- Wet season runs November–March, with January the wettest month and August the driest.
- Rain usually falls in short, heavy bursts in the afternoon or evening — mornings are often clear.
- Pros: fewer crowds, lower flight and hotel prices, lush green rice terraces, waterfalls at full flow, and good surf on the east coast.
- Cons: high humidity, rougher seas that can cancel Gili Islands and Nusa Penida boats, and a seasonal rise in dengue-carrying mosquitoes.
- Verdict: worth it for budget, culture, and quiet-seekers — less so for a trip built entirely around the beach.
This guide is the deep dive on Bali’s wet season specifically. For the full-year picture, including the busy dry-season months, see our Best Time to Visit Bali overview.
When Is Bali’s Rainy Season?
Bali’s wet season runs from around November to March, driven by the northwest monsoon that also soaks much of Indonesia during these months.
December, January, and February are the wettest stretch, and January is consistently the rainiest month of the year.
By late March, the rain starts to ease into a transition period, with more sunshine breaking through between showers.
Bali Rainfall by Month: What the Numbers Show
Bali gets about 1,715mm of rain a year on average, but it isn’t spread evenly — more than half of it falls across just three months.
January is the wettest month at 350mm of rain over roughly 19 rainy days, while August is the driest at just 15mm over about 3 rainy days.

Dry season (Apr–Oct)
What the Rain Actually Feels Like on the Ground
Most wet-season days follow a simple pattern: clear or partly cloudy mornings, then a build-up of clouds and a heavy downpour sometime in the afternoon or evening.
These bursts are often intense but short, sometimes over within an hour, leaving the rest of the day dry.
January and February are the exception — you can get multi-day wet stretches where the sun barely breaks through, especially in a strong monsoon year.
- Morning (until around 11am): Usually clear or lightly cloudy, and the best window for sightseeing.
- Midday to afternoon: Clouds build and short, heavy downpours are common.
- Evening: Rain usually clears, leaving humid but dry nights.
The Honest Upside of a Wet-Season Trip
Rainy season is Bali’s off-peak stretch, and that shows up in every part of the trip.
- Fewer crowds: Popular spots like rice terraces, temples, and beach clubs are noticeably quieter than in the July–August peak.
- Lower prices: Flights and Bali hotels both tend to drop in price outside the dry-season rush.
- Lush scenery: Rice terraces turn a deeper green and waterfalls run at full flow after heavy rain.
- East-coast surf: The northwest monsoon sends swell into east-side breaks like Keramas, Sanur, and Nusa Dua, which are at their best from November to March.
The Honest Downsides
The trade-offs are real, and they matter most for beach-focused travelers.
- Humidity: Even between downpours, the air stays warm and sticky.
- Rougher seas: Fast boats to the Gili Islands and Nusa Penida are more prone to delays and cancellations when waves pick up, especially from December to February.
- Occasional flooding: Heavy downpours can flood low-lying roads and rice fields for a few hours at a time.
- More mosquitoes: Standing water after rain means more mosquitoes, and dengue fever cases in Indonesia typically climb during the wet season.
What to Pack and Where to Go When It Rains
A little planning turns a wet-season trip from a gamble into a genuinely relaxed one.
- Pack: a light rain jacket, quick-dry clothing, a dry bag for electronics, mosquito repellent, and sandals that dry fast.
- Lean into: Ubud’s indoor culture (art museums, cooking classes, spas), temple visits, and waterfalls that are more dramatic after rain.
- Build in flexibility: keep island-hopping day trips and beach-club plans loose in case of rough seas or a rained-out afternoon.
If you’re combining Bali with other stops around Indonesia, hotel rates island-wide tend to follow the same seasonal dip.
Is Bali Worth Visiting in the Rainy Season? The Verdict
Yes, if you want a cheaper, quieter, greener trip and don’t mind building your days around an afternoon downpour.
Less so if a guaranteed sunny beach holiday is the whole point of your trip — the dry season, from April to October, is the safer bet for that.
Frequently Asked Questions
When is Bali’s rainy season?
Bali’s rainy season runs roughly from November to March, with December through February the wettest stretch and January the peak month.
Does it rain all day in Bali during rainy season?
Usually not. Most days bring clear mornings and a heavy but short downpour in the afternoon or evening, though January and February can bring longer wet stretches.
Is Bali worth visiting in rainy season?
Yes, for travelers who want fewer crowds, lower prices, and lush scenery. It’s a tougher call if your trip is built entirely around beach days.
What should I pack for Bali’s rainy season?
A light rain jacket, quick-dry clothes, a dry bag for electronics, mosquito repellent, and sandals that dry quickly all help.
Are boats to the Gili Islands and Nusa Penida affected by rainy season?
Yes. Rougher seas between December and February regularly cause fast-boat delays or cancellations on these routes, so keep island-hopping plans flexible.
Is dengue fever a bigger risk in Bali during rainy season?
Yes. Health authorities note that dengue cases in Indonesia typically rise during the rainy season as mosquito populations increase, so pack repellent and choose mosquito-proof accommodation.
Planning Around the Rain
Bali’s wet season is a trade-off, not a dealbreaker: quieter, cheaper, and greener, in exchange for afternoon downpours and a bit less certainty on beach days.
Whichever week you choose, compare fares and hotel deals before you book — prices swing more in Bali’s wet season than the weather does.
