The driest period in Indonesia falls between April and October, with July and August the peak season for beach resorts in Bali, Lombok and elsewhere. At other times of year, you can expect more rain, although even in the dry season, the jungle regions of Sumatra and Kalimantan receive near daily downpours, which, however, quickly pass. Humidity levels vary greatly. While islands such as Komodo and Rinca are surprisingly arid, rainforest areas remain sticky year round. The only properly cold places in Indonesia are the very tops of the high peaks, where temperatures may plunge to near freezing before sunrise.
