighted annual mean or a measure of how often rain falls.
Sunshine
Mean daily sunshine duration is highest in September, at 10.79 hours/day, and lowest in January, at 7.84 hours/day. These values can help with planning outdoor time, but sunshine duration is not the same as daylight length and does not promise clear conditions on a given day. The unweighted mean of the monthly mean daily sunshine durations is 9.46 hours/day. It summarizes the calendar-month averages without weighting them by the number of days in each month.
