When is the best time to visit Bali? It depends on what you are optimising for: reliable beach weather, fewer people, or lower rates. This guide covers the weather month by month, when the crowds arrive, how prices move, and which window suits each activity, including scuba diving in Bali.
We run a dive centre in Sanur and we get asked this question at check-in almost every day, usually by people who booked flights first and are now working out what they have walked into. Choosing when to come matters, because the month affects everything from rainfall to room rates. Travelling outside July and August can cut your hotel bill roughly in half, and it changes what you see underwater on a Nusa Penida diving day trip too.
The short answer: the best time to visit Bali is the dry season, April to October. May, June, and September are the strongest months, because the weather is settled, the crowds are thinner than the July and August peak, and hotel rates sit well below peak pricing.
In this guide you will:
- Understand Bali's two seasons and how the weather behaves through the year.
- See when peak and low season fall, and what each one costs you.
- Get a month-by-month breakdown of rainfall, temperature, crowds and prices.
- Work out the right window for diving, surfing, hiking and the big festivals.
- Find the cheapest weeks to travel without wrecking the trip.
Bali's Seasons at a Glance
Most people land on this page wanting one specific fact rather than a full guide, so here are the direct answers first. The detail follows underneath.
What are the seasons in Bali?
Bali has two seasons rather than four. The dry season runs April to October and the wet season runs November to March. Daytime air temperature barely shifts between them, sitting around 29 to 32°C all year. What actually changes is rainfall, humidity, and how busy the island feels.
When is the dry season in Bali?
Bali's dry season runs from April to October. August is the driest month, with roughly 42mm of rain across three or four wet days. June to September brings the clearest skies and the lowest humidity. It is also when underwater visibility off Sanur and Nusa Penida is at its best.
When is the rainy season in Bali?
Bali's rainy season runs from November to March. January is the wettest month, with about 296mm falling over roughly 22 days. It rarely rains all day. The usual pattern is a heavy afternoon downpour lasting one to two hours, then clear skies again by evening.
When is peak season in Bali?
Bali has two peak periods. The main one is July and August, driven by European summer holidays and Australian school breaks. The second runs from around 20 December to 5 January, when Christmas and New Year fill the island despite it falling in the middle of the wet season.
When is low season in Bali?
Low season covers February and March, the stretch from late January once New Year clears, and early November. Hotels discount heavily, often 40 to 50 percent below peak rates, and the major sights are quiet. You trade that against daily rain and, in January and February, murky water along the south coast.
When is Bali hot, and when is it cold?
Bali is hottest from November to April, when daytime highs reach 31 to 32°C and the humidity makes it feel warmer still. The coolest stretch is July and August, with highs near 29°C and Sanur nights dropping to about 23°C. It is never cold at sea level, though Kintamani and Mount Batur can fall to 10°C before dawn.
Which are the best months to visit Bali?
May, June, and September are the best months to visit Bali. All three sit inside the dry season with settled weather and low rainfall, but they fall outside the July and August crowd peak, so room rates stay mid-range and the popular sites are bearable. September is our own pick.
What is the cheapest time to visit Bali?
Late January through to early March is the cheapest time to visit Bali. Room rates fall 40 to 50 percent below July levels and airfares follow. November and the first half of December are also cheap, before the Christmas surge arrives around the 20th.
When should you not visit Bali?
Two windows we steer people away from. Late December to early January combines peak crowds with peak rain, which is the worst of both. And mid-January to February is poor if the trip is built around beaches, because monsoon runoff pushes debris onto the south coast. Everything else works with realistic expectations.
Bali's Climate: Two Seasons, One Temperature
Bali has a tropical climate with two seasons, which makes trip planning simpler than in places with four. Temperature is remarkably stable. On the coast and in central districts like Ubud, daytime highs run between 29°C and 32°C (84°F to 90°F) whatever month you arrive, and the sea never drops below 26°C at the surface.
The island's location near the equator, 8 degrees south of the equator in the southern hemisphere, keeps the temperature stable while causing big changes in rainfall between seasons. Knowing these patterns helps you plan for warm weather no matter when you go, and it also helps you plan around rain and humidity levels.
What the Dry Season Is Like (April to October)
Bali's dry season lasts from April to October. During this time, the air is dry, the skies are clear, and there is little rain. This makes it a great time for beach activities and outdoor experiences. August is the driest month, with only 42mm of rain. From May to September, there are only 4-8 days of rain each month on average.
In the dry season the days are sunny and the evenings cool off, which takes the edge off the heat. Tourism peaks at the same time, so beach clubs in Seminyak fill up and hotel prices climb. Plenty of people pay it happily for the weather. If you are staying on that side of the island, our Seminyak, Canggu and Ubud dive pickup guide has the real transfer times.
