Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
San Choi Wreck, situated in Malaysia's Maritime Zone near the Perhentian Islands, is a dive site born from purpose. Three fishing boats were deliberately scuttled in 2018, transforming them into an artificial reef.
Resting at a consistent depth of 18 m (59 ft), these structures offer an accessible wreck dive. A primary aim of this project was establishing new marine habitats, and the wrecks have successfully attracted substantial fish populations. Its relatively recent sinking means wreck structures are still undergoing natural colonization, creating a dynamic environment for observation.
As a focal point for marine activity, schools of fish frequently congregate so densely they can diminish ambient light around the structures. For certified divers, it represents an opportunity to witness the development of a man-made ecosystem, offering both historical context from its creation and a lively present-day encounter with abundant marine life.

Best Time to Dive
Planning a dive to San Choi Wreck should consider seasonal weather patterns, with optimal conditions typically aligning from June through September. This drier period features lower average wave heights, often around 0.2-0.3 m (0.7-1.0 ft), and lighter winds contribute to calmer seas. Rainfall is also minimal, ranging from 4.1 mm to 5.9 mm monthly, generally improving visibility. Air temperatures remain warm, averaging between 28°C and 28.5°C (82.6-83.7°F). Dive scores are consistently rated 'Excellent' during these months, signaling favorable underwater experiences. Beyond this peak window, conditions shift; from November to January, increased rainfall, higher waves, and stronger winds prevail, potentially leading to more challenging dive conditions. Operators often suspend tours during these wetter, choppier months due to reduced visibility and safety concerns. Visiting during the shoulder seasons like April-May or October might offer a compromise, though the consistency of excellent conditions lessens.

Dive Experience & Conditions
Descending onto the San Choi Wreck, divers are met with a lively artificial reef that immediately feels active. Three fishing boats make up the wrecks, sitting on a sandy bottom at a maximum depth of 18 m (59 ft). Water temperature, while not consistently reported with exact values, generally aligns with the tropical climate, typically ranging between 22-27°C (72-81°F) across the region. A notable feature of this site is the sheer volume of marine life; dense schools of fish can sometimes be so thick they create a noticeable reduction in ambient light. Visibility varies depending on conditions but can be quite clear during the optimal dive season. While currents are not consistently reported, local intel suggests generally manageable conditions, suitable for intermediate divers.
Dive Difficulty & Safety Guidelines
Diving the San Choi Wreck is considered suitable for intermediate certified divers due to its depth and the potential for dense fish aggregations. Since it's an artificial reef at a recreational depth, standard open water diving practices apply. Always dive with a buddy and conduct thorough pre-dive checks. Entry is exclusively by boat, requiring careful attention during descent and ascent, particularly with other divers present. While no specific hazards are consistently reported for the site itself, general precautions for wreck diving, such as avoiding penetration without proper training and equipment, are always advised. Adhering to local dive operator briefings and established safe diving limits helps ensure a secure experience.
