Ten-year averages for this calendar month. 16 rainy days, as the weather station at Kota Kinabalu (6 km away) counts them: its September average over 9 years, 2017–2026 (WMO 96471). A rainy day is one with at least 1 mm of rain.

Weather read at the waterfront, the centre, 5 km from the airport (BKI): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

How busy it gets

September: about usual. About as busy all year round.
