Indonesia has a tropical climate, with variations throughout the country - it's generally cooler inland and at higher elevations compared to the coastline and lowlands.
The northeastern monsoon brings cool, dry weather from June to September, while the southwestern monsoon brings heavy rains from December to March. Average annual temperature stands at 86°F (30°C).
Travelers are advised to visit between April and October, when the weather is not too hot and not too wet either. The southwestern monsoon often wipes out many roads, making travel difficult during this time.
