Key Dive Site Facts
Dive Site Overview
Among the earliest established sanctuaries in Moalboal, Ronda Bay Marine Sanctuary, also known as Saavedra Marine Sanctuary, holds a significant place in the region's dive history. The site presents a distinctive reef and wall dive profile, beginning with a vibrant coral slope.
This slope gently descends before plunging into a steep wall at approximately 18 m (59 ft), which then drops further to a maximum depth of 55 m (180 ft). Along its vertical face, divers can observe an impressive collection of giant fan corals, sometimes numbering around a hundred, creating a visually rich environment.
Exploring the wall's crevices and rocky outcrops reveals a hidden world of macro life. Drift diving is a common approach here, allowing divers to effortlessly traverse sections of this extensive reef system. Its established status ensures a protected habitat, fostering diverse marine populations.
Best Time to Dive
Optimizing a visit to Ronda Bay Marine Sanctuary hinges on understanding the regional weather patterns. The months of April through June, along with August through November, consistently register as 'Excellent' for diving. During these periods, average wave heights are minimal, often below 0.2 meters, and wind speeds are generally lower, contributing to calmer surface conditions. Rainfall is also notably less during April and May, averaging around 2.8 to 4.7 mm, which typically corresponds to better visibility. Air temperatures remain consistently warm throughout the year, ranging from 26°C to 28°C (79-82°F), making surface intervals comfortable. Although water temperatures aren't consistently reported, the tropical climate suggests warm conditions aligning with air temperatures.

Dive Experience & Conditions
Beginning a dive here often involves a gentle descent over the coral-covered slope, which soon gives way to the sanctuary's signature steep wall. This transition provides a dynamic entry into the site's deeper sections. Water temperatures typically remain warm, consistent with tropical environments, ensuring comfortable diving without heavy thermal protection. Visibility often allows for impressive panoramic views of the expansive wall, though it varies depending on recent weather and currents. While specific current reports for Ronda Bay aren't always consistent, the site is known for drift diving, indicating that currents can be a factor, particularly along the wall. Divers should be prepared for potential moderate water movement, which can enhance the experience of covering more ground along the reef.
Dive Difficulty & Safety Guidelines
Diving within a marine sanctuary like Ronda Bay requires a mindful approach to ensure both diver safety and ecosystem preservation. Maintaining excellent buoyancy control is crucial, especially when navigating the steep wall, to avoid accidental contact with delicate corals and other marine life. Given the potential for currents, particularly during drift dives, divers should carry an audible signaling device and a surface marker buoy (SMB) for safe ascent and surface recovery. Always dive within your certification limits; the wall drops to depths beyond recreational boundaries. Respecting the sanctuary's protected status means refraining from touching or collecting any marine organisms or disturbing the natural environment. These practices help sustain the site for future exploration.
