Indonesia Weather & Climate Guide 2026

When to visit Indonesia: real monthly data on temperature, rain, and crowds — not vibes.

Indonesia is a vast archipelago of over 17,000 islands, offering incredible diversity from ancient temples and volcanic landscapes to pristine beaches and vibrant coral reefs. Home to unique cultures, world-class diving, and lush rainforests, it's exceptional territory for adventure seekers and culture enthusiasts alike.

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.
