Dive Site Overview
Structured from 19 steel and concrete radio towers, the Concrete Pyramids artificial reef system is primarily situated at a depth of approximately 14 m (45 ft). These robust structures rise about 6 m (20 ft) from the sandy bottom, creating an intricate landscape for divers to explore.
The site is a collection of large and smaller concrete blocks, intentionally placed to cultivate a rich ecosystem. Originally sunk in 1988, the pyramids are now encircled by smaller reef modules, contributing to a vibrant underwater city. Nearby, other artificial reef projects, including the Miss Patricia/Miss Karline wrecks and a 'Rock Pile,' further enhance the local underwater topography, offering varied exploration opportunities within the vicinity.
This configuration provides expansive areas for juvenile fish to grow and breed, supporting local marine populations.
Best Time to Dive
Diving conditions at the Concrete Pyramids vary throughout the year, with a clear distinction between favorable and moderate periods. Optimal conditions typically occur from May through September, when dive scores consistently rank as 'Good.' During these months, average air temperatures are warmer, ranging from 24.6°C (76°F) to 29.3°C (85°F), contributing to a more comfortable surface interval. Rain levels also tend to be manageable during this peak season. Conversely, the months from October through April generally present 'Moderate' dive scores. Winds are often stronger, reaching average speeds of 31.3 km/h (19.4 mph) to 37.7 km/h (23.4 mph), potentially leading to higher wave heights averaging 1.17 m (3.8 ft) to 1.42 m (4.7 ft). Such conditions can affect visibility and surface comfort for divers.

Dive Experience & Conditions
Descending upon the Concrete Pyramids, divers will find themselves exploring an artificial reef resting at around 14 m (45 ft). Individual structures create a dramatic underwater profile, rising about 6 m (20 ft) from the seafloor. Visibility can vary, but clear conditions often allow for a wide view of the formations and the activity around them. A unique aspect of navigating here involves reported magnetic interference from the original radio antennas, which can impact compass readings. This makes the location a popular spot for navigational trainee divers to hone their skills in challenging conditions. Currents are generally mild to moderate, allowing for thorough exploration of the concrete blocks and their numerous inhabitants. The atmosphere here feels established, like a purpose-built marine haven.
Dive Difficulty & Safety Guidelines
When planning a dive at the Concrete Pyramids, divers should be particularly aware of potential magnetic interference. The site's original radio antennas are still capable of affecting compass navigation, necessitating careful attention to alternative directional cues or advanced navigational skills. As an artificial reef, these structures feature many crevices and ledges; divers should maintain proper buoyancy control to avoid entanglement or accidental contact. This site is suitable for Open Water Divers due to its relatively shallow depth. Always prioritize your dive plan, monitor air consumption, and ascend safely. Given the site's characteristics, a surface marker buoy is recommended for easy location by the boat crew.

Marine Life at Concrete Pyramids
Observing the Concrete Pyramids reveals how swiftly marine ecosystems can reclaim and transform artificial structures. The site acts as a nursery, with many juvenile fish establishing themselves among the protective crevices of the concrete blocks. Various reef fish species, attracted by the shelter and food sources, are a common sight darting between the formations. Divers often notice schools of baitfish, which in turn draw larger predators to the area. This vibrant artificial habitat supports a robust population, underscoring its success in bolstering local biodiversity.

What is the typical depth range for diving here?
Generally found at recreational depths around 14 meters, the site allows for comfortable exploration. Structures rise approximately 6 meters from the seafloor, creating varied vertical relief.
Is this site suitable for beginner divers?
Yes, the Concrete Pyramids are suitable for Open Water Divers due to their relatively shallow maximum depth of about 14 meters. Good buoyancy control is always beneficial for exploring artificial reef structures.
What makes navigating this site unique?
Original radio tower antennas at the site can interfere with dive compasses. This characteristic makes it a popular spot for navigational training, offering divers a chance to practice orientation without relying solely on a compass.
What kind of marine life can be observed?
As a thriving artificial reef, the Concrete Pyramids provide shelter and breeding grounds for a variety of reef fish. You'll often see juvenile fish, schools of smaller fish, and other marine life utilizing the complex structures for habitat.
What is the best time of year to dive the Concrete Pyramids?
The best time for diving is typically from May through September, when climate data indicates 'Good' dive scores, warmer air temperatures, and generally lower wave heights. Other months may experience higher winds and waves, making conditions more moderate.
