Visiting Indonesia in October — Weather, Raja Ampat & Travel Tips

October is a month of transitions. Bali and Java shift back into wet season — the first rains return after a dry summer and prices drop as many tourists have left. Meanwhile, Raja Ampat opens for its best dive season: October through April brings calm seas, extraordinary visibility, and the chance of seeing whale sharks, manta rays, and wobbegong sharks. The Ubud Writers and Readers Festival is one of Southeast Asia’s most respected literary events.

Wet vs Dry: Regional Overview

Bali and Java: October marks the return of the wet season. Rainfall is modest compared to December–February — early October is often still quite dry, with the transition becoming noticeable mid-to-late month. Mornings remain reliable; afternoon showers return. Temple and inland areas (Ubud, Borobudur) are excellent.

Lombok: Following a similar pattern to Bali but slightly drier. October is still a reasonable beach month, particularly on the sheltered north coast near Senggigi.

Raja Ampat: The highlight of October for Indonesia divers. Seas calm rapidly from October onwards. October is less crowded than November and December, making it a good choice for liveaboard diving. Manta rays are particularly active around Manta Sandy and Cape Kri from October.

Komodo: October is the final reliable month for Komodo before seas build. Some liveaboard operators continue through October but confirm sea conditions before booking.

Events in October

Ubud Writers & Readers Festival (usually mid-late October): One of Southeast Asia’s most important literary festivals. Held across multiple venues in Ubud — the Blanco Museum, Indus Restaurant, ARMA Museum and others. International authors, Indonesian writers, discussions, workshops. Day passes from approximately IDR 200,000 as of 2026; full passes significantly more. Tickets sell out for popular sessions. Book at ubudfestival.com — dates and programme shift annually.

Batik Day (2 October — national cultural day): Batik was inscribed on UNESCO’s Intangible Cultural Heritage list. Indonesian government offices and schools wear traditional batik on this day. Batik markets and exhibitions are held across Yogyakarta and Solo (Surakarta).

Galungan and Kuningan (Balinese Hindu festival — date varies on Pawukon calendar): One of the most important Balinese Hindu holidays. Penjor bamboo poles line every road, and offerings are placed at all household temples. Kuningan follows 10 days later. Dates are set on the Balinese Pawukon calendar — verify at tourism.baliprov.go.id.

Best For / Avoid If

Best for:

• Ubud Writers Festival — high-quality literary programme
• Value travel to Bali — off-peak pricing returns
• Batik shopping in Yogyakarta and Solo

Avoid if:

• You’re set on Bali beach days — south coast swell is returning
• Komodo liveaboards are the priority — conditions are becoming borderline
