Travelling in Southeast Asia’s Monsoon Season: What You Need to Know
When most people picture Southeast Asia, they imagine warm sunshine, palm-fringed beaches and sunset cocktails. But if you’re planning a trip between May and October, you’ll likely encounter the monsoon season—a time of heavy rains, humid air and dramatic tropical storms.
Don’t let that put you off. The monsoon doesn’t mean constant rain. In most destinations, it’s more like short, powerful downpours, often in the late afternoon or evening, leaving plenty of time to explore during the day. Plus, you’ll find smaller crowds, lower prices and stunning green landscapes at this time of year.
What to Expect During Monsoon Season
- Rain usually comes in bursts, not all day.
- The air is more humid, and temperatures remain warm.
- Some islands or rural areas may experience flooding or transport delays.
The key is to be prepared and flexible.
Tips for Travelling During Monsoon Season
Pack the Right Gear
- A lightweight rain jacket or poncho.
- Dry bags or waterproof covers for your phone, passport and camera.
- Quick-dry clothing and footwear.
Keep Plans Flexible
- Do outdoor activities earlier in the day when it’s usually clearer.
- Have indoor alternatives ready—cafes, markets, museums.
- Allow extra time in case flights or ferries are delayed.
Stay Connected with an eSIM
Weather changes quickly, and reliable mobile data makes a big difference. You can:
- Check real-time weather updates.
- Rebook tours or transport on the go.
- Stay in touch with guides, drivers and hotels.
We recommend setting up your eSIM before you travel, so you’re online the moment you land. Two great options are:
- Asia Explorer eSIM – covers 10 destinations across Asia, ideal if you’re visiting multiple countries.
- Southeast Asia eSIM – tailored for travellers exploring Southeast Asia specifically.
Pick the Right Destinations
Not everywhere is equally wet:
- Thailand: The Gulf coast (Koh Samui, Koh Phangan) stays drier than the Andaman coast.
- Vietnam: Rain patterns vary—check conditions for north and south.
- Indonesia: Eastern islands (like Flores) often see less rain than Bali or Sumatra.
Why Travel During Monsoon Season?
- Better value: Hotels and tours are usually cheaper.
- Beautiful scenery: Lush rice paddies, waterfalls and rainforests.
- Less crowded: A more relaxed travel experience.
