Ten-year averages for this calendar month. 15 rainy days, as the weather station at Sanya (Ya Xian) (9 km away) counts them: its September average over 9 years, 2017–2026 (WMO 59948). A rainy day is one with at least 1 mm of rain.

Weather read at Yalong Bay (or Sanya Bay), 11 km from the airport (SYX): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

How busy it gets

September: about usual. Busiest in August, November and December; quietest in February, May and June.
