Vacation in Indonesia in September will be to the liking of those tourists who want to bask under the rays of the warm sun, but at the same time to save money. This is due to the fact that the flow of tourists is reduced, and hoteliers are forced to reduce prices. However, when planning a tour to Indonesia in September, do not forget that the country is preparing for the wet season. Because of this, the air humidity increases, and on the east coast a small amount of precipitation is possible.
