Vietnam in November: Weather, Crowds, Prices and Data

November is Vietnam's first high-season month. The south switches to dry, the north cools, and the central coast is still in flood season. Here is the plan and the data sizing.

Quick answer: For a two-week first trip, book the south and the north in November and skip the central coast: Phu Quoc and Saigon are dry from the first days of the month, Hanoi runs 20 to 26C, and Da Nang, Hoi An and Hue take around 415 mm of rain across 14 days (Highlights Travel, highlightstravel.com/vietnam/weather-in-november, undated page, figures are the source's own and not independently verified). Buy a Vietnam eSIM before you fly, because the ride app and the QR payment at the market both need data the moment you land.

Key takeaways

The country splits in three. November is dry and cool in the north (Hanoi 19 to 26C, 2 rain days) and dry in the south (Saigon 24 to 30C, 4 rain days), while the central coast gets around 415 mm over 14 rain days (Highlights Travel, highlightstravel.com/vietnam/weather-in-november, undated page, figures are the source's own and not independently verified).
Early November is the value window. Phu Quoc's dry season starts around 1 November but hotel calendars only flip to high-season pricing from mid-month, so the same weather is noticeably cheaper in the first ten days (Slow Vietnam, slowvietnam.com/vietnam-in-november, undated page, figures are the source's own and not independently verified).
Size data for the whole trip. A Vietnam eSIM cannot be topped up, so a two-week trip with maps, ride apps, messaging and an hour of 720p calls a day needs roughly 20 to 25 GB, not 5 GB. That range is our own rough estimate, based on typical app usage, not a measured carrier figure, and the per-app rates below are illustrative.
Cards are not taken everywhere. A QR wallet funded before you fly covers markets, cafes and small shops in Vietnam, and it is for foreign travellers only.

You are looking at flights to Vietnam for November and the two things you cannot settle are the weather and the money: is the north dry while the centre floods, and what happens when the taxi driver, the market stall and the beach bar all want cash or a QR code and your card is not welcome.

Is November actually a good month for Vietnam, or should I move my dates?

November is the start of Vietnam's high season (Slow Vietnam, slowvietnam.com/vietnam-in-november, undated page, figures are the source's own and not independently verified). Average national temperatures sit around 23 to 26°C (Highlights Travel, highlightstravel.com/vietnam/weather-in-november, undated page, figures are the source's own and not independently verified). The catch is regional: one third of the country is still in flood season.

So the answer depends on where you were planning to go, not on the month. If your itinerary is Hanoi, Ha Long Bay, Saigon, the Mekong or Phu Quoc, November is a strong pick and early November is the value window. If it is built around Hoi An, Da Nang and Hue, moving the dates to December or shifting the route south is the better call.

What does November weather mean for Hanoi, Saigon, Phu Quoc and Hoi An?

Domestic fares show the demand gap directly. Ho Chi Minh City to Hanoi in early November is quieter than the same route in late October and in late December, so early November is the least crowded of those three windows (Traveloka, traveloka.com/en-vn/flight/country/vietnam.vn, checked 06 October 2026).

On the ground, the arbitrage is in Phu Quoc. Comparing early-November dates against December shows the same weather for a quieter stay, because the rate calendars have not yet flipped (Slow Vietnam, slowvietnam.com/vietnam-in-november, undated page, figures are the source's own and not independently verified). Hanoi in early November is still shirt-sleeves autumn, and by the final week evenings want a real jacket, so front-loading a northern itinerary also buys the better weather.

Do I need an eSIM in Vietnam, or can I just buy a local SIM at the airport?

You need data on arrival either way. The question is whether you want it before you land or after you queue. A travel eSIM is bought and installed at home on Wi-Fi, keeps your home SIM in the phone for bank SMS, and turns on when you switch the travel line after landing. A local tourist SIM means a counter, a passport and a wait, and it replaces your home SIM unless your phone takes two physical cards.

