Dreaming of Vietnam but unsure when to go? With its misty northern peaks, lantern-lit towns, and sun-drenched southern shores, this is a country that feels different in every season – and that’s exactly what makes it so captivating.

Stretching over 1,600 kilometers and spanning multiple climates, Vietnam offers something special year-round: golden rice fields in autumn, balmy beach escapes in winter, vibrant festivals in spring, and lush green landscapes in summer. Our month-by-month weather guide will help you uncover the best time to visit, tailored to your interests, so you can experience Vietnam in its most breathtaking light.

Overview of weather in Vietnam

Vietnam’s climate is as varied as its landscapes. Thanks to the country’s long, slender shape, you will encounter three distinct weather zones as you move from north to south — each offering its own rhythm of seasons and surprises.

North Vietnam (Hanoi, Halong Bay, Sapa, Ninh Binh):

A place of four true seasons. Winters (Dec–Feb) can be misty and cold, while summers (May–Aug) are hot and humid. Spring (Mar–Apr) and autumn (Sep–Nov) bring the best balance, with crisp air, clear skies, and landscapes in bloom.

Central Vietnam (Hue, Da Nang, Hoi An, Nha Trang, Phan Thiet):

Known for its sun-drenched summers (Feb–Aug) and a rainy season from Sep to Jan. Occasional storms may roll in, especially around October, but even rainy days have a certain poetic charm, especially in Hue’s imperial gardens or Hoi An’s lantern-lit streets.

Southern Vietnam (Saigon, Mekong Delta, Phu Quoc, Con Dao):

Think tropical all year round, with two main seasons: dry (Nov–Apr) and wet (May–Oct). Even in the rainy season, showers tend to be short and refreshing, clearing the air just in time for a sunset river cruise or a street food stroll.

The beauty of Vietnam’s varied climate is this: while one region may be drenched in rain, another is basking in sunshine. With smart planning, there is always somewhere beautiful to be, no matter the month.

So, When Should You Visit Vietnam?

There is no single “best” time – it all depends on the kind of journey you are dreaming of. Here is how to plan your trip based on your interests:

☀️ If you love beaches and sunshine:

South & Phu Quoc: Best from November to April with warm, dry, sunny days.

Central Coast (Hoi An, Da Nang, Nha Trang): Best from March to August, when the seas are calm and skies are clear.

🥾 If you enjoy trekking or cultural experiences:

The northern highlands, like Sapa and Ha Giang, shine from March to May and September to November, with blooming spring terraces or golden autumn rice fields. For a cultural twist, January and February bring Tet and lively local festivals, though it can be colder and busier.

💸 If you are traveling on a budget: The low season – particularly May, June, and September – brings fewer crowds and better rates. You might catch some rain, but also lush landscapes and more intimate local encounters.

From misty mountain trails to sun-kissed shores, Vietnam offers something different in every season. No matter when you go, there is always a part of Vietnam that shines.
