Visiting Indonesia in January — Weather, Events & Travel Tips
January is the heart of the wet season across Bali and Java, which keeps crowds and prices lower than the peak months of July and August. For divers and snorkellers, Raja Ampat is at its best right now. Expect afternoon downpours rather than all-day rain — mornings are often clear, and the green season has its own appeal.

Wet vs Dry: Regional Overview
Wet season regions (Oct–Apr): Bali, Java (Jakarta, Yogyakarta), Lombok, Flores. Rain falls mainly in the afternoon and evening — mornings are frequently sunny. Flooding is rare outside of Jakarta’s urban drainage problem areas.
Dry season region: Raja Ampat and much of eastern Indonesia are in their best window. October through April is when the seas are calm and underwater visibility reaches 20–30 metres.
Sulawesi: North Sulawesi (Manado, Bunaken) is transitioning out of its better season. Expect increasing rain through January. South Sulawesi (Makassar, Tana Toraja) mirrors Java’s wet season.
Events in January
New Year Celebrations (1 Jan, nationwide): Fireworks are large in Jakarta (Monas / National Monument area) and Bali (Seminyak and Kuta beaches). Free to attend but expect heavy crowds on the streets. Book accommodation months in advance for New Year’s Eve.
Ramadan preparation: Ramadan dates shift annually — in some years it may begin in late January or February. Check the Indonesian government’s official calendar at indonesia.go.id for the current year’s dates. During Ramadan, restaurant hours change and alcohol availability is reduced in some areas.
Quiet Shoulder Period (mid-Jan onwards): After New Year, Bali enters one of its quietest stretches. Rates at most hotels drop noticeably from approximately mid-January.

Frequently Asked Questions
- What is the weather like in Bali in January?
- January is the heart of the wet season in Bali. Average rainfall exceeds 300mm for the month, humidity is around 85%, and afternoon and evening downpours are frequent. Mornings are often sunny and clear. It is not the best month for beach travel on the south coast, but Ubud and cultural sites remain fully accessible.
- Is January good for Raja Ampat diving?
- January is one of the best months for Raja Ampat. The archipelago is in its calm season (October through April), with underwater visibility reaching 20–30 metres. Mantas at Manta Sandy are reliable, and the full reef system is accessible. Book resort or liveaboard accommodation at least three months ahead.
- Is Indonesia cheap to visit in January?
- After the New Year peak subsides (roughly mid-January onward), Bali and Lombok enter their quietest and cheapest stretch of the year. Guesthouses in Ubud from approximately USD 45/night and boutique resorts from approximately USD 150/night represent good value relative to the same properties in peak season.
- What can you do in Bali during wet season in January?
- Ubud is the best base in wet season — the rice terrace scenery is lush and green, cultural attractions (Monkey Forest, dance performances, cooking classes, temples) operate year-round regardless of rain, and the afternoon showers rarely last more than an hour or two.
- Are volcano treks possible in Bali in January?
- Bromo and Ijen in Java remain accessible in January, though conditions are less predictable than dry season. Rinjani on Lombok is formally closed to trekkers during peak wet months (December through February). Check current conditions with operators before booking.
