Hội An Old Town in December

February through May gives you the sweet spot — dry weather, manageable heat, and fewer crowds than peak season. March hits the perfect balance with temperatures around 26°C and minimal rain. Avoid October and November entirely. The rainy season floods streets regularly, and humidity makes everything miserable. December through January brings cool weather but also peak tourist numbers. Here's something most guides won't tell you: typhoon season runs June through September, but Hội An sits in a protected bay that rarely sees direct hits. You might catch some rain, but flights don't typically get cancelled. The Full Moon Festival happens monthly and transforms the town into a lantern wonderland. But expect triple the crowds and book accommodation weeks ahead.