What the Wet Season Is Like (November to March)
From November to March the wet season brings afternoon showers, higher humidity, and landscapes that turn a ridiculous shade of green. January is heaviest at roughly 296mm. The rain arrives in bursts rather than lasting all day, which is why diving Bali in the rainy season still works better than most visitors expect.
During the rainy months, hotels are often 50% cheaper, there are fewer people at temples and sites, and it's a great time for cultural events and spa retreats. The rain does make things harder, including treacherous hiking paths, canceled tours, and beach pollution from monsoon runoff in January and February. But those who are willing to put up with it will discover rewarding experiences in the beautiful surroundings.
Those seasonal patterns drive the second thing you need to plan around, which is when everybody else turns up.
Peak Season, Low Season and Shoulder Season in Bali
Bali's tourist seasons are very similar to its weather patterns, but there are also extra busy times around school holidays and the holiday season that you should know about when planning your Bali trip.
Why July, August and Christmas Cost More
The high season lasts from July to August, when European summer vacations bring a lot of people to southern resorts. It also lasts from December to January, when the holidays and Australian school vacations bring in even more people. Even though it rains a lot in late December, Christmas and New Year's Eve bring in as many people as the busiest times of the year.
During the busiest times of the year, expect long lines at famous sites, high prices for hotels, and the need to make reservations for restaurants and activities well in advance. The trade-off is real, though. July and August deliver the most dependable dry weather of the year, highs around 29°C with barely any rain, which is what makes them the best beach months and the peak of the diving calendar.
One catch for divers. The dry season is also thermocline season. Surface water off Sanur stays around 26 to 27°C in July and August, but drop below about 15 metres at Crystal Bay or Nusa Penida and you can cross into 16°C, occasionally as low as 13 to 14°C. That cold water is exactly what draws the mola mola to Bali, so it is a trade rather than a problem. Bring a 5mm suit and a hood.
What You Gain by Coming in Low Season
For those who are open to change, the low season (November to March, not including holidays) has some great benefits. Lower pricing, less people at Ubud's rice paddies and main temples, and a slower pace give you more time to connect with Balinese culture.
Days stay warm, 31 to 32°C, and the quiet beaches and spas are a genuine pleasure. It suits long-stay digital nomads, couples who want space, and anyone who values the saving over guaranteed sunshine. January and February are the cheapest months of the year, with the caveat that beach conditions suffer from monsoon runoff. Water clarity holds up far better on the east coast, which is why we shift trips to Tulamben and the USAT Liberty wreck when the south is churned up.
Shoulder Season: April to June, September to October
The shoulder season, April to early June and September to October, is the right answer for most visitors. Daytime highs of 30 to 32°C, little rain, noticeably fewer people, and accommodation priced sensibly rather than opportunistically.
May and September stand out because the weather is close to perfect and visitor numbers have not spiked, so hotel deals are better and the popular sites are accessible. April carries 9 rainy days on its way into the dry season and October carries 12 on the way out. Both are a fair trade for the drop in crowds. September is when we run our best PADI Open Water Diver courses in Bali, because the sea has settled and the classes are small.
All of which is easier to act on once you see it broken down month by month.
Bali Weather Month by Month
Here is the whole year in one place, so you can match your available dates against what Bali is actually doing that month.
Every Month Compared: Rain, Heat, Crowds and Cost
Every month of the year, with the figures we actually quote to guests. Rain is the monthly total, air is the average daytime high, and sea is the surface temperature off Sanur. Expect several degrees colder below the thermocline from July to October.
| Month | Rain | Air high | Sea | Crowds | Verdict |
|---|---|---|---|---|---|
| January | 296mm | 31°C | 29°C | Low | Cheapest, wettest |
| February | 244mm | 31°C | 29°C | Low | Cheap, poor beaches |
| March | 210mm | 31°C | 29°C | Low | Drying out, Nyepi |
| April | 131mm | 32°C | 29°C | Moderate | Great value |
| May | 74mm | 31°C | 28°C | Moderate | Excellent all round |
| June | 57mm | 30°C | 27°C | Moderate | Clear skies |
| July | 53mm | 29°C | 26°C | High | Great weather, packed |
| August | 42mm | 29°C | 26°C | Highest | Driest, busiest |
| September | 53mm | 30°C | 26°C | Moderate | Our pick |
| October | 68mm | 31°C | 27°C | Moderate | Good value, rain returns |
| November | 154mm | 32°C | 28°C | Low | Quiet, showers start |
| December | 260mm | 31°C | 29°C | Low to Highest | Wet, then holiday rush |
May, June, and September are the sweet spot: dry-season weather without peak-season pricing. Pay July and August rates only if school holidays force your hand, or if you specifically want Bali at its loudest. For divers there is one exception worth knowing, which is that the mola mola window falls squarely inside those expensive months.
