Key Dive Site Facts
Dive Site Overview
Exploring Pecio Isurus reveals its history, dating back to January 18, 2003, when this fishing boat sank. Today, its structure lies leaning on a sandbed at an average depth of 40 meters (130 ft), making it a significant deep dive.
A remarkable state of preservation marks the wreck, which measures 22 meters (72 ft) in length with a 6-meter (20 ft) beam. Many of the original fittings and features remain identifiable, providing a tangible connection to its past life as a working vessel. Observing details like the propeller, visibly bent from impact with seafloor rocks, offers a testament to the vessel's final moments.
Divers navigating this maximum depth of 40 m (130 ft) will find a compelling underwater tableau, inviting thorough exploration of its exterior and accessible interior sections. Penetration into the wreck requires specialized training and appropriate safety protocols.
Given the significant depth, advanced gas mixtures like Nitrox or Trimix, or Rebreather systems, are recommended for managing gas consumption and decompression obligations effectively. Water temperatures typically range between 12-18°C (54-64°F) depending on the season, further emphasizing the need for suitable thermal protection.
Visibility around the wreck often provides clear views, but can vary with local currents and plankton activity.
Best Time to Dive
Year-round diving at Pecio Isurus is an option, however, summer months generally offer more favorable conditions compared to cooler seasons. June, July, and August typically present the most agreeable periods, indicated by 'Good' dive scores. Average air temperatures during these months range from 19.3°C (66.7°F) to 21.1°C (70°F), coupled with significantly reduced rainfall, often below 2.1 mm (0.08 in) monthly. Wave heights generally reach their lowest, averaging around 1.18 to 1.44 meters (3.9 to 4.7 ft), contributing to calmer surface conditions. Conversely, winter and early spring, from December to April, bring higher wave activity, increased wind speeds, and greater precipitation. Air temperatures can drop to around 11.2°C (52.2°F) in these cooler periods. Optimal planning for warmer, drier months enhances the overall dive experience at this deep wreck site.

Dive Experience & Conditions
Diving Pecio Isurus at an average depth of 40 meters (130 ft) immerses one in a somber, silent world where the wreck dominates the underwater landscape. An intact structure of a fishing boat provides a tangible sense of its former life. You can visually trace the path of impact that twisted its propeller against the rocky seabed. Visibility varies depending on oceanic currents and seasonal plankton blooms, though clear conditions can offer impressive views of the entire vessel. Water temperatures, not consistently reported for this specific site, typically reflect cooler Atlantic conditions off the Galician coast, varying seasonally. Reduced light penetration characterizes deep environments, lending an atmospheric quality to the exploration of the wreck's exterior. Prepare for cooler temperatures and potentially strong currents.
Dive Difficulty & Safety Guidelines
Navigating Pecio Isurus safely requires careful planning and appropriate certifications due to its maximum depth of 40 meters (130 ft). It's crucial that divers possess extensive experience in deep diving and are proficient with technical diving protocols. Using Nitrox, Trimix, or a Rebreather is highly recommended to manage gas consumption and decompression stops effectively, minimizing risks associated with nitrogen narcosis and oxygen toxicity at such depths. Always dive with a reliable buddy and ensure all equipment is in excellent working order. Proper ascent rates and safety stops are non-negotiable for a safe return to the surface from this demanding wreck site.
