Indonesia is a year-round destination — but when you go shapes what your trip looks like. Straddling the equator across more than 17,000 islands, the country has no real winter or summer: it has a dry season (roughly April to October) and a wet season (roughly November to March), and the difference between them matters more in some regions than others.
This month-by-month guide to the best time to visit Indonesia in 2026 breaks down the seasons, highlights what is good each month, and flags the best windows for Bali, Komodo, Raja Ampat, surfing, and festivals — so you can plan with confidence.
The dry season (April–October) means blue skies and calm seas across most of Indonesia.
Indonesia's Two Seasons: Dry vs Wet
Dry Season (April to October)
The dry season is the default best time to visit Indonesia for most travelers. Skies are blue, rain is rare, seas are calm, and boat crossings to places like Nusa Penida, the Gilis, and Komodo run reliably. Visibility for diving and snorkeling is at its best. The trade-off: it is peak season — July, August, and the Christmas–New Year stretch (technically wet season, but many come anyway) bring the biggest crowds and the highest prices.
Wet Season (November to March)
The wet season means afternoon downpours, higher humidity, and rougher seas. Fast boats and inter-island crossings get cancelled more often. But it is also quieter and cheaper, the rice terraces and waterfalls are at their lushest, and surfing on Bali's west coast is at its peak. Rain rarely lasts all day — mornings are often fine, with storms rolling in during the afternoon.
Month-by-Month: What Is Good When
January
Peak wet season. Expect heavy afternoon rain and rough seas in most regions. Good for: surfing Bali's west coast (Uluwatu, Canggu), cheap prices, and quiet temples. Bad for: Komodo boats and Raja Ampat crossings.
February
Still wet, but the rain starts easing late in the month. Chinese New Year brings festive energy in cities with large Chinese-Indonesian communities. Good for: low prices and empty beaches between showers.
March
The shoulder month — rain fades, seas calm down, and prices are still low. Nyepi (Bali's Day of Silence) usually falls in March: the island shuts down completely for 24 hours, a unique cultural experience if you plan around it. One of the best-value months to visit.
April
The dry season begins. Skies clear, seas calm, and the crowds have not arrived yet. Excellent for diving in Komodo and Nusa Penida (manta ray season peaks around now). One of the overall best months.
May
Prime dry-season weather with moderate crowds. Great for island hopping — the Gilis, Nusa Penida, and Lombok are all in top form. Waisak (Buddha's birthday) is celebrated at Borobudur with a spectacular lantern release.
June
Peak conditions begin: blue skies, calm seas, great visibility. Prices and crowds start climbing toward the July–August peak. Book accommodation ahead if you are visiting popular areas.
The wet season brings lush, vibrant landscapes — but also daily downpours and rougher seas.
July
The busiest month of the year — school holidays in Europe and Australia collide with perfect weather. Bali, the Gilis, and Komodo are packed; book boats, hotels, and Komodo cruises well ahead. The Bali Kite Festival fills the skies over Sanur.
August
Still peak season and still glorious weather. Independence Day (August 17) brings colorful celebrations and games across the country. Prices remain high until the very end of the month.
September
Crowds thin out but the weather holds — arguably the sweet spot of the year: dry-season conditions at shoulder-season prices. Excellent for Komodo, diving, and climbing volcanoes like Rinjani and Bromo.
October
The transition month. The first rains arrive late in the month, but early October still feels like dry season. This is the start of the prime window for Raja Ampat (October–April), when seas calm in the far east.
November
Wet season proper begins. Daily rain, rough seas, and cancelled boat trips become common. The upside: the lowest prices of the year and the lushest landscapes. Surf season fires up on Bali's west coast.
December
Wet — but the Christmas–New Year holidays are one of the busiest periods in Bali regardless, with big crowds and peak prices. Expect rain between the celebrations; pack accordingly.
Best Months for the Big Destinations
- Bali: April–October for beaches and boats; November–March for surfing the west coast and budget prices.
- Komodo National Park: April–October, with September offering the best mix of conditions and fewer crowds. Liveaboard boats run year-round but schedules thin out in January–February.
- Raja Ampat: October–April — the opposite of Bali. Calm seas and the best diving visibility fall in Indonesia's wet season. July–September brings rough water here.
- Java (Borobudur, Bromo, Ijen): April–October for sunrise viewpoints and volcano climbs; the wet season makes trails slippery and views cloudy.
- Lombok and the Gilis: April–October. Wet-season seas cancel the fast boats from Bali.
Surf Season in Indonesia
Indonesia has two surf seasons. April to October, the southeast trade winds groom the reefs of Bali's west coast (Uluwatu, Padang Padang, Canggu) and fire up the legendary breaks of the Mentawai Islands, Nias, and G-Land in East Java. November to March, the winds flip and Bali's east coast (Nusa Dua, Keramas, Sanur) lights up instead. Beginners can learn year-round at forgiving beach breaks like Batu Bolong in Canggu.
Raja Ampat has its own seasons: October–April is the prime window for diving and calm seas.
Festivals Worth Timing Your Trip For
- Nyepi (March): Bali's Day of Silence — the whole island goes quiet for 24 hours. A once-in-a-lifetime cultural experience.
- Waisak (May): Thousands of lanterns released at Borobudur at dawn.
- Bali Kite Festival (July–August): Giant traditional kites flown from Sanur beach.
- Galungan and Kuningan: Bali's most important religious festivals, celebrated every 210 days — the island is decorated with towering bamboo penjor poles.
- Toraja funeral ceremonies (July–September): In Sulawesi, elaborate multi-day funeral rituals are held in the dry season and visitors are welcome.
Practical Tips for Planning Around the Weather
- Book boats with buffer days. In the wet season, leave a spare day before any international flight if you are island hopping.
- Shoulder seasons win. April–June and September–October give you dry-season weather without peak-season prices.
- Pack for both. Even in the dry season, mountain areas (Bromo, Rinjani, Dieng) are cold at dawn — bring a warm layer. In the wet season, a light rain jacket and waterproof bag go a long way.
- Volcano sunrises need dry air. For Bromo, Ijen, and Rinjani, the April–October window dramatically improves your chances of a clear sunrise.
- Check regional differences. Indonesia is huge — when Bali is wet, Raja Ampat and parts of Maluku are at their best, and vice versa.

FAQ
What is the absolute best month to visit Indonesia?
September. Dry-season weather across Bali, Java, Komodo, and the Gilis, with the peak crowds gone and prices easing. April–June is a close second for the same reasons.
Can you visit Indonesia in the rainy season?
Yes — it is cheaper, quieter, and the landscapes are at their greenest. Just plan around afternoon rain, expect some cancelled boat trips, and avoid scheduling tight connections after island crossings.
When is the best time to visit Bali specifically?
April to October for beaches, diving, and island hopping. November to March if you are a surfer chasing the west coast swell or a budget traveler happy to trade some rain for lower prices.
When should I go to Raja Ampat?
October to April — the opposite season from Bali. Seas are calmest and diving visibility is best during Indonesia's wet season. Avoid July–September, when the water gets rough.
Is December a bad time to visit Indonesia?
It is wet, but it is also one of the busiest periods in Bali because of the holidays. Expect rain, big crowds, and peak prices. If you must come then, book everything early and pack rain gear.
Indonesia rewards travelers who match their timing to their plans: dry season for boats and beaches, shoulder months for value, and the far east's own rhythm for Raja Ampat. When are you planning to go? Share your dates in the comments and we will help you fine-tune!