What Each Month Is Actually Like
January. 296mm of rain over about 22 days, highs of 31°C. The wettest month and the cheapest. Good for spa stays, cooking classes and temples. South-coast beaches collect monsoon debris, so plan around that.
February. 244mm, 20 wet days, 31°C. Second-cheapest month. Warm sea at 29°C, but visibility on the south coast is the worst of the year. East-coast sites hold up.
March. 210mm and easing, 31°C. Nyepi, the Day of Silence, falls in March on the lunar calendar. The airport closes for 24 hours and the whole island stops, which is either the highlight of your trip or a logistical headache depending on how you plan for it.
April. 131mm across 9 wet days, highs of 32°C. The dry season takes hold and the value is excellent, because rates have not caught up with the weather yet. Sea at 29°C and flat.
May. 74mm, 7 wet days, 31°C. Settled and bright, with visibility building at Nusa Penida. Moderate crowds and mid-range pricing. One of the three months we recommend most often.
June. 57mm, 5 wet days, 30°C. Blue skies, dropping humidity, and 27°C surface water. Crowds are building but have not peaked. Strong month for a try dive in Bali because the sea is calm and the classes are not yet full.
July. 53mm, 4 wet days, 29°C. Peak season proper. Hot dry days, packed beach clubs, premium rates, and the Bali Arts Festival running through the month. Thermoclines start at Penida, which means the sunfish are on their way.
August. 42mm, 3 wet days, 29°C. The driest month and the busiest. Independence Day on 17 August fills the island further. Surface water 26°C, and 16°C or colder below the thermocline. Prime mola mola season.
September. 53mm, 4 wet days, 30°C. Our favourite month. The Europeans have gone home, the weather has not turned, prices have dropped back, and the mola mola are still around into early October.
October. 68mm across 12 wet days, 31°C. The transition. Good value with occasional afternoon rain. Manta activity at Manta Point in Nusa Penida picks up as the sunfish leave.
November. 154mm, 15 wet days, 32°C. The wet season begins and prices fall. Beach time is still viable between showers, and the first half of the month is genuinely quiet.
December. 260mm, 19 wet days, 31°C. Wet and cheap until around the 20th, then the holiday period arrives and rates jump to peak levels despite the rain. The worst value fortnight of the year.
These monthly patterns directly inform which activities work best during your planned visit.
Best Time for Diving, Surfing, Festivals and Hiking
Different activities have different best times to do them, depending on the Bali weather, the sea conditions, and the time of year.
Surfing, Diving and Snorkeling
From April to October, the surf breaks on the west coast at Canggu and Uluwatu are at their best because the swells are steady and the winds are offshore. From May to September, the waves are the ideal for intermediate surfers and the seas are the calmest.
Visibility reaches 20 to 30 metres in the dry season, which is why Nusa Penida diving and the east-coast sites at Amed and Padang Bai peak then. Wet-season swell makes boat movements harder and cuts visibility, though rarely to the point of cancelling. Mola mola run mid-July to early October. If you would rather stay on the surface, snorkeling in Bali follows the same seasonal pattern. Our full breakdown of currents, thermoclines and visibility is in the Bali diving conditions guide.
Nyepi, Galungan and the Bali Arts Festival
Important festivals on the Balinese cultural calendar make for distinctive travel experiences. Nyepi, which usually happens in March, shuts down the whole island for a day of stillness. Flights are grounded and the streets are empty, giving people a deep cultural experience.
The Balinese calendar has 210 days, and Galungan celebrations happen twice a year. Temples are filled with offerings and ceremonies. The Bali Arts Festival, which features traditional dance, music, and crafts, runs from the middle of July until the end of August, which is also the busiest time of year. Independence Day, which is on August 17, is celebrated with patriotic events all around the island. When you go to temples during significant events, you can have real experiences, but you have to be mindful of the time and dress appropriately.
Mount Batur and Bali's Waterfalls
The greatest time to hike Mount Batur for dawn views is during the dry season, when the trails are sturdy and the skies are clear, giving you a wide view. The weather in April through October also makes it easier to hike in West Bali National Park.
Waterfalls force a choice. Wet-season flows are fuller and far more dramatic, but the paths are slick and the drives are longer. Dry-season flows are tamer and the footing is safer. Our guide to the best waterfalls in Bali has current entry fees and honest drive times for each one. The rice terraces at Tegallalang and Jatiluwih stay green year round, but clear skies make dry-season photos better. One thing divers forget: several of these sit high enough to count as altitude, so check our no-fly and altitude guidance before combining them with a dive day.
