Thailand, Bali and Vietnam are three of the most popular international trips from India, and the question people ask most is not which one — it is when. The honest answer is that each has a different best season, and within each country the weather can differ sharply from one coast or region to the next.
Here is how the year breaks down, month by month.
Month-by-month breakdown
January: one of the best months for Southeast Asia
- Thailand: Excellent for beaches, Bangkok and Northern Thailand. January generally brings cooler weather, and both the Andaman and Gulf coasts can offer good beach conditions. If you are looking for the best time to visit Thailand, this is one of the top weather windows.
- Bali: The dry season hasn't started yet, so expect some rain. It suits couples and travellers who don't mind tropical showers.
- Vietnam: A good month for southern Vietnam and the cooler north, although conditions vary considerably by region.
February: beaches and pleasant weather
Thailand continues to be a strong choice, with comfortable weather and good conditions for beach holidays. Bali can still see rain, while Vietnam offers pleasant options across its regions.
March: great for Vietnam and Thailand
March is one of the more versatile months. Vietnam's central regions begin to get sunnier while Thailand moves towards its hotter season — which is why so many people planning the best time to visit Vietnam end up in these spring months. Bali is approaching its dry season, but the weather can still be unpredictable.
April: Bali starts looking better
April is when Bali's dry season begins, making it a better time for beaches, sightseeing and outdoor activities; many travellers consider it the start of the best time to visit Bali. Thailand becomes hot, with Songkran bringing a major cultural celebration in mid-April. Vietnam remains a strong option, particularly central Vietnam.
May: the shoulder-season sweet spot
May can be a smart month if you want to avoid peak-season crowds. Bali is entering its dry period, Thailand is getting wetter in many areas, and Vietnam still offers good regional options.
June: choose your coast carefully
This is where Southeast Asia's weather gets interesting. Bali is firmly in its dry season and excellent for beaches and outdoor experiences. Thailand can be rainy in many areas, but the Gulf side can still work for island trips. Vietnam's central coast is a strong choice for a beach holiday in June.
July: Bali and central Vietnam
Bali remains a strong choice for a classic summer holiday. Central Vietnam, including Da Nang and Nha Trang, is particularly attractive for beaches in July. Thailand is possible, but rainfall varies by region.
August: Bali still shines
Bali continues in its dry season. In Vietnam, Sapa's rice terraces begin turning gold towards late August and into September, one of the most photographed sights in the north. Thailand is generally wetter, so choose your islands carefully.
September: Thailand's Gulf coast or northern Vietnam
September is a tricky month. The southwest monsoon is still working Thailand's Andaman coast, so the Gulf of Thailand is usually the better bet — Koh Samui and Koh Tao make more sense than Phuket or Krabi. Hanoi and northern Vietnam can be attractive in September, while Bali is nearing the end of its dry season.
October: the transition month
October marks the turn towards better weather in Thailand, as the rainy season begins to retreat. Bali is approaching its wetter period, while northern Vietnam offers excellent nature experiences such as Pù Luông at harvest time.
November: Thailand takes the lead
November is when Thailand starts its popular travel season. Vietnam also has excellent options, particularly in the north, such as Hà Giang. Bali begins moving into its wet season, although showers rarely mean the whole day is lost.
December: beach season returns
Thailand is a strong December choice, especially for beaches and island holidays. Vietnam's Phu Quoc comes into its dry season around now, which makes it a particularly good tropical escape. Bali is in its wet season, so expect more humidity and rainfall.
So, what's the best month overall?
If you are choosing primarily on weather:
- January–February: Thailand and Vietnam
- March–April: Vietnam and Thailand
- May–June: Bali and central Vietnam
- July–August: Bali and central Vietnam
- September: Thailand's Gulf coast and northern Vietnam
- October–November: Thailand and Vietnam
- December: Thailand and southern Vietnam
For Bali specifically, April to October is generally the drier period.
For Thailand, look at the region and the coast, not just a country-wide forecast. The Gulf and Andaman coasts can have very different conditions in the same month.
Vietnam is even more regional: the north, centre and south can have very different weather at the same time.
Frequently asked questions
1. Which is the best month to visit Southeast Asia from India?
There isn't one universal month. November to February is generally a strong window for Thailand and parts of Vietnam, while April to October works particularly well for Bali.
2. Which is better for a summer trip: Bali or Thailand?
For a June–August trip, Bali and central Vietnam generally offer more reliable beach conditions than many parts of Thailand.
3. Is September a bad month for Southeast Asia?
Not at all — you just need to choose the destination carefully. Thailand's Gulf coast can be a better option than its Andaman coast, and northern Vietnam can also work well.
4. Can I visit Thailand, Bali and Vietnam on one trip?
Yes, but don't try to cover all three in a short holiday. A 10–14 day trip covering two countries makes for a far more comfortable itinerary. That one change makes a Southeast Asia holiday much easier to plan, and a lot more enjoyable.
