Most people who ask whether to do northern or southern Vietnam are really asking a scheduling question without realising it. The two halves have close to opposite good seasons, and getting that wrong costs more than picking the wrong region.
This page assumes you have roughly a week and cannot do the whole country. Prices are mid-2026 bands rather than quotes.
The short answer
- Go north if you are travelling in October, November, March, April or May, if landscape is what you came for, or if food is the organising principle of the trip.
- Go south if you are travelling between December and March, if you want beach time, if you are moving with small children, or if you want a week with minimal logistics.
- Go neither in late August and September if you have a choice: it is the wettest stretch in the south and the tail of the northern typhoon season.

Figures are long-run monthly averages for Hanoi and Ho Chi Minh City. If you are locked into December, our Vietnam in December guide has the detail.
Climate, and why it decides everything
The north has four real seasons because it sits far enough from the equator to feel the continental winter. Hanoi averages 20.1°C highs in January on 20 mm of rain, but with only 2.5 hours of sun a day, dropping to 1.5 hours in February. That statistic is the whole story: winter in the north is not wet so much as unlit, a low grey ceiling with a fine drizzle the Vietnamese call nom. Summer inverts it — 34°C in June with 265 mm of rain and typhoon risk from late May through early November.
The south has two seasons and no winter. Ho Chi Minh City sits between 31.7°C and 35.1°C in every month of the year; what changes is water. December to April is genuinely dry, bottoming at 5 mm in February with nine hours of daily sun. May to November brings 220 to 325 mm a month, but as heavy late-afternoon bursts rather than all-day rain, which is why southern wet season is far more travellable than the number suggests.
Landscape
The north is vertical. Limestone karst rises straight out of water at Ha Long and Lan Ha and out of rice fields at Ninh Binh; the northwest climbs to Fansipan at 3,143 m, with the terraced valleys of Sapa and the Dong Van karst plateau in Ha Giang beyond. It is the more photographed half for a reason.
The south is horizontal. The Mekong Delta is a 40,000 square kilometre plain of channels, floating markets and fruit orchards, and it is best understood by boat over two days rather than glimpsed on a day trip — the Cai Rang market at Can Tho is thinning year by year, and reaching it by 6 am is the difference between a working market and a souvenir stop. The drama is in islands, Phu Quoc and Con Dao, and in the delta's density of life rather than in relief. The trade-off is honest: the south has nothing that photographs like Ninh Binh, and the north has nothing that lives like the delta.
Food
Northern cooking values restraint. Broths run clear, seasoning is precise, black pepper does the work chilli does elsewhere, and Hanoi is where pho, bun cha and cha ca originate. Southern cooking is sweeter and rounder, built on sugar, coconut milk and fresh chilli, closer to Cambodian and Thai palates, and it produced banh mi and com tam. Southern pho arrives with a plate of herbs and bean sprouts and a hoisin bottle on the table; in Hanoi, none of that appears.
Neither is better. But if you are choosing a single half on food alone, the north's dishes are more distinct from one another and more tied to place.
Cost
The gap is narrower than the internet suggests. Ho Chi Minh City runs about 5 to 15 percent above Hanoi for comparable mid-range hotels, restaurants and tours, mostly on District 1 rents. Both halves sit well below Bangkok, and backpacker tiers are effectively identical.
Where the halves genuinely diverge is at the extremes. Phu Quoc holds the country's most expensive resort tier, and Con Dao is dear because supply is thin rather than because it is luxurious. A northern week, meanwhile, loads up on large discretionary line items: an overnight bay cruise, a Sapa trek with guide and transfers, or a Ha Giang loop. Those single bookings move a budget far more than the city-to-city difference does. Our Vietnam cost index has the sourced numbers, and the budget guide covers the daily tiers.
Getting around
The south is easier. Distances are short and flat, roads are good, Ho Chi Minh City's Metro Line 1 opened in December 2024 and carried more than 20 million passengers in its first year, and Phu Quoc and Con Dao are quick domestic hops. Long Thanh International Airport, the region's second major gateway, has been through phased trial operations with commercial service proposed from late 2026, which should ease Tan Son Nhat over time.
The north asks more of you. Sapa is around 380 km from Hanoi by sleeper bus or overnight train to Lao Cai; Ha Giang is a further commitment again; and mountain weather can close roads. Hanoi's metro is two partial lines, with the underground section to the main station targeted for 2027. Nothing here is hard, but the good stuff is further away.
Beaches and day trips
These two categories split the decision most cleanly. On beaches the south wins outright: 27 to 28°C water year-round off Phu Quoc, Con Dao's diving, and a 30-day visa exemption for direct arrivals to Phu Quoc who stay on the island. Northern sea temperatures fall to about 18°C from December to March, and the warm months are also when ferries get cancelled for typhoons.
On day-trip density the north wins just as clearly. Within three hours of Hanoi you have Ninh Binh, Ha Long and Lan Ha, Mai Chau and Perfume Pagoda, with Sapa reachable overnight. Within three hours of Ho Chi Minh City you have the Cu Chi tunnels, the near delta at My Tho and Ben Tre, and Vung Tau — fewer options and less variety. Our Hanoi versus Ho Chi Minh City comparison covers the two bases in detail.
What one week looks like
North: three nights Hanoi with a full day in Ninh Binh, two nights on a Lan Ha bay cruise or on Cat Ba, then either two nights in Sapa via the overnight train or a slower second pass at Hanoi's food. Tight but coherent, and everything runs off one base.
South: two nights in Ho Chi Minh City with a Cu Chi morning, two nights in the delta at Can Tho for the Cai Rang floating market at dawn, then three nights on Phu Quoc. Less driving, more swimming, and a genuinely restful week.
Limitations
The climate figures here are long-run monthly averages for Hanoi and Ho Chi Minh City, not forecasts, and they flatten a lot. A single Hanoi February can be clear and beautiful; a December in the south can be unseasonably wet. Workaround: treat the month table as a prior, then check a live forecast a fortnight out.
Three things this page does not cover. Central Vietnam — Hue, Da Nang, Hoi An, Phong Nha — is deliberately left out, and it has a third climate again, with a distinct September to December storm season, so a north-or-south framing genuinely omits a third of the country. Prices are mid-2026 bands, and we have not audited individual operators in either half. And Long Thanh airport's commercial start date has already moved more than once, so treat any 2026 date for it as provisional.
