Da Nang and Hoi An share one climate, and it splits cleanly into three stretches: a dry, comfortable window, a hot-but-still-dry one, and a wet season with a specific flood risk worth planning around rather than glossing over. The short version: February–May is the sweet spot.
The short answer
| Season | Months | What it's like |
|---|---|---|
| The sweet spot | February–May | Dry season, before peak heat and humidity — reliable for both beach days and walking the Ancient Town. |
| Hot but still dry | June–August | Still technically dry season, but properly hot and humid — workable if you pack for it. |
| Wet & typhoon season | September–December | Rain and storm risk rises through the back half of the year, with real flood risk in October–November specifically — see below. |
If you only take one thing from this page: no strong preference either way → go February–May.
Why February–May
This is the region's dry season before the summer heat and humidity really set in, which makes it the most reliable stretch for both beach time in Da Nang and walking Hoi An's Ancient Town without wilting. It's the window we'd point most first-time visitors to.
June–August: still workable, just pack for it
June through August is technically still dry season, but it's hot and humid on the coast. Fine if you don't mind the heat — just plan for slower midday pace, more time in the water or air conditioning, and drink more than you think you need.
Hoi An's Ancient Town regularly floods in this window — it's a recurring seasonal pattern locals and hoteliers plan around, not a rare-disaster caveat. River water has reached several blocks up from the riverside in recent seasons, affecting ground-floor hotel rooms first. If your dates fall in October or November, book accommodation on higher ground, keep the rest of your itinerary flexible, and accept that the riverside streets could be underwater for a day or two.
September and December sit either side of that worst stretch — still wet-season months with rising storm risk through the back half of the year, but without October–November's specific, well-documented flood pattern.

Land already connected with an eSIM instead of hunting for a SIM at the airport, and don't travel uninsured — one medical bill abroad costs many times the premium.
