When Is Monsoon Season in Vietnam? A Guide for Vietnam Package Tours

What Is the Monsoon Season in Vietnam?

What is a Monsoon and Why It Matters in Vietnam

And a monsoon is more than simply rain; it’s a dramatic change in wind direction tied to temperature differences between the land and the sea. In Vietnam, these winds are life itself. They influence the climate, determine where rain will fall, and decide whether your visit will be hidden in mist, bathed in sunshine, or deluged under tropical deluges. 

Vietnam is situated in the tropical monsoon zone and is affected by two main monsoons:

• The Northeast Monsoon (Winter Monsoon):  November to April, characterised by dry cold air. Crossing the open sea before it arrives in Northern Vietnam and Central Vietnam, this air receives moisture, creating cold, wet conditions, particularly through October and November. Think drizzles in Hanoi, cold fog in Sapa, and gray skies over Ha Long Bay.
• The Southwest Monsoon (Summer Monsoon): It operates between May and October and is characterized by the import of warm, humid air from the Indian Ocean and the Gulf of Thailand. This monsoon brings the wet season to Southern Vietnam and along the Mekong Delta and the Central Highlands. Anticipate tropical downpours that may be fierce but are usually short-lived in Ho Chi Minh City, verdant rice paddies in the delta, and green hills unfurling beneath monsoonal clouds.

Monsoon Timeline Across Vietnam’s Three Regions

Due to the elongated shape of Vietnam, When Is Monsoon Season in Vietnam is extremely region dependent, and you’ll need to know which part of the country you’re in in order to properly plan your activities. Here’s a clear breakdown:

North Vietnam Monsoon Season: Four Seasons, From Mist to Storm

Winter Monsoon (Nov – Apr): Cold, Foggy, and Peaceful

From November to April, the northeast monsoon, blowing in from Siberia, lifts cold, dry air into the airspace above the lake. Early winter is cool and dry, but late winter (January to March) may become damp and misty with light rain, particularly in Hanoi, Sapa, and Ninh Binh.

• It’s cost them an average of 10°C degrees for he complete season.
• It’s Tet festival season, a festival time for experiencing the local culture.

Pack: warm clothes, rainproof layers, and shoes with grip.

Summer Monsoon (May – Oct): Hot, Humid, and Rainy

This is high summer in Vietnam, and also high rainy season in Vietnam for the north. The southwest Monsoon plays an important role as the heavy rain it carries falls in July and August.

• The humidity and temperature are expected to exceed 35°C.
• Rain comes in short, heavy bursts, heavenly for dramatic skies and lush green landscapes in Ha Giang or Mu Cang Chai.

Perfect for photographers and thrill-seekers, but don’t take any remote treks during a storm.

Central Vietnam Monsoon Season: Hot Summers, Stormy Autumns

Dry Season (February – August): Scorching Sun & Bright Days

February through August is the dry season in Central Vietnam, characterized by long sunny days with very little rain. If you’re visiting in June to August, you’re in for a sizzler: It’s hot and dry, with temperatures of up to 42°C, particularly in Hue and Da Nang.

If you’re mapping out your summer in Vietnam, this is going to be a favorite, but plan for the heat! Rainy Season (September – January) – Typhoons, Sudden Storms

Here comes the twist. When other areas begin to cool off, Central Vietnam heats up for its monsoon season, and it’s no joke. During September to January, this region is hit by severe typhoons, floods, and heavy rains; the worst occur in October and November.

• Da Nang and Hoi An, coastal cities, are easily inundated.
• Areas inland, such as Hue, may experience storm surges and river flooding.

Why so dramatic? It’s because of what the Truong Son Mountains do: They function as a wall, holding moisture brought from the sea and releasing it in the shape of downpours on the coast. Conversely, areas on the lee side of the range may remain drier, leaving sharp microclimates.
