Key Dive Site Facts
Dive Site Overview
Dramatic underwater landscapes characterize Racha Noi Island, particularly reminiscent of the Similan Islands with massive granite boulders piled on the seabed. Surrounding waters are notably deeper, with sandy slopes descending to 70 m (230 ft) in places, increasing the likelihood of encountering pelagic species from the open ocean.
Dive sites here cater to all certification levels. Banana Bay, located on the east coast, features gentle sandy slopes, starting at around 3 meters and descending to about 25 meters.
These depths, roughly 10 to 82 feet, with scattered corals, make it suitable for entry-level training and relaxed dives. On the west side, Marina Bay presents a rocky environment with numerous swim-throughs and depths often reaching 30 meters.
Further south, Racha Noi Bay offers a mix of branching coral formations in shallower waters and piled rocks in deeper sections, with a maximum depth of around 25 meters. South Tip is reserved for advanced divers, often plunging beyond 30 meters into areas where larger marine life is more frequently observed. This site can experience strong currents, adding to its appeal for experienced divers.
Best Time to Dive
Racha Noi offers distinct experiences depending on the season, allowing year-round trips from Phuket. From November to April, conditions are generally optimal with good dive scores (7-8) and typically lower rainfall, averaging 0.9-5.2 mm. Air temperatures during this period remain comfortable, ranging from approximately 27.7°C (81.9°F) in January to 29.0°C (84.2°F) in April. Dry season conditions favor the west side, north tip, and South Tip, where divers can best appreciate the dramatic topography and potentially spot larger pelagics. Between May and October, the 'low season' brings moderate dive scores (6-7) and higher rainfall, with averages peaking around 10.3 mm in November. During these months, prevailing westerly winds often make eastern bays like Banana Bay the preferred, calmer dive spots.

Dive Experience & Conditions
Entering the waters around Racha Noi, conditions vary from serene to challenging. Visibility commonly ranges from 10-25 m (33-82 ft), influenced by currents and recent weather. Currents are generally weak to moderate in the sheltered bays but can be significant, particularly around the northern, western, and southern tips, as well as in deeper sections. These stronger currents often accompany the presence of large pelagic animals. Topography shifts from pure white sandy bottoms and gentle slopes in protected bays to impressive granite boulders and rocky formations with intricate swim-throughs at more exposed sites. While specific water temperature data isn't consistently reported in our system, the tropical climate ensures generally warm diving conditions.
Dive Difficulty & Safety Guidelines
For an enjoyable dive at Racha Noi, divers should plan according to their certification level and local conditions. Always monitor current strength, especially when approaching exposed areas like the South Tip, where drifts can be strong. Deep dives beyond 30 meters, often pushing past 100 feet, are common at specific sites, requiring appropriate advanced training and gas planning. Maintain excellent buoyancy control, particularly when navigating the boulder formations and swim-throughs to protect the delicate marine environment. Novice divers should stick to the calmer, shallower bays, while advanced divers can explore the deeper, more challenging sites. Listen carefully to your dive guide's briefing regarding entry and exit points, as conditions can change rapidly.
