Should you visit Ho Chi Minh City during rainy season?
It can still work. Rain in the wet season often falls in short, intense bursts rather than all-day washouts, prices are lower and crowds thinner. But expect high humidity, disrupted boat trips and island transfers, and the occasional flooded street — September in particular is best avoided.
