This guide explains what Vietnam is like in May: the weather, how busy it is, what to plan and who the month suits. Figures are typical values from our destination research, so check a forecast before you travel. Weather differs sharply by region, so read the notes for the north, centre and south.
May marks the shift to the wet season. Highs reach about 34°C and lows about 25°C, with about 170 mm of rain and humidity near 78 percent. Heat and humidity rise in the north and south. Central Vietnam is usually more favourable, so Hoi An and Da Nang are often the better choices. Showers are likely, but they rarely last all day, so plan around them with flexibility.
May suits budget-focused and flexible travellers who accept heat and humidity in exchange for lower prices. It also suits those who want Hoi An and Da Nang rather than the full route. It is a weaker choice for a cruise-first trip, or for travellers who want dry, cool walking weather.
May is far wetter than April, at about 170 mm instead of about 55 mm, and more humid. It is a few degrees warmer overnight. It is not as wet as June to September. For price-sensitive travellers, May can be a sensible trade-off against the dry months. See also April and June.
Several travel sources note that May can be budget-friendly for flights and accommodation. The trade-off is weather, so keep days flexible and avoid packing tight transfers. Central Vietnam gives you the highest chance of dry hours, so a Hoi An and Da Nang focus works well. If you still want the north, choose an overnight cruise with a refundable option, and check storm forecasts before you go. Our packages are land-only, so flights are booked separately, and Indian travellers need an e-visa, covered in the Vietnam visa guide for Indians.
