Key Dive Site Facts
Dive Site Overview
Chimo's underwater landscape is a product of millennia, featuring dramatic rock formations. Known locally as 'Las Iglesias' due to their cathedral-like appearance, these impressive pillars emerge directly from the seafloor.
An expansive dive area spans over 400 meters (1,300 feet), revealing an intricate system of pinnacles and extensive reefs. Divers navigating these structures encounter a significant depth range, starting around 9 m (30 ft) in shallower zones and plunging beyond 61 m (200 ft) at the formations' bases. Its considerable distance from human development helps preserve a pristine environment, making it a compelling destination for experienced divers seeking unspoiled conditions.
Access typically involves a boat journey lasting 60 to 90 minutes, departing from locations such as Punta de Mita or Marina Vallarta. While travel time extends the trip, it ensures a dive experience far removed from typical shore entries, highlighting large, vibrant schools of fish and unique coral species uncommon in other parts of the region. Deeper exploration here promises encounters with marine life thriving in its undisturbed habitat.
Best Time to Dive
Seasonality plays a significant role in optimizing a Chimo dive experience, with consistently good dive scores year-round. A dry season, roughly from November to May, typically offers the most stable conditions with minimal rainfall, averaging less than 1 mm (0.04 inches) per month. During this period, air temperatures generally range from 22.5-26.1°C (72.5-79.0°F). Wetter months, from June to October, see increased rainfall, up to 7 mm (0.28 inches) monthly, and warmer average air temperatures climbing to 28.3°C (82.9°F). Water temperatures aren't consistently reported, though the regional climate suggests warm conditions throughout the year. For comfort, drier, slightly cooler air months might be preferred by some. Wave heights tend to stay within a manageable range of 1.08-1.42 m (3.5-4.7 ft) throughout the year, with winds typically between 9-13 km/h (5.6-8 mph).

Dive Experience & Conditions
Approaching Chimo requires divers to possess an Advanced Open Water certification or a minimum of 25 logged dives due to the site's challenging conditions. Strong and unpredictable currents often characterize dive conditions, demanding excellent buoyancy control and navigational skills. Depths range considerably, from approximately 9 m (30 ft) at the reef crest to well over 61 m (200 ft) at the base of the pinnacles. Diverse rock formations and extensive reef systems provide a varied underwater topography to explore. Divers should prepare for potential long boat rides to reach this remote location. Demanding conditions contribute to the site's appeal, preserving an environment where large pelagics and abundant fish schools thrive.
Dive Difficulty & Safety Guidelines
Diving at Chimo necessitates adherence to advanced safety protocols. Given the potential for challenging currents and significant depths, divers must be self-sufficient and comfortable in dynamic underwater environments. It's crucial to dive within certification limits and not exceed recommended maximum depths. Maintain excellent situational awareness, especially concerning your dive buddy and group, as currents can cause separation. Always plan your dive thoroughly, including gas management, and consider carrying a surface marker buoy (SMB) for safety. Professional dive operators for Chimo trips typically manage small groups, often with a maximum of 8 divers, ensuring focused guidance and supervision, which is advisable for this site. No specific natural hazards are reported beyond the prevailing currents and depth profiles.