The Planning Problems We Hear Most Often
When organizing their trip to Bali, travelers often have trouble figuring out when to go. These useful methods deal with the most frequent situations.
Getting Dry-Season Weather on a Low-Season Budget
April, May, late September, or October are good months for vacationers who want nice Bali weather but don't want to pay peak season prices. These shoulder season windows give you sunny days at prices that are far lower than in July and August. For the best availability at shoulder season pricing, book your Bali holiday 2 to 3 months in advance.
How to Dodge the Crowds
If you want to avoid crowds while still having great weather, go in early June or September. Both months have almost the same weather as the peak months, but there are a lot fewer tourists. Come in the middle of the week instead of on the weekends and check out northern areas like Lovina or West Bali National Park, where there are fewer tourists all year round, no matter the season.
Making a Wet-Season Trip Work
For your Bali holiday, plan outdoor activities in the morning before the usual afternoon showers if you can only go during the rainy months. Plan cultural activities, culinary courses, and spa days for rainy days, and book places to stay that have covered areas. Beach plans in January and February need to be flexible, but the rewards are peace and quiet and stunning landscape photography during storm breaks.
Bali has great things to do all year round, but the key is to make sure your expectations fit the realities of the season. This way you won't get disappointed about your Bali holiday.
When to Come if You Are Coming to Dive
This is the part most general Bali guides skip, and it is the part we actually know. The best month for a Bali dive trip is not automatically the best month for a Bali holiday.
If you want the widest range of sites in the most settled conditions, come between May and October. Boat access to Nusa Penida is reliable, visibility is at its annual best, and the crossing is comfortable. If you specifically want mola mola, you have a narrower window: mid-July to early October, peaking through August and September. Those are also the coldest and busiest weeks of the year, so you are paying twice for the privilege.
Manta rays are the opposite case. They are resident at Manta Point year round and we see them on roughly nine out of ten trips, but sightings are most consistent from November through April, when the sunfish crowds have gone. That makes the wet season a genuinely good choice for big-animal diving, which surprises people.
For training, the wet season is underrated. Water sits at 28 to 30°C, so an Open Water course in Bali is more comfortable in January than in August, and groups are smaller. We will be honest about the downside: on roughly 5 to 10 days a year the Penida crossing is not safe and we move the trip to Tulamben instead. We would rather do that than put people on a bad boat ride.
Whichever month you pick, base yourself somewhere that shortens the drive. Our guide to where to stay in Bali for diving explains why most divers end up in Sanur, and our dive centre in Sanur is a ten-minute walk from the beach the boats leave from. Current Bali diving prices do not change by season, which is worth knowing when hotels double theirs.
Our Short Answer, and What to Book Next
Come in the dry season, April to October, and aim for May, June, or September if you can choose freely. The weather is as good as July and August, the island is quieter, and you keep the difference in your pocket. Take July and August if you want the mola mola or if school holidays decide for you. Take the wet season if budget matters more than sunshine, and expect warmer water, cheaper rooms, and better manta odds as compensation. If it is your first trip, start with our beginner's guide to diving in Bali.
Immediate action steps:
Choose your top priority (weather, budget, or specific activities) and then find the month that fits that goal in our guide.
Make flight reservations 3-4 months in advance for peak season and 6-8 weeks in advance for shoulder periods
Look for places to stay in the area you want to be, southern beaches for nightlife and water sports, central Bali for culture, and northern Bali for peace and quiet.
If you're interested in cultural events, look at the Balinese lunar calendar to find out when they are.
Worth reading before you book: Bali visa requirements for 2026, since most nationalities can still get a visa on arrival, our Bali diving packing list, which changes depending on which season you land in, and an honest answer on whether Bali is safe. If you are still deciding between dive towns, compare Tulamben, Amed and Padang Bai.
Useful Checks Before You Book
Weather monitoring: Indonesian meteorology services give reliable short-term forecasts, so check the weather in Bali 7 to 10 days before you leave to help you decide what to take. However, remember that the internet weather apps are not reliable; they are notorious to display rain on a sunny day in Bali.
Festival calendars: The dates of Balinese ceremonies change every year based on the lunar calendar. Local tourism organizations put out yearly calendars.
Booking platforms: Major platforms provide seasonal bargains, especially for dates in the shoulder season. Set price alerts for your desired months to catch drops.
Visa information: Indonesian immigration websites list the most up-to-date admission requirements and who can get a visa on arrival by nationality.
