Best Vietnam Islands in December 2026: Weather Guide

December Weather Across Vietnam’s Islands

The pattern is driven by the northeast monsoon, which brings rain to the central coast from roughly September to December and cooler, drier weather to the north. The south, including Phu Quoc in the Gulf of Thailand, is sheltered and enters its dry season around November. For official forecasts closer to your trip, check Vietnam’s National Centre for Hydro-Meteorological Forecasting.

1. Phu Quoc: The December Winner

December is one of Phu Quoc’s best months: dry, sunny, typically in the high 20s °C, with calm seas along the west coast. Long Beach is ideal for sunsets, while Bai Sao and Bai Khem on the south-east coast offer powder-soft sand, though they can catch more wind at this time of year.

For luxury stays, Regent Phu Quoc on Long Beach offers some of the island’s most refined villas and dining, JW Marriott Phu Quoc Emerald Bay is a playful, design-led resort in the south, and La Veranda brings colonial-era charm in a smaller setting. Our list of the best beachfront resorts in Phu Quoc has more options.

Phu Quoc allows visa-free stays for many foreign visitors arriving directly on the island; for other routes, Vietnam’s official e-visa portal handles applications. Beyond the beach, December’s calm water is ideal for a private boat trip to the An Thoi archipelago at the island’s southern tip, where snorkelling around small islets is at its clearest of the year. The Hon Thom cable car, one of the longest over-sea cable cars in the world, connects the south of the island to Hon Thom, and the Phu Quoc National Park in the north offers forest walks before the heat of the day. Duong Dong’s night market and the island’s pepper farms and fish-sauce houses add local flavour, and sunset on the west coast is reliably spectacular at this time of year. Book early for the last ten days of December, when the island’s luxury resorts are at their busiest and most expensive.

2. Con Dao: Wild and Beautiful, With Caveats

The Con Dao archipelago lies off the southern coast and is quieter and more protected than Phu Quoc. In December it is mostly dry, but the northeast monsoon can bring strong winds and rough seas. Flights from Ho Chi Minh City are the most reliable way in, as ferries can be suspended in bad weather.

Six Senses Con Dao is the island’s standout luxury resort, with villas on a long private beach. December is not turtle nesting season, which is mostly mid-year, but hiking, history and quiet beaches remain rewarding. Read our Con Dao honeymoon guide if you are visiting as a couple.

3. Ninh Van Bay and the Nha Trang Coast

Ninh Van Bay, a sheltered peninsula near Nha Trang reachable only by boat, is home to Six Senses Ninh Van Bay and An Lam Retreats. Both are superb — but December is typically the tail end of the central coast’s rainy season, with heavy showers and rougher sea transfers. If December is your only window, choose a resort where you would happily spend rainy days at the spa. Otherwise, wait for January to April. Our Ninh Van Bay luxury resorts guide and Phu Quoc vs Nha Trang comparison explain the trade-offs.

4. Quy Nhon and the Cham Islands

Quy Nhon has become one of Vietnam’s most stylish coastal escapes, with resorts such as Anantara Quy Nhon Villas and Zannier Hotels Bai San Ho. But December is still usually rainy here, with strong waves. The Cham Islands off Hoi An are even more affected: boat services to the islands are often suspended in rough weather during the rainy months. Both are far better from about February or March. See our Quy Nhon honeymoon guide for timing ideas.

5. Lan Ha Bay and Cat Ba: A Winter Alternative

In the north, December is dry and cool, often around 15–20 °C, with soft mist over the limestone karsts of Lan Ha Bay and neighbouring Ha Long Bay. It is not beach weather, but it can be atmospheric for an overnight luxury cruise, kayaking in calm lagoons and seafood dinners on deck. Pack layers and treat it as a scenic add-on to Hanoi rather than a beach stay. Our luxury resorts on Cat Ba guide covers where to stay on land.

Planning Christmas and New Year in Vietnam

The period from about 20 December to early January is peak season for southern resorts. Expect minimum stays of three to five nights, compulsory gala dinners on 24 or 31 December at many properties, and rates well above November levels. Book flights to Phu Quoc early, as domestic routes from Hanoi and Ho Chi Minh City sell out. If you are comparing destinations across Asia for the holidays, our guide to the best island resorts for New Year’s Eve offers alternatives.

Families should reserve connecting rooms or multi-bedroom villas months in advance, as these sell out first, and check whether kids’ clubs run extended holiday programmes. If you want a quieter celebration, smaller boutique properties often host relaxed beach dinners instead of large gala events, and some allow you to opt out of the compulsory dinner for a lower rate. Airport transfers on Phu Quoc are short, but traffic around Duong Dong increases sharply over the holidays, so build in extra time for departure days. Trying to avoid the crowds? The first half of December often brings similar weather in Phu Quoc at noticeably lower prices.

A Seven-Night December Itinerary

• Nights 1–2: Hanoi and Lan Ha Bay — a city night followed by an overnight cruise in the cool, misty bay.
• Nights 3–7: Phu Quoc — fly south for five nights of beach time, a boat trip to the An Thoi islands and the Hon Thom cable car.

If you prefer to stay in one place, simply spend all seven nights on Phu Quoc and split them between two resorts — for example, a lively Long Beach base followed by a secluded villa in the south.

Couples with longer trips can add two nights in Con Dao by flying via Ho Chi Minh City, keeping the schedule flexible in case of wind.
