The Best Time to Visit Indonesia
Curated by Our Guild Explorers · Updated August 2026
Short answer: the dry season, roughly April to October, is the best time for Bali, Java, Lombok and Komodo, and May, September and early October give you that weather without peak crowds or peak prices. The wet season from November to March is hot, green and much cheaper, with rain that usually falls in short afternoon bursts. One region runs the other way entirely: Raja Ampat in the far east is at its best from October to April.
Indonesia straddles the equator, so it does not really have four seasons — it has a monsoon cycle. Temperatures barely move all year: the coastal lowlands sit at around 28 to 32°C (82 to 90°F) by day, with high humidity, and only altitude changes that. What moves is the rain, and where in this vast archipelago it happens to be falling. The country is more than 3,000 miles across and spans three time zones, so “the best time to visit Indonesia” genuinely depends on which islands you have in mind.
The Seasons at a Glance
Indonesia’s ‘seasons’ are monsoon phases — here is the quick read for the regions most travellers visit.
Dry season — April to October
The southeast monsoon brings the country’s best weather to Bali, Java, Lombok and Komodo: sunny days, lower humidity, calmer seas and reliable boat crossings. June to September are the driest and the busiest; April, May, September and October give you nearly the same weather without the peak-season prices.

The northwest monsoon is hot and humid, with rain that usually arrives as an intense afternoon or evening downpour and then clears — not the all-day drizzle many travellers expect. Mornings are often bright, the rice terraces are at their greenest, temples are uncrowded, and rates fall sharply. February is typically the quietest and cheapest month of the year.
Find Green-Season Hotels ›Peak crowds — July, August and late December
Northern-hemisphere summer and the Christmas and New Year fortnight bring the biggest crowds and the highest prices of the year, particularly in southern Bali and on the Gili Islands. Australian school holidays add a further surge in late June, July and around Easter. If you must travel then, book three to six months ahead.
The eastern exception — Raja Ampat, October to April
Raja Ampat, in the far east, runs on the opposite calendar: it is at its best from October to April, with December to March the peak for calm water, superb visibility and manta aggregations, while many liveaboards suspend operations in July and August. This matters when planning — the best months for Bali are the worst for Raja Ampat, so combining the two in one trip means compromising on one of them.
Month by Month
The concise version for a trip built around Bali and Java — weather, crowds, and what each month does best.
January
The wettest month of the year, with heavy afternoon and evening downpours, high humidity and choppy seas. Crowds thin sharply after the first week and rates fall — good value if you accept the rain and keep some indoor and cultural plans in reserve.
February
Peak wet season, and typically the quietest and cheapest month on the calendar. Expect rain most days and rough crossings to the Gili Islands, but also brilliantly green rice fields, empty temples and the lowest hotel prices of the year.
March
The monsoon eases through the month, with drier, brighter spells by late March, while crowds and prices stay low. Note Nyepi, Bali’s Day of Silence, which usually falls in March and closes the whole island for 24 hours — airport included. Check the date: it is either a remarkable experience or a serious inconvenience.
April
The dry season begins and conditions improve markedly — a genuinely excellent shoulder month, with good weather and none of the July prices. Easter brings a short Australian-holiday surge to Bali, so check the dates before booking.
May
One of the best months of the year: reliably dry, comfortable humidity, clear water and strong visibility, and still shoulder-season pricing. Ideal for combining Bali with Bromo and Borobudur in one unhurried trip.
June
Dry, sunny and pleasant, with the most agreeable humidity of the year. Crowds and rates build steadily through the month as the peak season opens, so book ahead for late June, particularly in southern Bali.
July
Peak season: the driest, sunniest weather but the biggest crowds and the highest prices of the year. Southern Bali and the Gilis get genuinely busy, and the popular hotels and Bromo sunrise trips sell out well in advance.
August
Still peak — excellent dry weather, but maximum crowds, premium rates and noticeably stronger winds and bigger swells on the southern beaches. Indonesian Independence Day on 17 August brings parades and local festivity everywhere.
September
Arguably the best month of the year. Dry-season weather holds, the crowds fall away after the first week, prices soften, and the seas are calm and clear for island-hopping. If you can choose freely, choose September.
October
A fine shoulder month with mostly dry, warm days and the first occasional showers late on. Quiet and good value — and the start of the best season for Raja Ampat, if you are heading east.
November
The northwest monsoon arrives and showers become regular, though usually in short afternoon bursts rather than all day. Low crowds and low prices make it one of the better-value months before the Christmas surge.
December
Wet and humid, and a month of two halves: the first two or three weeks are quiet and inexpensive, then prices and crowds spike hard from around the 20th for Christmas and New Year. Book the holiday fortnight months in advance, or travel early in the month and save considerably.
The Cheapest Time to Go
If price is the deciding factor, the green season is your friend — and the rain is rarely as bad as it sounds.
Green season — November to March
Hotel rates and airfares fall sharply once the northwest monsoon sets in, and the rain typically comes as a heavy afternoon burst rather than a wasted day. February is usually the cheapest month of all, with late January and early March close behind. Bring a light rain jacket, plan the sightseeing for the morning, and your money will go a very long way.

