Thinking about heading to Bali in the fall? You’ll get warm days, fewer crowds, and a noticeable change in the island’s weather as the dry season gives way to wetter months. In Denpasar, average daytime temperatures usually hover between 26°C and 28°C (79°F to 82°F), so it’s hot but still decent for outdoor plans. Nights don’t cool off much, so the air feels warm pretty much all the time.
Rain starts to pick up in October and November, but showers are usually short and followed by sunshine. Humidity climbs too, making the heat feel more intense, but the sea stays perfect for swimming, with water temps around 27–29°C (81–84°F).
This steady warmth, rising humidity, and those quick showers all combine to shape fall in Denpasar. It helps to know what’s coming, whether you’re chilling on the beach, wandering temples, or exploring Bali’s green hills.
Overview of Fall Weather in Denpasar
Fall in Denpasar keeps things warm, with only minor shifts in temperature each day. Rainfall edges up, and you’ll notice more humidity and clouds as the area transitions from dry to wet season.
Key Climate Characteristics
Temperatures in Denpasar during fall stay pretty steady. Daytime highs average 26.6°C to 28.4°C (80°F to 83°F), and nighttime lows land around 23.8°C to 25.5°C (75°F to 78°F). You won’t get big temperature swings, so most people find it comfortable for being outside.
Humidity hovers near 80%, so the air stays moist. It’s sticky, sure, but the warmth is reliable. Sea temps stick around 26.5°C to 28°C (79°F to 82°F), so swimming and water sports are a go all season.
You’ll still get plenty of sun, with 8–9 hours per day on average. But as fall goes on, clouds show up more often. That mix of sun and clouds really sets the tone for this time of year.
Seasonal Weather Patterns
Rainfall rises during fall, from about 24 mm (0.9 in) in September to 62 mm (2.4 in) in November. Rainy days go up too, from about 13 days in September to almost 20 days in November. Showers are usually quick, but sometimes heavy.
Even with more rain, much of the day can still be clear. Mornings often start sunny, and showers roll in later. If you want to do things outside, go earlier, then switch to indoor or shaded activities in the afternoon.
Winds blow at a moderate pace, about 8–14 km/h (5–9 mph), which helps with the humidity. Air pressure and clouds don’t change much, sticking to the tropical climate norm.
Transition from Dry to Wet Season
Fall is when Bali moves from its dry season into the wet season. September still feels dry, with less rain and lots of sun. By October, you’ll notice more showers, and November really signals that rainy season is here.
The change isn’t sudden. Early fall still has plenty of dry days, but by late fall, it feels heavier—more humid and cloudier.
Travelers often like this time since you get a bit of both worlds, with fewer crowds than peak dry season and greener scenery as the rain returns. Beaches, temples, and markets are still open, though you might want to pack for the odd rain shower.
Average Temperatures During Fall
In Denpasar, fall temperatures stay warm and don’t change much month to month. Expect highs in the upper 80s °F and lows in the mid-70s °F, so it’s reliably hot and humid.
Monthly Temperature Trends
Throughout fall, average daily highs in Denpasar sit close to 87°F (31°C). They almost never dip below 84°F (29°C) or climb above 90°F (32°C). The hottest part of the season usually hits in early March, and things cool off a bit by late May.
Nighttime lows average around 76°F (24°C), and these numbers barely budge—just a 2–3 degree difference through the season. You probably won’t notice much change in comfort from month to month.
| Month | Avg High | Avg Low |
|---|---|---|
| March | 88°F / 31°C | 77°F / 25°C |
| April | 87°F / 31°C | 76°F / 24°C |
| May | 86°F / 30°C | 75°F / 24°C |
Humidity stays high, so even a small temperature shift can feel bigger. Early in the season, clouds add to the muggy feeling, especially in March.
Daytime and Nighttime Variations
Daytime highs hit the upper 80s °F, usually peaking in the early afternoon. It’s hot, but coastal breezes can help. The sun is strong, so don’t skip sunscreen—UV levels are up there all season.
At night, temps only drop to the mid-70s °F. It doesn’t cool off enough for chilly evenings, so it stays warm and humid even after sunset.
Since day and night temps are close, you don’t need to change clothes much. Lightweight, breathable stuff works for both day and night. After it rains, the air gets warm and humid again in no time.
Rainfall and Precipitation Patterns
As fall rolls in, Denpasar starts to shift from drier months toward wetter ones. You’ll notice both more rain and more rainy days, which can change how you plan your time outside.
Monthly Rainfall Totals
September usually brings 40–60 mm of rain. Showers are short, and most days stay dry.
By October, rainfall bumps up to about 70 mm, hinting that the wet season is coming. Rain happens more often, but it’s still mostly quick bursts.
November is when things pick up, with 150–200 mm. This jump makes November the real turning point, as the climate goes from mostly dry to regularly wet.
| Month | Average Rainfall (mm) | Typical Rain Days |
|---|---|---|
| September | 40–60 | 1–2 |
| October | ~70 | 2–3 |
| November | 150–200 | 8–12 |
You can see how fast rainfall builds as fall goes on.
Onset of Wet Season
The wet season usually starts showing up in late October and settles in by November. This timing is pretty consistent, though some years shift a bit.
The change is slow. Early October gets late afternoon or evening showers. By November, storms come in heavier and more regularly, sometimes lasting a few hours.
Humidity rises too, making the air feel warmer even though daytime temps stay around 27–29°C. When humidity and rain both climb, you know the monsoon cycle has started.
If you’re visiting in late fall, plan for wetter weather and have backup activities indoors.
Rainy Days and Intensity
In September, you might only see 1–2 rainy days, and the showers are light. The weather still feels like the dry season.
