Everything you need to know about this dive site.
Dive Site Overview
Navigating Daku Arch reveals a fascinating underwater topography, shaped by natural forces into a series of impressive rock formations and engaging swim-throughs. Divers enter an environment sculpted with at least two distinct passages, beginning with a comfortable, wide archway that allows for a smooth, unhurried entry.
This initial section transitions smoothly to a second passage. Progressing further, a subsequent opening narrows considerably, demanding precise buoyancy control and careful finning to maneuver efficiently through the more confined space. Beyond these immediate archways, the terrain shifts dramatically to an open sandy bottom, dotted generously with various coral clusters and isolated pinnacles.
These scattered formations provide crucial shelter and feeding grounds for a range of marine life. This diverse environment, blending structural complexity with expansive sandy areas, provides ample opportunities for varied marine interactions within the recreational depth limits.
Reaching a maximum depth of 16 m (52 ft), the interplay between shadowed rock structures and sunlit sandy stretches creates a dynamic dive profile, encouraging thorough exploration. Its unique geological features offer both exhilarating challenges and tranquil observation zones.

Best Time to Dive
Planning a dive to Daku Arch is generally most rewarding from March through October, when conditions typically favor clearer waters and calmer seas. During these months, the dive score averages 'Good' (7-8), reflecting more stable weather patterns. Rain levels are consistently lower, averaging around 5-8 mm, compared to the wetter periods of January-February and November-December, which see 11-14 mm of rain. Wave heights also tend to be minimal, often below 1 meter, creating comfortable boat entries and better visibility. Air temperatures throughout the year remain pleasantly warm, ranging from 26-28°C (79-82°F), with water temperatures typically remaining warm, usually ranging from 27-29°C (81-84°F).

Dive Experience & Conditions
Diving at Daku Arch offers a blend of structural exploration and open reef observation, making for a varied experience. Negotiating the distinct swim-throughs requires sound buoyancy skills, particularly within the narrower second passage where precision is key. Beyond the arch itself, a gently sloping reef extends onto a sandy bottom at depths up to 16 m (52 ft). Visibility at this site can range widely, often between 10-25 meters (33-82 ft), depending on recent weather and surge. Water movement typically involves light surge and motion, which can add a dynamic element to the experience, especially near the rock formations.
Dive Difficulty & Safety Guidelines
Ensuring a safe dive at Daku Arch begins with a thorough pre-dive briefing from a local professional. Given the presence of swim-throughs, advanced open water certification and strong buoyancy control are advisable, particularly for the more confined passages. Always dive with a buddy and maintain good awareness of your surroundings inside the archways. While generally a safe site, paying attention to variable currents and maintaining proper ascent rates are critical. It's also important to avoid contact with the delicate coral formations and rock structures to preserve this environment.
