TL;DR
September is the start of Nha Trang’s low season, but weekly and longer-range rain forecasts are unreliable. A forecast showing rain every day can still mean brief tropical showers with plenty of sun.
For a late-September trip, plan for possible rain rather than cancelling because of the forecast. In tropical weather, rain may fall in the mountains or a nearby area while the coast stays dry.
Long-range forecasts for Nha Trang often change and do not reliably show how long rain will last: a week marked as rainy may turn into a few short showers and sunshine, although the reverse is also possible.
Heavy rain was forecast for September 10–16, so travelers visiting around this period or later in the month should pack a rain jacket and keep indoor city plans as a backup.
