Climate and region of Nha Trang
Nha Trang is located in the southern part of Central Vietnam, along Vietnam’s eastern coastline. Although it’s geographically closer to Ho Chi Minh City, the climate in Nha Trang is more similar to that of Da Nang and Hoi An due to its position within Central Vietnam’s transitional climate zone. This region experiences a tropical savanna climate, influenced by seasonal monsoonal winds that create distinct dry and rainy seasons. The coastal location helps regulate temperatures, providing a steady sea breeze throughout the year.
Central Vietnam experiences more noticeable seasonal changes compared to Southern Vietnam’s year-round tropical climate. Nha Trang has a longer dry season and a shorter but more intense rainy season.
- Dry season of Nha Trang (January to August): Characterized by sunny days, low humidity, and minimal rainfall, ideal for beach activities and outdoor exploration.
- Rainy season of Nha Trang (September to December): Marked by increased rainfall, higher humidity, and occasional storms, though rain often comes in short, heavy bursts rather than continuous downpours.
Travel tip: Nha Trang’s climate doesn’t align with the rest of Vietnam. While September marks the start of the rainy season here, Northern Vietnam experiences cooler autumn weather, and Southern Vietnam remains hot with occasional showers. This variation is important to consider when planning a multi-destination trip across Vietnam.

Accommodations and availability
September is considered the start of the low season in Nha Trang, meaning fewer tourists and lower hotel prices. While some beachfront resorts still operate at high occupancy, many offer discounts, making it a good time to enjoy luxury accommodations at more affordable rates.
If you’re mainly visiting for the beach, it’s best to stay at a hotel near the main strip in the city, where restaurants, markets, and indoor attractions are easily accessible in case of rain. Resorts outside the city offer more secluded experiences, but it’s important to check weather forecasts if you plan to stay somewhere that relies on beach activities. Since it’s not peak season, last-minute bookings are easier, but for the best deals, booking in advance is still recommended.
