Vietnam in May: Weather and Event Guide

Da Nang, Vietnam in May

Overview

May is the transition month in Vietnam, marking the shift from spring to summer. During this time, the Northern region experiences heat waves and hot, dry weather, while the South gradually dives into the wet and humid season. Despite this sometimes unpredictable climate, May remains one of the best months for travel across the country.

Temperature & Humidity

In the North, May brings an end to the humid, misty conditions of April. The weather becomes hot yet comfortable, with temperatures in Hanoi ranging from 24°C to 32°C and a humidity level around 75%. With plenty of sunshine and pleasant conditions, May is ideal for visiting Hanoi and nearby attractions such as Halong Bay, Lan Ha Bay, and Ninh Binh.

As you head south, temperatures and humidity levels rise. In Hoi An, the average humidity reaches about 80%, which is notably lower than the 90% humidity typical from November to January. The low rainfall and extended hours of sunshine promise a delightful experience in the coastal cities of Da Nang, Nha Trang, and Quy Nhon.

If you plan to visit the southern regions, such as Ho Chi Minh City or the Mekong Delta, early to mid-May presents the best opportunity to enjoy the warm weather. Temperatures hover in the mid-30s degrees Celsius, similar to April and June, with minimal discernible differences among these months. What stands out in May in South Vietnam is the consistently lower humidity at 60-70%, providing a more comfortable experience compared to the North and Central regions, and occasional quick rain showers.

All in all, May is a fantastic time to explore Vietnam, thanks to the favorable weather conditions, reduced tourist crowds, and excellent travel deals.

What to Expect

• International Labor Day (April 30 - May 1) is a major holiday in Vietnam. Expect crowded beaches and airports during this festive time.
• Visitors are advised to book accommodation at least one month in advance to avoid overbooking during this busy period.
• Coastal resorts in central Vietnam, such as Da Nang, Hoi An, and Nha Trang, often provide special promotions starting May 5 as tourism slows down. Planning your visit smartly could save you up to 30% compared to April prices.

Best Destinations to Travel

With May being an excellent month for travel throughout Vietnam, you have the flexibility to choose your destination. As tourist traffic diminishes post-holiday, fantastic deals from hotels and resorts mean it's an ideal time to explore places you might otherwise find too expensive during peak season.

May offers the perfect environment for a cruise tour in Halong Bay

A Cruise Trip to Halong Bay

Halong Bay consistently ranks high on travelers' lists of must-see destinations. A cruise is the best way to explore its thousands of islets and grottos, with stops at notable sites like Titov Island and Surprise Cave. While a similar trip in late November could cost upwards of $500 due to less favorable weather, a May cruise may only cost half that and offer ideal conditions for swimming and kayaking. For a comprehensive experience, consider extending your trip to 3 days, possibly to include a day on Cat Ba Island to appreciate the stunning landscape fully.

A Relaxing Stay in Hoi An

Typically bustling from June to September and again from November to January, Hoi An sees fewer tourists in May, making it a prime time for a visit when the weather is remarkably pleasant. The brilliant sunshine, minimal rain, and beautifully spread-out old town present compelling reasons to plan your trip this month.

Beach Break in Nha Trang

Vietnam's beaches are usually crowded during the summer months as city dwellers flock to the coast for family trips. However, this is mainly a weekend trend. For a peaceful beach escape, consider traveling to Nha Trang during the weekdays, allowing you to enjoy its stunning white-sand beaches with fewer crowds. Rain typically does not arrive until the last days of May, making it a great spot to soak up the tropical warmth without the risk of severe sunburn. Additionally, many hotels and resorts offer significant travel deals during this month, ensuring you'll save on your May getaway.