Whichever you pick, size it for the whole trip. eSIM plans cannot be topped up, so a plan that runs dry on day six leaves you buying a second one. For a two-week November trip mixing maps, ride apps, messaging and a daily hour of calls, roughly 20 to 25 GB is the comfortable range, and the longer validity windows usually add only a little more per plan.

How much data does a two-week November trip use, and which plan fits?

A two-week trip through Vietnam in November is a two-region trip, and the data bill follows the region. Local Vietnam puts November in the north at 18-25°C in the day and 15°C or lower at night, dry and low humidity, and in the south at 25-32°C with showers that stop by mid-month. Both are map-and-message weather, not screen weather.

The table below is our own rough illustrative estimate, based on typical app usage, not a measured carrier figure. The per-app rates are illustrative rather than measured, and the totals are the sum of the rows. It assumes no livestreaming and no hotspot for a laptop.

Daily use	What it is	GB per day	14 days
Maps and ride apps	Grab, Google Maps, 2-3 hours of navigation	0.3	4.2
Messaging and photos	WhatsApp, Zalo, uploads to family	0.4	5.6
1 hour of 720p calls	Video call home, about 0.45 GB per hour at 1 Mbps	0.45	6.3
Cloud backup and updates	Phone photos, app updates on hotel Wi-Fi off	0.5	7.0
Total, mixed	No livestreaming, no hotspot for a laptop	1.65	23.1

Does mobile coverage hold up in Ha Long Bay, Sapa and the Mekong Delta?

Ha Long Bay: the Gulf of Tonkin haze lifts and storms are done in November, per Slow Vietnam. Signal holds on the mainland and near the harbour; expect gaps between the karst towers and on overnight boats.
Sapa and the far north: VinWonders puts Sapa at 10-18°C by day and 7-8°C at night in November, dry with minimal rain. Valley floors and town centres are covered; trekking routes and mountain passes drop out for stretches.
Mekong Delta: Slow Vietnam reports the delta riding post-flood lushness into the dry season. Coverage is good along the main channels and in Can Tho and My Tho; smaller canals and floating markets are patchy.
Central coast: November is peak flood season in Da Nang, Hoi An and Hue, with heavy rain events and swollen rivers into early December. Flooding can take local cells down for hours, so keep a downloaded map of your hotel and the nearest higher ground.

Frequently asked questions

Is November a good time to visit Vietnam?

Yes, if you pick the right half. The north and south are dry and mild, and Ha Long Bay has its clearest skies of the year. The central coast is in its wettest month, so route around Da Nang, Hoi An and Hue.

What is the weather like in Hanoi in November?

Dry and cool. Daytime highs run 19 to 26C with about 2 rain days for the month, and evenings get chilly by the final week. Pack a light jacket for the last days of the month.

Should I visit Hoi An or Da Nang in November?

Only with flexible plans. Both take around 415 mm of rain across 14 days (Highlights Travel, highlightstravel.com/vietnam/weather-in-november, undated page, figures are the source's own and not independently verified), and low-lying areas of Hoi An can flood briefly. December is a safer bet for the central coast.

How much data do I need for two weeks in Vietnam?

Roughly 20 to 25 GB. As a rough illustrative estimate, maps and ride apps use about 0.3 GB a day, messaging and photo uploads about 0.4 GB, an hour of 720p video calling about 0.45 GB, and cloud backup and app updates about 0.5 GB, which totals about 1.65 GB a day and about 23 GB over 14 days. That is our own rough estimate, based on typical app usage, not a measured carrier figure, and the per-app rates are illustrative rather than measured. Buy the whole trip in one plan because it cannot be topped up.

Can I use my card everywhere in Vietnam?

No. Hotels and larger restaurants take cards, but markets, small cafes and street food are usually cash or QR. Carry some dong and set up a QR wallet before you arrive.

Get your Vietnam eSIM before you fly

Install it on Wi-Fi at home, keep your home SIM for bank SMS, and switch the travel line on after landing. Paying in USDT instead? Open the app: new users get eSIM credit automatically in the eSIM tab, valid 12 months, in-app only. The shop page carries the current price.
