Tanjung Aan surf forecast by the hour
Our hourly table scores each hour against what this reef likes. It works best with swell from the south to the west, wind from the north and a mid-to-high tide. Our forecast is for open water near the shore, so waves inside more sheltered corners will often be smaller.

Forecast point: Tanjung Aan (-8.912, 116.329). Waves = estimated breaking height at the beach. Data: Open-Meteo wave and weather models (CC BY 4.0). Generated using E.U. Copernicus Marine Service Information. Surf at your own risk.
Watch the tide column first. At dead low tide parts of the reef can get very shallow or even dry out. Plan your sessions for the mid-to-high part of the tide.
Surfing Tanjung Aan: the peak and nearby breaks
Tanjung Aan is a fairly exposed reef that gets most of its waves from groundswell. Waves break well out in the middle of the bay, so expect a long paddle or a short boat ride. Several other reefs lie within about 5 km if Aan is not working.
Tanjung Aan
Reef breakRight and leftThe right is the main wave here. It peels slowly and gives you time to get to your feet, which suits longboards and practice on turns. The left is shorter and gentler, and it is a good choice when the right gets busy.
The bottom is a mix of deep reef and sand. Our own setup still rates it intermediate+ because of the shallow reef, the boat access and the currents. Sources: lmbksurfhouse.com

What Tanjung Aan needs to fire
These are the exact rules behind Kiwi's rating for this spot. Every hour of the forecast is scored on all four, then turned into a rating of 1 to 5 stars.
Swell
South to west swell
The reef faces south (about 190°) and takes swell from between 180° and 250°.
Wind
Offshore from the north
The best wind blows from the north, around 20°. Winds from the south side of the compass blow onshore on this south-facing reef.
Tide
Mid to high tide
Mid-to-high tide works best here. Shallow reef is one of the listed hazards.
Size
Ideal 1.2 to 2.5 m
Waves under about 0.8 m are usually too small, and 1.2–2.5 m is the sweet spot. Above about 3.5 m it is too big.
Shortcut: look for a 1.2–2.5 m south-to-west swell with a northerly wind on a mid-to-high tide.
The best months to surf Tanjung Aan
We replayed Kiwi's rating on every day of the last year and counted how often Tanjung Aan's best window reached 4 or 5 stars.
Nov–DecThe best run of the year
December is the strongest month, with 32% of days rated 4+ and 52% rated 3+. November follows with 17% and 47%.
Jan–FebQuieter than you might expect
Only 3–4% of days reach 4+, and 7–13% reach 3+. One local guide calls the wet season the best time overall, so stay flexible and check the forecast.
Mar–AprA second good window
April matches November, with 17% of days at 4+ and 47% at 3+. One forecaster rates March as the cleanest month, with clean waves about 39% of the time.
May–OctDry season, mostly off
Good days are rare, and from August to October almost none reach 3+. Trade winds in the dry season can leave the bay choppy.
Before you go
Hazards
Watch for the shallow reef and the currents. Rips and rocks are also reported here.
At dead low tide some sections can get very shallow or even dry. Check the tide before you go out. Sources: surf-forecast.com · lmbksurfhouse.com
Getting there
From Kuta it is about a 15-minute scooter ride east on a paved road through the coastal hills.
The nearest airport is Selaparang (Mataram), AMI, about 48 km away in a straight line. Bali's Denpasar airport, DPS, is about 129 km away. Sources: lmbksurfhouse.com · surf-forecast.com
Parking and paddling out
There is plenty of parking on the beach, and local warungs sell drinks such as coconuts.
The paddle out takes about 15–20 minutes. Many surfers pay a local boatman a small fee to take them to the peak in an outrigger perahu and collect them afterwards. Sources: lmbksurfhouse.com
Boards
Several warungs on the sand rent longboards and funboards. Sources: lmbksurfhouse.com
Crowds and etiquette
Reports differ: one forecaster says it is rarely crowded, while a local surf house lists the crowd as busy.
When the right gets packed, the left is a calmer option. Sources: surf-forecast.com · lmbksurfhouse.com
Water temperature and what to wear
The sea stays warm all year, from about 26.5°C in August and September to about 29.8°C in December.

Best time of day
Plan around the tide rather than the clock, and aim for the mid-to-high stage.
In early November the sun rises around 5:45 and sets around 6:10 pm local time (WITA). Sources: lmbksurfhouse.com · surf-forecast.com
After the surf
The white-sand bay is good for a swim, and Bukit Merese hill is a popular place to watch the sunset. Sources: lmbksurfhouse.com
Where the numbers come from
The method
Kiwi takes Open-Meteo's wave and wind models (ECMWF WAM, Météo-France, NOAA GFS and Open-Meteo's best-match blend) at a point about 5 km off Tanjung Aan. There is no buoy correction here yet: these are the models as they come.
Each hour is scored on the four rules above (swell, wind, tide, size). The stars are calibrated on a full year of data for Indonesia, so 4 stars at Tanjung Aan is a genuinely good day by that country's standard.
What we can say
The season chart and the stars use the same rules, replayed on the archive: a month marked good was good by these rules, not by a surf report.
Without a buoy nearby, the size at the beach is our model's estimate, not a measurement.
Tanjung Aan surf questions
Is Tanjung Aan good for beginners?
A local surf house calls it perfect for beginners and longboarders, with a soft wave and water deep enough over the reef at mid-to-high tide. Our setup rates it intermediate+ because of the shallow reef, the currents and the boat access.
When is the best time to surf Tanjung Aan?
December is the strongest month, with 52% of days rated 3+. November and April are next, at 47% each. The months from August to October rarely deliver.
How cold is the water in Tanjung Aan in December?
It is not cold at all: the sea averages about 29.8°C in December. Wear at least a rash vest to keep the UV off.
Do I need a boat to surf Tanjung Aan?
No, but it helps. You can paddle out in about 15–20 minutes, or pay a local boatman a small fee to drop you at the peak.
What tide is best at Tanjung Aan?
Mid-to-high tide is best. At dead low tide the reef can get very shallow or dry in places.
How do I get to Tanjung Aan from Kuta Lombok?
It is about a 15-minute scooter ride east of Kuta on a paved coastal road. There is plenty of parking on the beach.
