Da Nang in September

The month when the dry season hands over to the rainy one. Rain increases noticeably and the sea changes from day to day. Swim only at beaches with lifeguards. National Day on September 2 brings a holiday stretch around it.

Da Nang in September ran hot: 33°C by day and 25°C at night. By midday the shade was the best seat in town. About 13 days a month saw rain, enough that a wet-weather plan was worth having. A visitor in 2017 met 4 rain days; one in 2011 met 18. The average of 13 hid that gap.

27 days past 30°C made it a month for early starts and a long lunch indoors. Wet days did not mess around: about 32 mm each, the kind of rain that drives you into a doorway.
