Indonesia - When To Go
The best time to visit is between June and October, when it's driest and day temperatures range from 85 to 95 degrees Fahrenheit (29C-35C). November through March is monsoon season, making for dreary travel in some parts. It is advisable to bring a sweater year-round, due to low evening temperatures. Christmas breaks and summer vacation months (especially July and August) can be quite crowded on Bali and in Java.
