Dive Site Overview
Cambodia's dive landscape presents a compelling mix of underwater terrains, catering to a range of experience levels. These aquatic environments encompass everything from extensive shallow coral gardens, teeming with juvenile life, to more challenging wall dives that drop away into the deeper blue.
Many sites frequently feature broad sandy expanses, which are punctuated by isolated coral bommies, creating distinct ecosystems where smaller creatures find shelter. Depths encountered can range from a very accessible 2 m / 7 ft over some of the vibrant coral formations, extending to over 30 m / 100 ft on specific deeper walls, such as those found at locations like The Drop Off.
Notably, Condor Reef exhibits an unusual underwater architecture, where enormous rectangular rock formations create a series of natural terraces, mini-walls, and even swim-through archways, providing a fascinating exploratory experience. Beyond natural formations, certain dive sites hold historical intrigue, with scattered remnants of ancient Chinese junks and, cautiously, reports of undetonated bombshells.
Water temperatures are a constant, remaining comfortably warm, typically between 28-30°C / 82-86°F, which makes exposure suit choice simple. This consistency allows divers to focus on the diverse topography and the array of marine life it shelters.
Best Time to Dive
Planning your Cambodian dive trip around the seasons significantly impacts the underwater experience, particularly concerning visibility. While clarity typically varies from 5 to 35 meters, often averaging around 10 meters depending on the specific site and prevailing conditions, understanding seasonal shifts is key. The northeast monsoon season, which runs from December through April, consistently emerges as the most favorable window for diving. These months are characterized by sunny, dry weather and notably minimal rainfall, factors that collectively contribute to maintaining excellent underwater visibility and calmer sea states. During this peak season, air temperatures are comfortably warm, generally settling between 27-29°C / 81-84°F, making surface intervals pleasant. Furthermore, the dry season significantly increases the probability of encountering larger pelagic species; whale shark sightings are more frequent, especially observed around December and again in May, making these periods particularly appealing for those hoping for a truly memorable encounter.

Dive Experience & Conditions
Current dynamics are a notable feature of many Cambodian dive sites, often leading to exhilarating drift dives. Locations like Cobia Point and The Drop Off frequently experience currents, making them well-suited for divers comfortable with drift techniques. The water temperature remains consistently warm, typically between 28-30°C / 82-86°F year-round, eliminating the need for thick wetsuits. Conditions can vary, with some sites being accessible to beginners, while others, like Eagle-ray Alley, are recommended for more experienced divers due to potential currents or exposed conditions. Wave heights are generally moderate, though conditions can become a bit choppier during certain months, potentially making boat rides less smooth.
Dive Difficulty & Safety Guidelines
While diving in Cambodia, specific safety considerations include the presence of undetonated bombshells at sites like Condor Reef, requiring adherence to guide instructions. Varying current strengths, which can lead to drift dives, necessitate appropriate experience and attention to dive planning. Divers should research operators to ensure quality and safety standards are met, as the caliber of services can differ. Always ensure your equipment is in good working order and that you are diving within your certification and experience limits, especially on sites recommended for more advanced divers.

Marine Life at Last Chance
The immediate visual impact at many sites is often an 'explosion' of color from diverse juvenile fish species finding refuge among staghorn corals. Divers frequently encounter schools of batfish, trevally, and barracuda over sandy expanses. Macro enthusiasts will appreciate spotting various nudibranchs and marine worms among the corals. Rays are a common sight, from electric blue-spotted stingrays to larger eagle rays, with increased activity during night dives. Moray eels, including white-eyed and hexagonal varieties, are routinely observed, along with octopuses, scorpionfish, and crustaceans. Lucky divers may also spot black-tip reef sharks, particularly at cleaning stations, and seasonal visits from whale sharks.
