Does It Rain All Day During the Rainy Season?

Don't worry. Rainfall during the monsoon is not continuous. Certain countries can have consecutive days of sunshine with little to no rainfall.

While it may rain very frequently during the rainy season, it rarely rains all day. Mornings are usually bright and clear with a short (but torrential) shower in the afternoon.

So, you can plan your schedule around these downpours and make the most out of your time in Southeast Asia.

What Is a Monsoon?

You may be confused about the difference between the rainy season and the monsoon season.

Monsoon season is when the winds bring humidity from the Indian Ocean to the Southeast Asian subcontinent. The seasonal winds commonly bring heavy rains and thunderstorms, which constitutes the rainy season.

What to Expect in Southeast Asia During the Monsoon Season?

Most countries in Southeast Asia are affected by monsoons including Thailand, Laos, Vietnam, Cambodia, Myanmar, Philippines, and Malaysia. Here's a country-by-country guide on what to expect during the monsoon season.


  • Monsoon season: Thailand's monsoon season typically runs from June to October. The most rainfall in Thailand occurs from August to October. In Bangkok, the rainy season starts in late June or July, in Chiang Mai it's from May to October, in Koh Samui it's October to December, and in Phuket it's May to October.
  • What to expect: It rains very frequently (almost every day), but typically in the late afternoon or early evening. Some of the islands may be closed due to rip currents and typhoons. You will see fewer travelers and can save as much as 50% on the cool-season hotel prices.
  • Best destinations to visit: Samui, Koh Pha Ngan, or Koh Tao. They get less rain than the rest of Thailand during the monsoon season.


  • Monsoon season: In the north, around Hanoi and Ha Long Bay, it starts in May and ends in October, with the wettest months of the year being July and August. In central Vietnam (Hoi An, Hue, and Danang), rainfall increases in October and November. In the south, around Ho Chi Minh City, the monsoon season runs from May till November.
  • What to expect: The rainy season in Vietnam is not quite as severe as it is in other Southeast Asian countries. Rainstorms rarely last more than one hour and often occur at night. Floods are rarely seen. The tour boats in Ha Long Bay may get canceled sometimes.
  • Best destinations to visit: In October, November, and December, places in the north such as Hanoi and Sapa can be great destinations. From January through July, the coastal stretch from Hue down to Nha Trang are wonderful spots. From November through to February, Saigon and the Mekong Delta are perfect to holiday in. See more about the Vietnam weather.


  • Monsoon season: The wet season in Cambodia runs from June to November, with particularly heavy rains in September and October.
  • What to expect: It rains just for a couple of hours during the day in the monsoon season. The roads will be dirty. The rainy season is known as the green season, when you can see the countryside erupt with beauty with lush rice paddy fields and flourishing tropical jungles. There are fewer tourists and prices are lower.
  • Best destinations to visit: Any place, as long as you plan well. See more about the best time to visit Cambodia

  • Monsoon season: The rainy season lasts from June to October, with typhoons being likely from September through October.

Tips for Traveling in the Rainy Season in Southeast Asia

1. Be ready for travel delays

Planes and ferries are more likely to be cancelled. Before you travel, verify that your comprehensive travel insurance plan has the coverage you may need for possible delays and interruptions.

2. Arrange a relaxed schedule and flexible itinerary

As your itinerary might be affected by heavy rains and cancellations of transportation, you should allow plenty of waiting time in your travel itinerary.

3. Keep an eye on the local weather forecast

To ensure your safety, check the local weather, especially if you are going to hilly regions. There may be mudslides and landslides during heavy rainfall.

4. Try alternative indoor activities

When you plan your travel, add some indoor activities to your itinerary, such as a cooking class, an arts and craft workshop, a Thai massage, or a yoga class. This way, you will still have ample things to do when it rains.

5. Pack waterproof and quick-drying items

The weather in the monsoon season can be hot and humid, so wear light and loose clothing to keep you cool. Here are some things you should consider packing: 

  • A waterproof jacket, an umbrella, or a raincoat
  • A waterproof bag
  • Quick-dry clothing
  • Flip flops or plastic sandals
  • Some medicines and insect repellants
