September is the peak of the wet season with 204 mm (8.0 in) across 16 rainy days and humidity at 82 percent, the highest of the year. Rain usually arrives as short, heavy afternoon or evening downpours rather than all-day drizzle, so mornings often stay clear.

The combination of 80 percent humidity and 30 °C heat makes midday feel heavier than the numbers suggest. If you travel in this window, plan outdoor activities before 1 pm.
