Vietnam in October: ✅ excellent in the north, ❌ best avoided in the centre. Hanoi is coming out of the rainy season (155 mm, 6.1 in, 11 rainy days) and Halong Bay becomes one of the driest places in the country. At the same time, the centre receives its heaviest rains of the year: 773 mm (30.4 in) in Hue and 628 mm (24.7 in) in Da Nang, with typhoons and floods possible. The south is still wet (340 mm, 13.4 in in Ho Chi Minh City). The right formula: the north, possibly combined with the south by air, skipping the centre.
October is the month when Vietnam is at its most contrasted: it rains more than five times as much in Hue as in Halong Bay. To help you choose, we gathered the official normals for eight stations from north to south and calculated, for each, the rainy days to expect over a week. To compare with the other months, see our page on the best time to visit Vietnam.

Destination de Voyage calculation from these normals: over a 7-day stay in October, you can expect on average 2 days with rain in Halong Bay and 3 in Hanoi, against 5 in Hue and Da Nang. Hue gets 5.4 times as much rain as Ha Long. It is also the first month when nights cool down in the north (22.8 °C, 73 °F, in Hanoi, 13.7 °C, 57 °F, in Sa Pa), while the south keeps 25 °C (77 °F) at night.
October, the turning point of the year: September, October, November
| Station | September | October | November |
|---|---|---|---|
| Hanoi | 228 mm (9.0 in) | 155 mm (6.1 in) | 61 mm (2.4 in) |
| Ha Long (Bai Chay) | 276 mm (10.9 in) | 143 mm (5.6 in) | 39 mm (1.5 in) |
| Hue | 411 mm (16.2 in) | 773 mm (30.4 in) | 642 mm (25.3 in) |
| Da Nang | 351 mm (13.8 in) | 628 mm (24.7 in) | 448 mm (17.6 in) |
| Ho Chi Minh City | 490 mm (19.3 in) | 340 mm (13.4 in) | 128 mm (5.0 in) |
Destination de Voyage calculation: between September and October, rain falls by 32% in Hanoi and by 48% in Ha Long, but nearly doubles in Hue (+88%). In the south, October is drier than September (490 to 340 mm, 19.3 to 13.4 in, in Ho Chi Minh City), but the real improvement comes in November (128 mm, 5.0 in). In short: in the north, the second half of October is safer than the first; in the centre, no part of the month is reliable.
Which itinerary in Vietnam in October?
| Itinerary | In October | Advice |
|---|---|---|
| North only (Hanoi, Halong, Ninh Binh, Sapa) | ✅ The best choice | Halong on a one- or two-night cruise; Sapa cooler and still wet |
| North + south by air | ✅ A good formula | The south is still wet in October: keep the Mekong Delta for the end of the trip |
| Full north-to-south circuit | ⚠️ Possible with reservations | Cross the centre by air; Hue and Hoi An can be flooded |
| Centre (Hue, Hoi An, Da Nang) | ❌ Avoid | Peak of rains and typhoons; prefer February to August |
| Beach on Phu Quoc | ⚠️ Not yet | 354 mm (13.9 in) and about 22 rainy days; wait for December |
Region by region
Hanoi, Halong Bay and Ninh Binh
This is the region to favour. In Hanoi, afternoons go from 31.9 °C (89 °F) in September to 30.4 °C (87 °F), with less oppressive air. Halong Bay averages 9 rainy days, against 14 in September and 19 in August, and nearly 6 hours of sunshine a day: it is one of the best periods for a cruise. The UK FCDO advises considering safety standards carefully before an overnight boat trip on Halong Bay, as overcrowding and poor safety standards have led to accidents in past years (GOV.UK, updated 21 September 2026). See also our page on Hanoi.
Sapa and the northern mountains
At 1,570 m (5,151 ft), Sa Pa stays wet in October (201 mm, 7.9 in, about 19 rainy days) but half as wet as in July. Highs fall to 19 °C (66 °F) and nights to 13.7 °C (57 °F): a warm layer is essential.
Hue, Hoi An and Da Nang: the hardest month
October is the wettest month of the year in Hue (773 mm, 30.4 in) and Da Nang (628 mm, 24.7 in), with about 20 rainy days and 4 to 5 hours of sunshine a day. The UK FCDO says the rainy season in central Vietnam runs from October to December, that seasonal flooding occurs in October and November in central Vietnam, and that roads can be blocked by mudslides and landslides (GOV.UK, updated 21 September 2026). It adds that the tropical storm season runs from May to November, with cyclones affecting the eastern coastal regions. If the centre is unavoidable, keep flexible bookings and follow weather alerts. See our page on Hoi An.
Ho Chi Minh City, the Mekong and Phu Quoc
The south is still in the rainy season (340 mm, 13.4 in, and 16 rainy days in Ho Chi Minh City), but showers often fall late in the day and sunshine exceeds 5.8 hours a day. For the Mekong Delta, the UK FCDO notes that seasonal flooding is also common in the Mekong River Delta regions. Phu Quoc remains very wet (354 mm, 13.9 in).
Things to do in Vietnam in October
- A cruise in Halong or Lan Ha Bay: the driest period since spring.
- Ninh Binh by bike and boat: karst landscapes, in a drier period than summer.
- Hanoi’s Old Quarter: walks that are more pleasant than in summer.
- Hiking in Sapa or Ha Giang: with rain gear and a warm layer.
- The Mekong: markets and canals, with a plan B in case of showers.
- To avoid: a beach stay in the centre or on Phu Quoc, and any boat or mountain excursion on weather-alert days.
Festivals in October
The Mid-Autumn Festival (Tet Trung Thu) takes place on the 15th day of the 8th lunar month, in September or early October depending on the year: check the date for your year of travel. In Hoi An, the lantern night takes place every month at full moon, but it can be disrupted by floods in October. Dates of lunar festivals change every year: check with the Vietnam National Authority of Tourism.
Crowds and prices in October
October is a month of strong demand in the north, according to our calendar, and of low crowds in the centre and south. Book flights and cruises in advance.
What to pack for Vietnam in October

Entry requirements and safety
Visa, passport and entry rules differ for US and UK citizens and change regularly: see our guide to entry requirements for Vietnam.
On safety, both the UK FCDO and the U.S. Department of State note that you may need a permit or permission from local authorities to visit areas close to the border (GOV.UK, updated 21 September 2026; travel.state.gov, last updated July 2, 2026). On the road, the UK FCDO says helmets are compulsory for drivers and passengers on two wheels, and the U.S. Department of State strongly discourages riding a motorcycle or scooter in Vietnam (last updated July 2, 2026).
If October does not suit you
Neighbouring months: November is even drier in the north (61 mm, 2.4 in in Hanoi) and the south dries out, but the centre stays very wet. If your itinerary goes through the centre, prefer summer: Vietnam in August is dry and sunny there. If you are torn between neighbours, read Thailand or Vietnam.
Other destinations in October: Bali in October, at the end of the dry season, or Japan in October. All our ideas: where to go in October. To organise your stay: our Vietnam travel guide.
