Indonesia knows two rainy seasons
1. Between November and March when the northeast monsoon blows from China and the north Pacific
2. Between May and September when the southwest monsoon blows from the Indian Ocean and Australia
The monsoon is a seasonal reversals of winds from southwest in summer to northeast in winter, in principle it is caused by temperature differences between the land and sea. When the sun does its (season-related) work hot air rises from the continent and this draws moisture-laden air in from the (colder) oceans to bring heavy rains.
