September Weather in Denpasar: A Closer Look

September is widely considered one of the best months to visit Denpasar. The dry season continues with only 47mm of rainfall over 8 days, but the peak tourist crowds begin to thin after the school holiday exodus. Temperatures stay at 31°C highs and 23°C lows with humidity at 72%. Sea temperatures hover around 27°C, and the water remains exceptionally clear for diving. The UV index climbs back to 7 as the sun angle shifts. The strong southerly trade winds ease slightly through September, making outdoor dining and beach time even more comfortable. This is essentially the same weather as July-August but without the surcharges and queue times. The Bali International Airshow takes place at the end of September near Ngurah Rai Airport — a multi-day aviation exhibition that draws significant crowds to the Nusa Dua area. Prices at hotels and restaurants typically drop 20–30% compared to peak August rates.
