Asu
Asu is Indonesia's best-kept secret left—a pristine, barreling wave off a speck of an island in the Hinako group that few surfers ever reach. The journey here is an adventure in itself: flights, boat transfers, and basic island living, but the reward is potentially perfect waves with a handful of other surfers at most. The left reels along a coral-strewn reef, offering long, makeable barrels when the Indian Ocean delivers. Asu represents the ultimate surf trip ethos: go further, score better, embrace the simple life.

Frequently Asked Questions
What kind of wave is Asu?
Asu is a reef break in Hinako Islands, Indonesia, that mostly breaks left.
What swell works best at Asu?
Asu picks up swell from the SSW round to the WSW, and it's best when it's coming straight out of the SW. It starts working at around 1m and handles up to about 3m, with the sweet spot around 1.9 to 2.5m. Period matters too: aim for 14s or longer, as anything under 10s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
What wind is offshore at Asu?
A SE wind is dead offshore at Asu, and anything from the E round to the S keeps it clean. The morning is typically the best window, roughly 6am to 11am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.

Asu is at its best around the mid to high tide, roughly 0.5m to 1.5m on the local chart.

The most reliable run of swell at Asu comes Apr to Oct. April-October. Indian Ocean swells.
How cold is the water at Asu?
