Central Vietnam climate
Before we explore the weather in May, it’s helpful to understand the broader climate of Central Vietnam, as it plays a major role in shaping travel conditions. Central Vietnam has two distinct climate zones due to its mix of coastal and highland geography:
- The Central Coast, featuring Hoi An, Da Nang, Nha Trang, and Hue, follows a tropical coastal climate, where seasons are defined by rainfall.
- The Central Highlands, including Dalat, Dak Lak, and Kon Tum, have a cooler climate influenced by elevation, rather than the coastal monsoons.
This means that May brings different weather conditions depending on which region you visit.
Central Coast (Hoi An, Da Nang, Nha Trang, Hue)
May marks the transition toward the rainy season, with hotter temperatures and increased humidity. While rain showers become more frequent, the true rainy season has not yet arrived.
- Dry Season: January – August
- Rainy Season: September – December
Central Highlands (Dalat, Dak Lak, Kon Tum)
The rainy season begins in the Central Highlands, bringing cooler daytime temperatures and occasional showers, though heavy rainfall is still uncommon in early May.
- Dry Season: November – April
- Rainy Season: May – October
Important: Central coast guide for May
As already explained, Central Vietnam consists of two climate zones: the Central Coast, where popular destinations like Hoi An, Da Nang, Nha Trang, and Hue are located, and the Central Highlands, home to Dalat, Dak Lak, and Kon Tum, which have a cooler, more temperate climate. Since these regions experience different seasonal patterns, this guide will focus on the Central Coast, as that’s what most travelers are looking for.
The coastal region is a major tourist destination, where the weather significantly affects travel plans, especially for beach activities. If we were to include the Central Highlands in detail, it would make this guide overly complicated.
For those traveling to the Central Highlands, we recommend checking our specific weather guides:
These guides provide detailed weather information for Dalat and other destinations in the Central Highlands in May. Keeping this guide focused on the Central Coast allows for a clearer overview while still offering resources for travelers heading inland.