The first three weeks of December, before the Christmas rush begins around the 20th, are among the best-kept secrets in the Indonesian calendar — quiet temples, soft prices and weather no worse than November. Early November works the same way, just after the dry season ends and before anyone starts thinking about the holidays.
Find Shoulder-Season Hotels ›Heat, Rain & Crowds
Three practical things worth knowing before you fix your dates.
The heat barely changes — the rain does
Coastal Indonesia is warm and humid every month of the year, so do not plan around temperature — plan around rain and crowds. Altitude is the one real relief: Ubud at around 600 feet is noticeably cooler than the coast, the highlands of Java cooler still, and the rim of the Bromo caldera can drop close to freezing before dawn. Take a warm layer if a volcano sunrise is on your list.
Volcanic ash delays flights more often than eruptions endanger travellers
Indonesia has around 130 active volcanoes and eruptions are routine and closely monitored. For visitors the usual consequence is not danger but disruption: ash can close airports in Bali and eastern Indonesia for a day or two at a time. Leave a spare day before any international departure, prefer flexible fares, and check with your airline the day before you fly.
Book far ahead for July, August and Christmas
The peak weeks fill early, particularly in southern Bali, Ubud and on the Gili Islands, and the best-value rooms go first. Australian school holidays add surges in late June, July and around Easter that catch many American visitors by surprise. If your dates are fixed in the peak season, book three to six months out.
Best Time by Region
The country is too big for one calendar. Here is how the main regions differ.
Bali & Java
The classic pattern: dry from April to October, wet from November to March, with June to September the driest and most reliable. This is the calendar most travellers are planning around, and it covers Bali, Ubud, Yogyakarta and Borobudur, Jakarta and Mount Bromo.
Find Bali & Java Hotels ›Lombok & the Gili Islands
Lombok and the Gilis track Bali closely, with May to September the best window and the calmest fast-boat crossings. January and February bring the roughest seas, and crossings are occasionally cancelled — something worth knowing if the boat ride is a concern.
Find Lombok Hotels ›Sumatra
Sumatra is wetter overall and shifted from the national pattern: the north around Lake Toba and Bukit Lawang is drenched around October to December, and May to September is the better bet. It is rainforest, though, so expect rain in any month and pack accordingly.
Find Sumatra Hotels ›Sulawesi & Komodo
Northern Sulawesi around Manado and Bunaken is best from March to October, and the south follows the usual April-to-October dry pattern. Komodo, reached from Labuan Bajo, is at its best from April to October; the seas are roughest in January and February, when some boats stop running.
Find Komodo Hotels ›Raja Ampat — the opposite calendar
The most important exception in Indonesian travel planning. Raja Ampat is at its best from October to April, with December to March the peak for calm seas, twenty to thirty metres of visibility and manta aggregations. May to September is its rough season and many liveaboards suspend operations in July and August — precisely when Bali is at its finest.

Frequently Asked Questions
What is the best time to visit Indonesia?
For Bali, Java, Lombok and Komodo, the dry season from April to October is the best window, with June to September the sunniest. If you want that weather without peak crowds and prices, aim for May, September or early October. Raja Ampat, in the far east, is the exception and runs from October to April.
What is the cheapest time to visit Indonesia?
February is usually the cheapest month, followed by late January, early March and early November. These are wet-season months, but the rain generally comes as short heavy downpours rather than all-day grey, and hotel rates can be half what they are in July.
Does it rain all day in the wet season?
Usually not. Outside the very wettest weeks, rain arrives as an intense afternoon or evening downpour that clears within an hour or two, and mornings are often bright and clear. Plan sightseeing for the morning, keep the afternoon flexible, and the wet season is far more pleasant than its name suggests.
What is Nyepi, and will it affect my trip?
Nyepi is Bali’s Hindu Day of Silence, usually in March. For 24 hours the entire island stops: no flights in or out, no traffic, no lights after dark, and guests are asked to stay within their hotel grounds. It is an extraordinary thing to witness, but check the date before booking, because the airport closes completely.
When is the best time for the Gili Islands and Lombok?
May to September, when the seas are calmest and the fast-boat crossings are comfortable. January and February bring the roughest water, and crossings are sometimes cancelled. If a rough boat ride is a concern, travel in the dry season and book a morning departure, when the sea is usually flattest.
Is Bali too hot in the summer?
Not unbearably. Coastal temperatures sit around 28 to 32°C (82 to 90°F) all year with high humidity, and the difference between seasons is small. What changes is the rain. Inland Ubud sits at around 600 feet and is a few degrees cooler, and the highlands and Bromo are genuinely cold before dawn — take a warm layer for the volcano.
