Bali sits just south of the equator, so the temperature barely moves all year and the sea stays warm whatever month you choose. What actually changes is the rain and the crowds, and that is what should drive your timing. The island runs on two seasons, a dry one from roughly April to October and a wet one from November to March, with the peaks of July, August and the Christmas weeks layered on top.
This guide walks the year month by month, with a quick grid for the headline conditions and longer notes on the months that matter most. We have been honest about the trade offs, because the driest, sunniest weeks are also the busiest and priciest, and the cheapest, quietest weeks come with afternoon downpours.
If you want the short answer, aim for the shoulder months of May, June and September. You get dry season weather and gentler crowds and prices than the July and August peak. Below is the fuller picture so you can match the month to the trip you want.
Month by month at a glance
| Month | Air | Sea | Rain | Crowd | Verdict |
|---|---|---|---|---|---|
| January | Warm, humid | Warm, around 29C | Wettest, heavy showers | Quieter after New Year | Low season; cheap and green, but plan around the rain |
| February | Warm, humid | Warm, around 29C | Wet, frequent showers | Quiet | Still wet but good value and lush |
| March | Warm, easing | Warm, around 29C | Wet, easing late month | Quiet | The wet season tailing off; a quiet gamble |
| April | Warm, drier | Warm, around 28C | Drying out | Building | Dry season begins; a lovely, fresher window |
| May | Warm, dry | Warm, around 28C | Mostly dry | Moderate | A top shoulder month; dry and not yet packed |
| June | Warm, dry | Warm, around 28C | Dry | Moderate, building | Excellent; dry season at its most pleasant |
| July | Warm, dry, breezy | Warm, around 27C | Dry | Peak | Glorious weather, but the busiest and priciest |
| August | Warm, dry, breezy | Warm, around 27C | Dry | Peak | Peak season; book early and expect crowds |
| September | Warm, dry | Warm, around 28C | Dry | Easing | A top shoulder month; the peak crowds thin out |
| October | Warm, humid rising | Warm, around 28C | First showers return | Moderate | Dry season fading; still good with the odd shower |
| November | Warm, humid | Warm, around 29C | Wet season starting | Quieter | Greening up; value returns with the rain |
| December | Warm, humid | Warm, around 29C | Wet, heavy late month | Peak over Christmas | Wet, but holiday weeks are busy and pricey |
When each month earns its place
May. One of the best months of the year. The dry season is established, the landscape is still green from the rains, and the heavy peak crowds have not arrived. Beaches are reliably sunny and the west coast surf is picking up, which makes it a strong all round window for swimming, surfing and value before prices climb.
June. Dry season at its most comfortable, with sunny days, lower humidity and a gentle breeze that takes the edge off the heat. Crowds are building toward the peak but it does not yet feel packed, and conditions on both coasts are excellent. A great month for almost any kind of Bali trip.
July. The driest, sunniest weather of the year, which is exactly why it is the busiest and most expensive. Beaches, clubs and roads are full, and accommodation needs booking well ahead. The trade off is dependable weather and lively energy everywhere. The dry trade winds also drive the kitesurfing season at Sanur.
August. The other peak month, with the same superb dry weather and the same crowds and prices as July. If you come now, embrace the buzz, book everything early and use mornings to beat the crowds at the popular beaches and cliffs. The surf on the west coast is typically at its most consistent.
September. Arguably the sweet spot of the year. The peak crowds thin out while the dry, sunny weather holds, so you get July quality conditions with more room to breathe and softer prices. A superb month for beaches, surf and quieter sunsets across the island.
December. A month of two halves. The wet season is underway with humid days and heavy showers, especially late in the month, yet the Christmas and New Year weeks are among the busiest and priciest of the year. Come for the holidays if you want the buzz, but expect rain and book the festive dates early.

Before you go
What is the best month to visit Bali?
For most people it is the shoulder months of May, June or September, when the dry season weather is excellent but the peak crowds and prices of July and August have not taken over. April and October are also good, with a slightly higher chance of a shower.
When is the dry season in Bali?
The dry season runs from roughly April to October, with the sunniest, least humid weather and the lowest rainfall. July and August are the driest and the busiest. The wet season is from around November to March, with warm temperatures but frequent, often heavy showers.
Is the sea warm enough to swim all year?
Yes. Bali's sea stays warm all year, generally around 27 to 29 degrees, so swimming is comfortable in any month. The bigger factors are rain, crowds and which coast you choose, since the calm east coast and the surf west coast behave very differently.
Is it worth visiting Bali in the wet season?
It can be. The wet season from November to March brings lush landscapes, fewer crowds outside the Christmas weeks and better value, and the rain often falls as heavy afternoon showers rather than all day. You just need to plan around the weather and keep some flexibility.
When is Bali most crowded?
July and August are the peak, along with the Christmas and New Year weeks in December. Expect full beaches, busy roads and higher prices then, and book accommodation and popular tables well ahead. For dry weather with fewer people, the May, June and September shoulders are better.
