The Best Time to Visit Southeast Asia, Country by Country

Southeast Asia does not have a single season. The rains reach each coast at a different time, so a good month for one beach can be a poor month for another. The good news is that there is nearly always somewhere sunny, which means you can choose your destination by month instead of forcing your destination into a fixed set of dates. This guide gives general patterns for the most popular countries. Weather varies from year to year and from one coast to the next, so treat these as a starting point and check a current forecast before you book flights or non-refundable rooms.

Thailand

The Andaman coast, which includes Phuket and Krabi, is at its best from roughly November to April, with calmer seas and plenty of sunshine. The Gulf islands, such as Koh Samui, follow a different pattern and are often pleasant during the middle of the year, when the western coast is wetter. Bangkok is hot all year, with the most comfortable weather from about November to February. The north, around Chiang Mai, is cooler and drier in the cool season, but the hills can be hazy at the end of the dry season. If you want to combine city and beach, pair Bangkok with whichever coast is calm that month.

Vietnam

North, central and south Vietnam each have their own rhythm, which is why a single trip can include very different weather. Hanoi is lovely in autumn and spring and can be cool and grey in winter, with warm, humid summers. Da Nang and Hoi An are at their best from about February to May, with storms more likely in autumn and some flooding possible in the old town. Ho Chi Minh City is driest from December to April and has afternoon showers in the wetter months, usually short and heavy. On a north-to-south trip, spring and autumn are often the most balanced compromise.

Indonesia and Bali

Bali's dry season runs from about April to October. July and August are the busiest and most expensive months, so consider the shoulder months of May, June and September for good weather with lower prices and thinner crowds. The wetter season brings green landscapes, dramatic skies and quieter beaches, though some days will be lost to rain. Beyond Bali, Indonesia is huge and its weather is not uniform, so check the season for each island separately. Surf spots, diving areas and volcano hikes all have their own best months, and local guides are usually honest about what to expect.

Malaysia and Singapore

Both are warm and humid all year, with showers at almost any time, so the question is less about avoiding rain and more about managing it. Singapore is often drier in the early months of the year, though a sudden downpour is always possible. In Malaysia, the west coast, including Penang and Langkawi, tends to be drier from about December to February, while the east coast has a heavy rainy season at the end of the year, and some island operators close for a few months. Kuala Lumpur sees afternoon thunderstorms in many months, so plan outdoor sights for the morning.

Cambodia, Laos and the Philippines

Cambodia and Laos have a clear dry season, generally cooler from about November to February, which is the most comfortable time for temple visits. The hottest weeks come before the rains, when midday walking becomes hard work. The Philippines is spread over a vast area, with the drier months generally falling in the first half of the year, and the typhoon season concentrated later in the year. If you plan island hopping there, keep your schedule flexible, because boats can be cancelled in rough weather. A rest day built into the itinerary protects the rest of your trip.

Do not fear the green season

Lower prices, fewer crowds and short afternoon showers can be an excellent trade. Many resorts offer their best rates in the wetter months, and landscapes look their greenest. Pick a hotel with a good indoor space, such as a spa, a restaurant or a games room, and plan outdoor activities for the morning, when skies are often clearer. Pack a light rain jacket, quick-dry clothes and a waterproof bag for your phone. The main risks are rough seas and cancelled boat trips, so avoid tight connections and leave a spare day before any international flight.

Plan around events too

Local holidays and festivals can fill hotels and raise prices quickly. Lunar New Year, Songkran in April and major national holidays are exciting to experience but require early booking, and transport can be fully booked well ahead. Some events also close businesses for several days. Check the calendar for the country you plan to visit before you choose dates, and decide whether you want to join the celebration or avoid the crowds. Either choice is fine, as long as you make it on purpose and book accordingly.
