Key Dive Site Facts
Dive Site Overview
Descending upon the Pecio Cordero Gonzalez offers a compelling journey back to 1975, the year this vessel met its fate through collision. Approximately 28 meters (92 ft) long, the substantial metal wreck now rests upright on a bed of very fine sand near Isla de Ons' eastern face.
Divers encounter a largely intact main hull, yet numerous openings and access points invite close inspection. Structural breaks create natural swim-throughs and sheltered nooks, providing engaging points of interest throughout a dive. Beyond being a static piece of history, the Cordero Gonzalez is an evolving habitat, with resilient surfaces colonized by vibrant marine growth.
Exploring its entirety is manageable; the area is compact enough for thorough investigation during a single dive. Composed of very fine sand, the surrounding seafloor requires precise buoyancy control to avoid disturbing visibility.
At a maximum depth of 27 m (89 ft), the site positions itself as an advanced dive, demanding experience in managing depth and potential thermal considerations in Galicia's often cooler waters. Its detailed structure promises an engaging experience for those prepared.
Best Time to Dive
Optimal diving conditions at Pecio Cordero Gonzalez often align with periods of calmer seas and reduced rainfall, which typically enhance underwater visibility. While water temperature isn't consistently reported across the year, specific autumn reports indicate around 13°C (55°F). Air temperatures are most favorable from June to September, ranging from 18-21°C (64-70°F), correlating with lower wave heights, averaging 1.3-1.9 m (4.3-6.2 ft), and minimal rainfall, around 0.6-4.4 mm. Conversely, winter months present significantly less favorable conditions with higher wave heights, up to 3.8 m (12.5 ft), increased wind speeds, and substantial rainfall, making dive scores 'Unsafe' or 'Poor'. Spring and late autumn see moderate conditions; however, historical reports have noted visibility as low as 5 m (16 ft) in October. Therefore, planning dives between June and September is generally recommended for the best chance of clear sightlines and more comfortable topside weather, although local conditions can always vary.

Dive Experience & Conditions
Reaching 27 m (89 ft), the Pecio Cordero Gonzalez's depth profile is a primary factor classifying it as an advanced dive. Such depths necessitate careful bottom time management and appropriate air consumption planning. Lying on a bed of extremely fine sand, the wreck demands excellent buoyancy control; disturbance can rapidly reduce visibility. While specific current reports vary, one October dive noted no significant currents. Conditions aren't consistently challenging, though divers should always be prepared for potential changes, especially given its coastal location. Numerous points of interest arise from the metal wreck's structural integrity, including many hiding spots for marine life. However, exploring internal spaces demands advanced wreck diving skills and specialized training.
Dive Difficulty & Safety Guidelines
Approaching the Pecio Cordero Gonzalez demands a solid understanding of advanced diving protocols. This site's inherent depth requires divers to be properly certified and experienced in deep diving. Buoyancy control is paramount due to the fine, silty sand surrounding the wreck; accidental contact can drastically reduce visibility for everyone. While currents were not reported during one dive, conditions can change, so it's advisable to assess local currents before entry. Penetration of the wreck is not generally recommended without specific wreck diving training and appropriate equipment, as the structural integrity and internal layout can pose entanglement and disorientation risks. Always dive with a reliable buddy and carry appropriate safety gear, including a dive computer and surface marker buoy. A thorough pre-dive briefing from a local guide is crucial to understand site-specific hazards and current conditions.
