May in Vietnam: climate by region

💡 In short:

In May, the rainy season begins in the north and south of Vietnam, while the center stays dry.
The central coast is best for the beach: Da Nang, Hoi An, and Nha Trang.
We checked the weather, rainfall, and sea temperature using data from Vietnam Tourism (09/2026).

Vietnam stretches nearly 1,650 km from north to south (Vietnam portal, as of 09/2026). On the same day, it can be raining in Hanoi while the sun shines in Nha Trang. In May, the heat builds, the first monsoon downpours arrive in the north and south, and the center enters its best season.

North: Hanoi, Halong, and Sapa

In the north, May opens the wet season. According to the Vietnam tourism portal (as of 09/2026), air temperatures in Hanoi reach 28-34 °C, and the month brings 145 mm of rainfall over 14 rainy days. Humidity stays around 78%.

Downpours usually arrive in the afternoon and end quickly. In the morning you can fit in a tour, and by evening it will be dry again. Bring an umbrella and a light jacket.

Ha Long Bay karst rocks and a boat on the water

In Ha Long Bay it's hotter and more humid: 25-32 °C and 160 mm over 15 rainy days (as of 09/2026, source). Cruises are sometimes canceled due to thunderstorms, so book a tour with flexible cancellation.

Sapa sits in the mountains and behaves differently. Here it's 18-26 °C, with up to 220 mm of precipitation and 18 rainy days (climate summary, 09/2026). Nights are cool, and mountain trails get muddy and slippery.

Who it's for / Not for: For those who like cool weather and trekking. Not for those coming for the beach.
The catch: Afternoon downpours and wet shoes on mountain trails.

In Hanoi, it's convenient to look for accommodation near the Old Quarter. Compare options in advance: Hanoi hotels on Trip.com.

Central Vietnam: Da Nang, Hoi An and Nha Trang

The central coast offers the best beach conditions in May. According to Vietnam Tourism (09/2026), Da Nang sees 27-35 °C and only 70 mm of rain over 7 rainy days. Showers are rare and short, and the sun shines up to 9 hours a day.

My Khe Beach sand and Da Nang high-rises

On some days the air heats up to 38 °C, so walk in the morning and evening (Vietnam portal, 09/2026). During the day, stay by the sea or in air-conditioned cafes. The water near the shore is around 28 °C.

Hoi An Old Town street with yellow buildings

Hoi An is right next to Da Nang, and the weather is almost the same: 26-35 °C and 75 mm over 8 rainy days (as of 09/2026, temperature and precipitation). Evenings are warm, so dinner outdoors won't ruin your night.

Nha Trang in the southern part of the central coast remains one of the driest spots on the coast. Rainfall is low here, the sea is warm, and you can swim all day. If you're specifically after a tan, plan your days here.

Who it's for / Not for: For beach vacations and those who handle heat well. Not for those who struggle in direct sun.
The catch: Extreme daytime heat, especially in Da Nang and Hoi An.

Beachfront hotels in Da Nang and Hoi An get booked early. Check dates and prices: See Da Nang hotels on Trip.com.

South: Ho Chi Minh City, Phu Quoc and Mui Ne

In the south, May kicks off the rainy season. According to Vietnam Tourism (09/2026), Ho Chi Minh City sees 26-34 °C, 210 mm of rain over 19 rainy days, and humidity around 82%.

Downpours arrive in the afternoon and pass quickly. Use the morning for walks and markets, then spend the afternoon having coffee under a roof. That way you won't lose the day.

Phu Quoc is the rainiest of all: 27-33 °C, up to 280 mm and 20 rainy days (as of 09/2026, island overview). The sea gets choppy, but sunny windows still happen. Prices are lower than in high season.

Mui Ne and Phan Thiet are milder. Rain is less frequent here, and the wind makes the weather more pleasant for kitesurfing. For calm swimming, choose the morning while the sea is quiet.

Who it's for / Not for: For those who want to spend less and don't mind short downpours. Not for those looking for a guaranteed dry beach.
The catch: High humidity and evening downpours.

⁉️🤔 Frequently asked questions

Can you swim in Vietnam in May?

Yes, you can swim. The central coast is the most comfortable, where the sea is warm (as of 09/2026, the sea in May). In Da Nang, Hoi An and Nha Trang, beach season is in full swing, and rain is rare and short. On Phu Quoc the waves are stronger, but you can still swim on sunny days. For the north, it's better to plan for the beginning of the month.

How many rainy days are there in May?

The most rainfall is in the south: Ho Chi Minh City has about 19 rainy days, Phu Quoc 20 (number of rainy days, 09/2026). In the north, Hanoi has roughly 14 days with rain. In the center there is little rain, just 7-8 days, so beach holidays there are more reliable. Showers are usually short and come after lunch, so the evening stays free.

What to pack?

Bring light, breathable clothing, a raincoat or compact poncho, sandals, and sunscreen. For the north, waterproof trekking shoes and a warm sweater for evenings in Sapa will come in handy. Hotels and buses run air conditioning, so pack a light jacket in your backpack. Don't forget mosquito repellent.

When is the best time to go to central Vietnam?

The best time for the center is February-May. In May it's still dry but already very hot, with sunshine up to 9 hours a day (central Vietnam climate, 09/2026). In June and July the heat intensifies, but there is almost no rain. From September, typhoons and heavy rains arrive, so beach season closes by autumn.

Are there typhoons in May?

Rarely. Typhoon season in Vietnam starts in June and intensifies toward August-November. In May, isolated tropical storms are possible, but this is not a high risk and not a reason to cancel your trip. Keep an eye on the forecast if you're heading to the central coast, and choose accommodation with flexible cancellation.
