Best Time to Dive
Prime diving for Bajo del Diablo typically runs from December to April, offering generally calmer conditions for this pelagic hotspot. During these months, the Pacific experiences less rain, with averages ranging from a low of 0.6 mm in January to 4.1 mm in December and April. This dry period correlates with air temperatures consistently around 25.5-27.3°C / 78-81°F, enhancing overall comfort on the surface. While external data indicates liveaboard trips extend into May, and dive scores are "Good" for most of the year (July-September, November, December), divers should be aware that wave heights tend to increase from May through November, potentially impacting surface conditions and overall accessibility. October and May-June are rated "Moderate" for diving, experiencing higher rainfall and waves, which could affect visibility and current strength.

Dive Experience & Conditions
Strong currents often dictate the start of a dive at Bajo del Diablo, making the descent particularly demanding, especially in shallower areas. Site topography features a submerged pinnacle, with its highest point about 7-8 meters deep, making it a critical area for navigation and safety. From this shallow pinnacle, the terrain slopes dramatically, forming deep valleys of white sand between rock ridges and outer walls that extend beyond 30 meters. Visibility at the site is generally very good, ranging from 15-30 m / 50-100 ft, although it can vary with conditions. Water temperatures are comfortably warm, typically between 22-26°C / 72-79°F during winter months and 24-28°C / 75-82°F in summer. While some reports mention mild currents, divers should primarily prepare for very strong, dynamic water movement and moderate surge, especially near the surface and along the cleaning stations. This site is recommended for intermediate to advanced divers due to these challenging conditions.
Dive Difficulty & Safety Guidelines
Preparing for a dive at Bajo del Diablo involves several critical considerations to ensure a safe and rewarding experience. Divers should be comfortable with strong, often unpredictable currents, and proficient in drift diving techniques. Back and forth movement in shallower areas, particularly near cleaning stations, can be exhausting. Always dive with a qualified guide familiar with local conditions and consider bringing an SMB for surface signaling. Permits are required for diving in this biological preserve and can be obtained through local dive shops, ensuring compliance with protection regulations. An average dive time of 50 minutes is typical, but current strength can influence gas consumption and bottom time significantly. Prioritize current awareness and clear communication within your dive group.
