Asu & Hinako Islands Surf Guide

Surfing in Asu & the Hinako Islands, North Sumatra

Located off the west coast of Nias, the Hinako Islands are a scattered group of small, remote islands that have quietly become a go-to for surfers chasing perfect, uncrowded reef breaks. At the heart of this region lies Asu, a long, powerful left-hander that rivals some of Indonesia’s best waves. Combined with a handful of high-quality rights and an untouched island vibe, the Hinakos are ideal for surfers looking for long walls, serious barrels, and a chance to unplug.

Waves in the Hinako Islands

The Hinakos are known for their consistency, power, and lack of crowds. The surf scene here revolves around two standout waves—Asu and Bawa—but several lesser-known breaks fire when the conditions line up.

Asu

Asu is a long, world-class left-hander that breaks over coral reef, offering long walls with multiple barrel and turn sections. On the right swell, it runs for over 200 metres, providing plenty of opportunity for high-performance surfing. It handles a range of swells but really comes to life in the 4–8 ft range, with southwest swells and easterly winds offering ideal conditions. Asu is surfable on all tides, though mid to high is typically best for shape and safety.

Bawa

Located on the opposite side of the island chain, Bawa is a powerful right-hander and a completely different beast. It’s heavier, hollower, and far more exposed. When the swell is maxing and winds cooperate, Bawa turns on with serious force—drawing comparisons to waves like Sunset Beach or even Cloudbreak. This is a wave for confident surfers who are comfortable in serious surf and prepared to handle heavy water and unpredictable reef boils.

Secret Spots

With dozens of small islands and exposed reef passes, the Hinakos still hold a few secrets. Depending on wind, tide, and swell angle, there are occasional lefts and rights that come to life—especially when the more famous breaks are crowded or maxed out. Staying on a boat or with a camp that knows the area can unlock some of these lesser-surfed gems.

Surfing Conditions in the Hinako Islands

The best season for the Hinako Islands is April through October, when long-period south to southwest swells roll in from the Indian Ocean and collide with the reef at ideal angles. Asu is more protected, while Bawa is wide open to swell and wind, making early mornings and shoulder season days the best time to score it clean.

Winds tend to be light and variable in the mornings, with prevailing easterlies during the dry season offering perfect offshore conditions at Asu.

Surfing Ability in the Hinakos

The Hinakos are best suited to intermediate to advanced surfers, with most waves breaking over reef and requiring confidence on the takeoff.

• Intermediate Surfers: On smaller swells, Asu becomes far more approachable—long, clean walls with a friendly pace. It’s a great place to improve down-the-line surfing and start tackling soft reef setups.

• Advanced Surfers: When the swell builds, Asu offers long, powerful walls and deep barrels, while Bawa turns into a raw, heavy wave requiring serious commitment. Advanced surfers will find endless opportunity for high-performance turns, barrels, and big drops.

Surf Equipment for the Hinako Islands

Bring a small, versatile quiver if you plan to stay for a while:

• Performance Shortboard: Perfect for Asu’s long walls and carving sections.

• Step-Up Board: Recommended for bigger days at Bawa or when Asu hits the overhead-plus mark.

• Spare Gear: You’re remote—bring extra leashes, fins, and repair kits. There are no surf shops here.

Getting to the Hinako Islands

To reach Asu and the Hinakos:

1. Fly into Medan (KNO) – the main international gateway in North Sumatra.

2. Take a domestic flight to Gunung Sitoli (Nias Island).

3. From Nias, travel overland to Sirombu Harbour, then take a local boat or speedboat transfer to Asu Island.

Most surf camps and guesthouses will help coordinate transport from Gunung Sitoli, as logistics can vary with swell, tides, and boat availability.

Experience the Raw Beauty of the Hinako Islands

If you’re chasing long, reeling lefts, occasional heavy rights, and a quiet island pace far from the mainstream surf trail, Asu and the Hinako Islands should be on your radar. With powerful, uncrowded waves and a strong connection to nature, this region offers one of Indonesia’s last truly remote surf adventures—without sacrificing quality.
