Together, these countries cover about 4.5 million square kilometers, which is 3% of the world’s land area. Over 680 million people live in the region.
Tourism is a big part of the economy here. Most visitors come to Thailand, Malaysia, and Singapore.
Southeast Asia is divided into two main parts:

Monsoon Season in Southeast Asia – What Does It Feel Like?
We’ve been living in Southeast Asia since 2019 and have experienced monsoon seasons in Thailand, Malaysia, and Indonesia. In my experience, the rainy season is unpredictable. Some years, southern Thailand had serious floods, with rain pouring down from morning to night. Other years, it only rained in the afternoons, and even then, it was just short showers.
In Bali, the monsoon season felt quite mild. Rain usually came in short bursts during the afternoon. In Malaysia, we were so lucky one October that it barely rained at all—even the locals were surprised!
So, would I recommend traveling to Southeast Asia during the rainy season? Well, on the one hand, it’s great because prices drop, and there are fewer tourists. On the other hand, it can rain for days on end, leaving you hopping from one restaurant to another just to stay dry. That can get frustrating.
If you can, I’d suggest avoiding the rainy season. Instead, aim for the shoulder season—the time when one season transitions into the next. Prices are already better, and the weather isn’t as wet or unpredictable. It’s the perfect middle ground!
Seasonal Travel Tips: Festivals and Cultural Highlights
Southeast Asia’s festivals offer unique cultural experiences, but they can also impact travel plans. Here are some highlights to consider for 2025:
- Tết (Vietnam): The Vietnamese Lunar New Year, falling on February 9, 2025, features colorful parades, lion dances, and family celebrations. Expect closures of shops and restaurants for up to a week.
- Songkran (Thailand): Held April 13-15, 2025, this Thai New Year festival involves playful water fights across the country, from Bangkok to Chiang Mai. It’s a lively time but also very crowded, especially in popular tourist spots. Book accommodations early as hotels fill up quickly.
