You’ve probably seen the photos. Those limestone cliffs, the surfers carving through glassy turquoise walls, and that golden hour light hitting the Uluwatu Temple just right. It looks like eternal summer. But honestly, if you roll into the Bukit Peninsula without checking the forecast, you might end up staring at a wall of gray rain or, worse, getting absolutely fried by a UV index that doesn't play around.
The weather in Uluwatu Bali is a bit of a weird beast. It’s drier than the rest of the island, which is great, but it’s also exposed. You’re on a limestone plateau. There’s no jungle canopy to hide under like in Ubud. When it’s hot, it’s hot. When the wind shifts in November, the world-class surf spots basically turn into a choppy mess overnight.
The Two-Season Reality (and the Secret Third One)
Bali basically has two speeds: Wet and Dry. Because Uluwatu is on the southern tip, it's often the last place to start raining and the first place to dry out.
The Dry Season (April to October)
This is the "poster child" weather. You get southeast trade winds that blow offshore, grooming the waves at places like Bingin and Padang Padang into perfection. Humidity drops to around 75%—which, for the tropics, feels downright crisp.
The Wet Season (November to March)
Expect humidity to spike to 85% or higher. January is the peak of the madness. You’ll get these massive tropical dumpings that last an hour and then disappear. The "West Coast" (Uluwatu side) gets onshore winds, so the water gets messy. Most surfers head to the East Coast (Nusa Dua or Sanur) during these months.

The Shoulder Months (April & October)
These are the sweet spots. In October, the crowds start thinning out, but the rains haven't fully committed yet. You get "glassy" mornings where the ocean looks like a mirror because the winds are transitioning. It's unpredictable, but when it's good, it's the best weather you'll ever experience.
Monthly Breakdown: What to Actually Expect
If you're planning a trip, don't just look at the 30°C average. That number never changes. What changes is how much you'll sweat.
- January & February: Wet. Very wet. We're talking 300mm+ of rain. Expect mosquitoes to be out in force. It's the cheapest time to grab a villa, though.
- March: The transition. It’s hot. Like, "I need to live in the pool" hot. Humidity is high, and the wind is light.
- April: The surf season kicks off. The trade winds start blowing from the southeast.
- May to August: Peak season. Clear blue skies every single day. The UV index often hits 12 or 13, which is "burn in 10 minutes" territory.
- September: Still dry, but the grass on the cliffs starts turning brown and golden. It looks more like Mediterranean summer than tropical jungle.
- October: The humidity starts creeping back. You might get a few afternoon thunderstorms that clear the air.
- November & December: The rain returns. Usually, it’s a heavy burst at 4 PM, then it clears up for dinner.
The "Uluwatu Microclimate" is Real
People often get confused when it’s pouring in Seminyak but bone-dry in Uluwatu. That’s because the Bukit Peninsula is a raised limestone plateau. It doesn't have the high mountains that trap clouds like central Bali does.
According to local surf guides and data from sites like SwellArchive, Uluwatu handles the wind better than almost anywhere else on the island. Even in the "bad" months, the mornings can be surprisingly clear.

The cliffside wind is another factor. If you're staying at a clifftop resort, that breeze is a lifesaver. It can be 32°C, but the constant ocean air makes it feel like 27°C. Move one mile inland to the main road (Jl. Raya Uluwatu), and you’ll feel the heat radiating off the asphalt immediately.
Surfing and the Wind: A Love Story
The weather in Uluwatu Bali dictates the surf. Period.
Between May and September, the Indian Ocean sends massive groundswells straight at the Bukit. Because the wind is blowing from the land out to sea (offshore), the waves stay open and clean. If you are a beginner, stay away from Uluwatu during these months. The waves can hit 10-12 feet easily.
In the wet season, the wind flips. It blows from the ocean onto the land (onshore). This "crushes" the waves. While it's not great for pro-level surfing, it’s actually a decent time for learners at places like Dreamland, as the power of the swell is much lower.

Survival Tips for the Bukit Heat
Honestly, the sun here is different. You're closer to the equator, and the limestone reflects the light.
- Zinc is your friend. Regular sunscreen washes off in the surf or melts off in the humidity. Get the thick, colored stuff.
- Morning vs. Afternoon. Do your temple visits or hikes (like the stairs at Green Bowl) before 9 AM. By 11 AM, the cliffs become an oven.
- Hydration isn't a suggestion. You’ll see locals drinking Es Kelapa Muda (young coconut water) for a reason. It’s full of electrolytes that help you survive the 90% humidity days.
What to Pack (Besides a Swimsuit)
You don't need much.
Bring a very light raincoat if you’re visiting between November and March. Don't bother with heavy Gore-Tex; you’ll just sweat inside it. A cheap plastic poncho from a Circle K usually does the trick for scooter rides.
For the dry season, a light hoodie is actually useful. If you're riding a scooter at night across the Bukit, the wind can actually feel chilly when the temperature "drops" to 24°C.
Actionable Steps for Your Trip
- Check the Wind: Use an app like Windy or Magicseaweed. If the wind is from the Southeast, head to the Uluwatu side. If it's from the West, go to Nusa Dua.
- Monitor the UV: If the UV index is above 10 (which is almost every day between 11 AM and 3 PM), stay in the shade or under an umbrella at Sundays Beach Club.
- Book for the "Shoulder": If you want the best balance of price and weather, aim for May or September. You’ll get the dry weather without the July crowds.
- Avoid the "Trash Tide": In the peak of the rainy season (Jan/Feb), the winds can bring plastic debris onto some western beaches. Stick to clifftop pools or the cleaner eastern shores during these weeks.
