The Best Time to Visit Vietnam

If you are short on time and just want the answer: mid-February to late April, or October to early November. Those two windows give you the best chance of dry weather across all three of Vietnam's climate regions on the same trip.

Everything beyond this paragraph is "it depends." Weather by month is the detailed grid.

The short answer

Lush green rice terraces (Sapa)	Late May to early Sept
Golden rice terraces (Sapa, Mu Cang Chai)	Mid-Sept to early Oct
Lowest crowds, lowest prices	Aug or early Sept
Festival atmosphere (Tet)	Late Jan to mid-Feb — check Tet dates
To avoid Tet shutdowns	Anything else

By region

The north (Hanoi, Ha Long, Sapa, Ha Giang). Best in October and November — dry, clear, cool. March and April are also lovely. December through February are dry but grey and cold, with Sapa genuinely cold (sometimes near-freezing). Summer is hot and wet, but it is also when the rice paddies are green.

The centre (Hue, Da Nang, Hoi An). Best from February to August. April and May are the sweet spot — hot, dry, calm sea, low risk. September through December is rough — typhoons, floods in Hoi An, choppy seas. The Hoi An lantern festival on the 14th of each lunar month is gorgeous year-round but check the rain forecast first.

The south (HCMC, Mekong Delta, Phu Quoc, Con Dao). Best November to April — dry, warm, predictable. May to October is the wet season, which sounds worse than it is: usually a single afternoon storm and then sunshine again. Phu Quoc in the wet season is half-empty and cheap.

The highlands (Da Lat, Buon Ma Thuot, Kon Tum). Best November to March — dry, sweater weather in the evenings. Summer is wet but green.

By activity

Beach. Follow the dry season for your chosen coast — Phu Quoc Dec–Apr, Da Nang Mar–Aug, Nha Trang Jan–Aug. Mui Ne is a kitesurfer's destination Nov–Mar.

Diving. Visibility is best at the end of the dry season — Mar–Jun off the central coast (Cham Islands), Dec–Apr at Phu Quoc and Con Dao.

Trekking and rice terraces. Sapa and Mu Cang Chai have two great looks: green (Jun–Aug) and gold (mid-Sep to early Oct). The trails are slippery in the wet season, especially July's leech-and-mud combo. Ha Giang loop on motorbike is best Sept–Nov.

Caves in Phong Nha. Open year-round, but the spectacular wild caves (Son Doong, Hang En, Tu Lan) only run tours Feb–Aug because of flooding.

Photography. October is the year's secret. The light is low and warm, the north is dry, the rice is golden in Sapa, Hoi An lanterns reflect on still puddles between rain showers. Hanoi's old quarter in October at 7am is the most photogenic the city ever gets.

City wandering. Hanoi: October, November, March. HCMC: December through February.

When NOT to go

Tết (Vietnamese New Year) — late January or February. Lovely if you understand what you are walking into; frustrating if you expected normal opening hours and trains. In 2026 it was 17 Feb. In 2027 it falls on 6 Feb. Plan around or commit to it — do not stumble into it.

Mid-October in the central coast — typhoon and flood risk is too high to bet a non-refundable booking on.

July in Sapa — wet, leeches, slippery, often clouded over.

Vietnamese public holidays for domestic travel — Reunification Day (30 Apr) and Labour Day (1 May) are the year's heaviest domestic travel period, plus Independence Day (2 Sep). Trains and flights book out, beach hotels triple their prices.

The low-season case

Vietnam off-season is one of the great deals in Southeast Asia. A 5-star Phu Quoc resort that runs 350 USD in January goes for 120 USD in July, with the pool to yourself. Hoi An in October between storms is empty, the tailors are bored, the river runs.

If your itinerary is flexible (an empty week here, a free Friday there), May, June and August are wildly underrated. Carry decent rain gear (see packing list) and accept that an afternoon thunderstorm is part of the deal.

Two-week trip blueprints

Classic, March: 4 days Hanoi → 2 days Ha Long → fly to Da Nang → 4 days Hoi An → fly to HCMC → 2 days HCMC → 2 days Mekong. Dry the whole way.

Classic, October: 4 days Hanoi → 2 days Ninh Binh → 3 days Sapa → fly to HCMC → 3 days HCMC → 2 days Phu Quoc. Skip the central coast.

Low season, July: 5 days Hanoi & Ha Long → fly to Da Nang → 4 days Hoi An (dry on the central coast) → fly to Phu Quoc → 4 days beach. Accept the south storms.

Whatever you choose, pair it with the right packing list.