October brings a few more rainy days, usually 2–3. Showers can pop up fast, mostly in the late afternoon.
By November, things shift. Rain comes on 8–12 days, and storms often bring heavy downpours. One shower can dump 20–30 mm at once. Streets might flood briefly, but the water drains out pretty quickly.
The intense November rain really announces the wet season. Expect less sunshine and more clouds, especially in the afternoons.
Humidity Levels in Autumn
Bali’s autumn is humid, with only tiny changes month to month. These humidity levels make the air feel warmer and can affect how comfy you feel outside.
Average Humidity by Month
In Denpasar, relative humidity almost never drops below 80%. September averages around 82%, so the air feels damp. By October, it’s about 82–83%, and in November, it edges up to 84% as the rainy season nears.
So, you can count on humid conditions all season. Unlike places with big seasonal swings, Bali keeps things damp year-round. The difference between months is tiny, maybe 2–3 percentage points.
| Month | Average Humidity |
|---|---|
| September | ~82% |
| October | ~82–83% |
| November | ~84% |
Autumn is definitely one of the more humid times of year, especially as November heads into the wet season.
Impact on Comfort and Activities
High humidity makes it feel hotter than the thermometer says. For example, a 28°C day in October can feel way warmer when humidity hits 83%. Sweat doesn’t evaporate quickly, so you might feel sticky or heavy outside.
If you’re sightseeing, early mornings and late afternoons are more comfortable. Midday can feel pretty intense, especially if you’re walking or biking. Indoor spots with fans or air-con are a nice break during the muggiest hours.
Outdoor stuff like hiking or temple visits is still doable, but bring water and take it slow. The beach is always good, since sea breezes help. By November, expect more clouds and rain showers that add to the damp feeling.
Sunshine, Cloud Cover, and Wind
Fall in Bali keeps daylight pretty steady, but the mix of sun, clouds, and wind changes as the island shifts from dry to wet season. You’ll still get steady warmth, but the skies and breezes change a lot from September to November.
Average Daily Sunshine Hours
September usually brings about 8–9 hours of sunshine per day, making it one of the sunniest times of year. By October, you’ll see a slight drop as humidity and clouds go up.
In November, clouds build up even more, and you get around 6–7 hours per day. Still, daylight lasts close to 12 hours, so there’s plenty of time to be outside.
If you want to hit the beach, dive, or hike, September is your best bet for reliable sunshine. By late October and November, mornings are brighter, but afternoons bring more clouds and sometimes rain.
Cloudiness Trends
Clouds become more common as fall goes on. September skies are often partly cloudy, with lots of clear mornings. By October, you’ll notice more afternoon clouds, especially inland and near the mountains.
In November, skies turn mostly cloudy or overcast for longer stretches. That’s a sure sign the wet season is near. You might still get clear spells, but blue skies don’t last as long as earlier in the season.
More clouds can affect scenic views, too. Coastal spots usually stay clearer than the hills, so if you’re after mountain views, September and early October are your best window.
Typical Wind Speeds
Winds in Bali during fall usually feel light to moderate. In September, the southeast trade winds still show up, bringing a steady breeze along the coast.
These winds often hit around 10–20 km/h (6–12 mph), so the breeze keeps things comfortable even when it’s hot.
By October, winds start to fade as the season shifts. You’ll probably notice calmer days and less cooling air, especially if you’re inland.
In November, the winds change direction as the monsoon approaches. The speeds stay pretty mild, but the air feels heavier and more humid. Sometimes, coastal areas catch a quick gust, but strong winds almost never happen at this time.
Travel Tips for Visiting Denpasar in Fall
Rain picks up during fall in Denpasar, but temperatures stick around the mid-20s °C. You can still get outside and enjoy yourself, just plan around showers, pack light clothes with some rain gear, and keep an eye on changing conditions at Ngurah Rai International Airport.
Best Times for Outdoor Activities
September and October usually have the driest fall weather, with highs near 26–27°C (79–81°F) and less rain than November. These months are your best bet for beach trips, snorkeling, or checking out cultural sights.
Rainfall jumps up in November, often topping 100 mm for the month. Showers can pop up most days, but they’re usually quick and show up in the afternoon or evening.
If you want to dodge the rain, mornings are your friend—skies tend to be clearer. Toss a small umbrella or light rain jacket in your bag so you can keep exploring during sudden showers.
What to Pack for the Season
Go for breathable clothing like cotton shirts, shorts, or light dresses, since the humidity stays high. Make sure you bring a light rain jacket or compact umbrella, especially for November when the rain really starts up.
Pack sandals for dry days, and water-resistant shoes for when it gets wet. Quick-dry fabrics help a lot, since laundry can take forever to dry in the damp air.
Don’t forget sunscreen, sunglasses, and a wide-brim hat for sun protection. Bali’s UV levels stay strong, even if it’s cloudy. A small backpack or waterproof bag is handy for carrying your stuff and keeping electronics and documents safe from surprise rain.
Ngurah Rai International Airport Weather Considerations
Ngurah Rai International Airport sits just south of Denpasar and operates all year. Fall weather sometimes shakes things up for flight schedules.
In September and October, flights usually run without much trouble. But when November rolls around, heavier rain and the odd thunderstorm can lead to short delays.
The airport built its runways and taxiways to handle those tropical downpours, so long closures almost never happen. Still, when the rain gets intense, visibility can drop fast, and that might affect arrivals or departures.
If you’re heading to the airport, leave yourself extra time. Roads around Kuta and Denpasar sometimes flood during heavy rain, and that can slow everything down.
It helps to keep your connections flexible and watch for updates from your airline. That way, you’ll dodge some stress if the weather decides not to cooperate.
