Temperature
Monthly mean temperatures reach their highest point in August at 28.9 °C, while January / February share the lowest monthly mean, 25.8 °C. The reported mean across monthly means is 27.3 °C; it summarizes the calendar-month averages and is not a daytime maximum or a day-weighted annual average. For trip planning, these figures describe the broad temperature pattern, but they cannot indicate the conditions on a particular date.
Rain
Mean daily rainfall is highest in October at 4.97 mm/day and lowest in January at 1.20 mm/day. The unweighted mean of the monthly daily-rainfall averages is 2.68 mm/day.
