Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Punta Sur offers a multi-level experience, revealing a dive site defined by deep, intricate structures excellent for advanced divers. Two distinct sections comprise the site, with a diver's air consumption often dictating whether both can be thoroughly explored during a single descent.
On the southernmost part, 'The Cathedral' stands as a prominent feature, a large chamber with expansive passages. Divers explore these passages at depths around 30 m (100 ft), navigating through impressive reef formations. Further on, the famed 'Devil's Throat' presents a long, winding cavern swim-through, a signature canyon experience.
This entry opens at approximately 27 meters and descends progressively, narrowing as it winds deeper through the reef, reaching depths up to 42 meters. Navigating this cavern requires comfort in enclosed spaces and a reliable dive light.
The interplay of deep walls, complex reef structures, and variable currents creates a dynamic environment, changing significantly with depth and demanding careful attention to buoyancy and air management throughout the dive profile.

Current conditions near Punta Sur show 28° air, 29° sea temperature, 1.0 m waves, and 25 km/h wind. Forecast data is refreshed regularly to ensure accuracy.
Best Time to Dive
For optimal visibility and comfortable conditions, planning a dive at Punta Sur is generally favorable during the months of May, July, August, and September, which often report better dive scores. During these periods, average air temperatures range between 28°C (82°F) and 29°C (84°F), contributing to pleasant topside conditions. Rain averages are notably lower in May, at 0.74 mm, and remain relatively low through July and August. While wave heights can vary, they tend to be calmer, particularly in August, averaging around 0.8 meters. These conditions can enhance the underwater experience, potentially leading to clearer sightlines into the deep passages and along the walls of this challenging site.

Dive Experience & Conditions
Current dynamics largely define the experience at Punta Sur; currents are typically strong and often necessitate a drift diving approach. These powerful midwater currents, combined with the site's southern location and exposure to prevailing trade winds, can make topside conditions quite rough. This environment demands that divers possess advanced skills, particularly in rapid and problem-free descents, to avoid missing the intended dive site. Depths here range from 27 m (90 ft) down to 40 m (130 ft) and deeper in specific sections like the Devil's Throat. Given the deep profiles and potential for extended bottom times within recreational limits, meticulous air management is crucial. The water is consistently saltwater, though specific temperature data is not consistently reported for this location.
Dive Difficulty & Safety Guidelines
Diving Punta Sur requires an advanced skill level, primarily due to the site's inherent hazards. Strong prevailing currents and significant depths, commonly reaching 40 m (130 ft) in many areas, demand proficient deep diving and drift diving experience. Divers must be able to descend quickly and control their buoyancy effectively upon reaching the site. Within the Devil's Throat, depths push even further, up to 42 meters, and this long, winding, and narrowing cavern necessitates comfort in confined, dark spaces. Carrying a dive light is essential here. Without proper training, such as PADI Advanced Open Water Diver and PADI Deep Diver certifications, attempting this dive is not recommended. Careful planning and briefing with a local dive professional familiar with current conditions are paramount.
