Climate Overview
Indonesia has a tropical climate with consistently high temperatures (25-33°C/77-91°F) year-round and high humidity. The country is divided into two main seasons: dry (April-October) and wet (November-March), though patterns vary across the vast archipelago — Bali's dry season coincides with Java's, while Sulawesi and Maluku have different patterns. Altitude significantly affects temperature: highland areas like Ubud, Dieng Plateau, and Toraja are refreshingly cooler.
