Indonesia is one of the world’s most diverse travel destinations. With over 17,000 islands, active volcanoes, tropical rainforests, world-class beaches, and rich cultural experiences, it attracts travelers year-round.
However, choosing the right time to visit can dramatically improve your experience.
Unlike destinations with four distinct seasons, Indonesia has two main seasons:
- Dry Season
- Rainy Season
Understanding these seasons helps you enjoy better weather, avoid crowds, and save money.
| Season | Months | Weather | Crowds | Prices |
|---|---|---|---|---|
| Dry Season | May–September | Sunny and dry | High | Higher |
| Shoulder Season | April, October | Mixed weather | Moderate | Moderate |
| Rainy Season | November–March | Frequent rainfall | Low | Lowest |
Average temperatures remain fairly consistent throughout the year.
| Region | Average Temperature |
|---|---|
| Bali | 26°C–31°C |
| Java | 24°C–32°C |
| Lombok | 25°C–31°C |
| Komodo | 25°C–34°C |
