Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Descend into the waters surrounding CSX Rubble and discover an evolving artificial reef environment. This site, comprising concrete bridge sections and potentially larger structures like steel barges, rests at depths typically ranging from 12 m (40 ft) to around 27 m (90 ft).
Divers encounter a rugged topography, where the varied rubble forms intricate nooks and crannies for exploration. The structures are quickly becoming encrusted with growth, transforming into vibrant habitats for local marine species. Visibility here can fluctuate significantly throughout the year.
During cooler winter months, from November to April, conditions are often clearest, reaching 12-15 m (40-50 ft). However, warmer summer waters, from May to October, may reduce visibility to 3 m (10 ft) or less due to increased algae growth.
Surface water temperatures range from a cooler 10-15°C (low-50s°F) in winter to a warmer 29-30°C (mid-80s°F) in summer. Below the thermocline, water can be 5-8°C (10-15°F) cooler, but never drops below 10°C (50°F), especially noticeable at deeper sections.
Advanced open water divers comfortable with potential limited visibility and navigating structural environments will find this site rewarding.

Best Time to Dive
Optimizing visibility is key when planning a dive to CSX Rubble, making the cooler winter months the preferred period. From November to April, surface visibility frequently extends to 12-15 meters, providing clearer views of the reef structures. During these months, average air temperatures range from 13.5°C (56°F) in January to 21°C (70°F) in April, typically feeling moderate on the surface. Rainfall tends to be lower and more consistent, averaging between 2.65 mm (0.10 in) and 4.58 mm (0.18 in) monthly. As temperatures rise from May to October, reaching average air temperatures of 24.5°C (76°F) to 29°C (84°F), warmer surface waters stimulate algal blooms, which can decrease visibility to 3 meters or less. While the warmer water might be comfortable, the reduced clarity significantly impacts the dive experience. Dive scores generally rate "Good" from May to September, primarily due to calmer seas and higher air temperatures, but "Moderate" during other months, often influenced by increased wave heights and cooler conditions.

Dive Experience & Conditions
A descent at CSX Rubble immediately reveals a collection of artificial structures, primarily concrete bridge sections that form the core of this reef. As divers drop through the water column, they encounter the varied relief of these components, which are positioned between recreational depths and deeper sections. The maximum depth for some barge or wreck components can reach about 27 m (90 ft). General rubble sections might be shallower, around 12 meters. Expect thermoclines, especially during summer, where temperatures can drop noticeably at 21-24 meters and deeper, reaching depths of 30 meters. Surface water temperatures vary from 10-15°C (low-50s°F) in winter to 29-30°C (mid-80s°F) in summer. Divers should be proficient in buoyancy control to avoid stirring up sediment, which can quickly reduce visibility on these structures. Current conditions are not consistently reported but can vary, requiring divers to remain attentive to their surroundings.
Dive Difficulty & Safety Guidelines
Diving at CSX Rubble requires a proactive approach to safety due to its nature as an artificial reef and shared water space. Entanglement is a significant concern; fishing is popular in the area, meaning old trotlines and monofilament line are often present. Always carry a dive knife to address potential snags from submerged brush, trees, and discarded fishing gear. Being a popular boating area, remaining close to your dive flag is crucial. Boaters must stay at least 30 meters clear, observing the 100-foot rule from a displayed red and white dive flag. Utilize the buddy system, and never dive beyond the capabilities of the least experienced diver in the group. If exploring any cave or karst features that might be nearby, ensure you possess appropriate training and certification. Avoid designated boat mooring, docking, or harbor areas, as these are restricted for diving.

Marine Life at CSX Rubble
The artificial structures of CSX Rubble provide a foundational habitat for developing marine ecosystems. As you explore the concrete bridge sections and potential barge components, you'll observe fish species adapting to these newly formed reefs. While specific detailed reports are limited, artificial reefs generally attract various species. Expect to encounter common coastal fish that seek shelter and foraging opportunities within the rubble, such as snook and sheepshead. Manatees and dolphins are sometimes seen in the broader area, though direct sightings at the rubble site itself are not consistently reported. The site's evolving nature means that, over time, a diverse array of invertebrates and smaller reef fish will colonize the surfaces.
