Planning a trip to Vietnam and wondering when is rainy season in Vietnam? You’re not alone. Vietnam’s long, S-shaped map crosses multiple climate zones, so rain falls at different times across the country. Understanding the Vietnam rainy season 2025 is key to choosing the right route, packing smartly, and enjoying your adventure regardless of the weather.
In this guide, I’ll walk you through when and where the rains fall, share tips for traveling during the wet months, and show how to make the most of your trip — even under a few showers.
How Vietnam’s Rainfall Works
Vietnam’s climate is shaped by two large monsoon systems. From May to October, the southwest monsoon brings moisture from the Indian Ocean, creating heavy rains in many regions. Meanwhile, from November to April, the northeast monsoon brings drier air—especially in the north.
Because of its geographic diversity, rainy season in Vietnam doesn’t occur uniformly. The North, Central, and South all have their own rhythms:
-
In the North, including Hanoi and Halong, heavy rain generally occurs from May to September.
-
In Central Vietnam (Hue, Danang, Hoi An), the rainy season often sets in from September to December, with October–November being the wettest months.
-
In the South, including Ho Chi Minh City and the Mekong Delta, rainfall is heaviest from May to November, with daily afternoon downpours common.
So, when you ask “when is rainy season in Vietnam?”, the answer is: it depends which region you plan to visit.
Rain Patterns by Region
Northern Vietnam (Hanoi, Halong, Sapa)
From May to September, the north faces frequent and sometimes heavy rain—especially in July and August. These showers often arrive in the afternoon or evening
This period can also bring thunderstorms or heavy downpours lasting a few hours. Still, mornings may stay relatively dry, so some sightseeing can be squeezed in.
Central Vietnam (Hue, Da Nang, Hoi An)
The central region’s rainy season typically begins later — around September — and continues into December.
October and November often bring typhoons and flooding, making sea conditions rough and some roads risky. But off-peak periods (Sept or December) can still deliver dramatic skies, fewer tourists, and lower rates.
Southern Vietnam & Mekong Delta
The South has one of the longest rainy seasons: May through November.
Rainfall here tends to be intense but short-lived — often lasting one or two hours in the afternoon, then giving way to clear skies. As a result, many travelers still enjoy mornings for sightseeing.
