May marks the turn from spring to summer across Vietnam. Crowds from the late-April holidays thin out after the first days of the month, prices are often more relaxed than in winter, and the central coast enters its best season. The trade-off is heat, and the first rains in the north and south.
May weather at a glance
| Region | What to expect in May | Our verdict |
|---|---|---|
| Hanoi, Ninh Binh | Hot and humid; afternoon thunderstorms more frequent | Good with early starts |
| Halong and Lan Ha Bay | Warm sea, often clear; occasional storms | Good, and swimming season begins |
| Sapa, Mu Cang Chai | Warm days, cool nights; terraces being flooded and planted | Good for walking and photography |
| Hue, Hoi An, Da Nang | Hot, dry and sunny; calm sea | Excellent |
| Nha Trang, Quy Nhon | Dry and sunny | Excellent for beaches |
| Ho Chi Minh City, Mekong Delta | Hot; rainy season begins, usually with short afternoon showers | Good, with flexible afternoons |
| Phu Quoc | End of the dry season; the west coast becomes rougher later in the month | Fair; the central coast is a better beach choice |
The centre is the star
From May to August, the central coast is at its driest and sunniest, just as the north and south become wetter. Hoi An’s beaches are calm, boat trips to the Cham Islands run, and the evenings in the Old Town are warm and lively. Hue is very hot by midday, so we visit the citadel and the tombs early. In summer we plan the region around the heat: sightseeing early, beach and pool at midday, the Old Town in the evening.
The north: green and steamy
Hanoi is hot and humid, and short, heavy afternoon storms become common. Ninh Binh’s rice fields are green, Halong Bay is warm enough to swim, and the mountains around Sapa and Mu Cang Chai are pleasant, with terraces being flooded and planted, which creates mirror-like reflections. See Sapa, Ha Giang or Mu Cang Chai.
For the water-filled terraces of May, see our Mu Cang Chai private trips, with routes from Hanoi and suggested trip lengths.
The south: the rains begin
The rainy season usually starts in the south during May. Downpours tend to be heavy but brief, often in the afternoon, so mornings remain good for sightseeing in Ho Chi Minh City and the Mekong Delta. Phu Quoc’s dry season ends, and for a beach finish we usually prefer the central coast from now until August.
A May route we like
- Hanoi (2 nights) and Ninh Binh (1 night).
- Halong or Lan Ha Bay (1–2 nights), with swimming and kayaking.
- Hue (2 nights), then Hoi An (3–4 nights) with beach time.
- Ho Chi Minh City and the Mekong Delta (2–3 nights), sightseeing in the mornings.
Practical tips
- Start days early and rest at midday; the heat builds quickly.
- Carry a light rain jacket or umbrella in the north and south.
- Drink plenty of water and use high-factor sun cream.
- Pagodas are often decorated for Buddha’s birthday, which falls in late spring according to the lunar calendar.
For the rest of the year, see Vietnam in April and the month-by-month guide.

Where to go and where to think twice in May
Good choices in May:
- Hoi An, Da Nang and Nha Trang for beach days and calm seas
- Hue, which is hot but dry
- Halong Bay for warm-water swimming from the cruise
Think twice about:
- Planning long outdoor afternoons in Hanoi or Saigon: build in a midday break
- Counting on dry days in the Mekong Delta later in the month
- Travelling on 30 April to 1 May without confirmed bookings
