Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Constructed in 2013, Fred Morrow Reef provides a significant man-made habitat off Jacksonville's coast. Divers here encounter an extensive site, home to over 800 tons of strategically placed concrete culverts and pilings.
This deliberate construction has created a diverse underwater topography, forming numerous nooks and crannies essential for resident species. Functionally, the reef completes "The Triad," joining two older artificial reefs to form a notable ecological cluster. It lies approximately 20 nautical miles (37 km) southeast of the St. Johns River jetties, a considerable distance offshore.
At a maximum depth of 22 m (73 ft), the site remains easily accessible for most recreational divers. Its structure notably enhances local biodiversity, actively attracting a variety of marine organisms and offering opportunities for fishing.
Navigating the various concrete elements reveals different facets of a developing ecosystem, from the initial colonizing encrusting life to transient pelagic visitors. Divers can explore the varied channels and ledges formed by the culverts, finding potential shelter from currents in certain areas. This artificial landscape serves as a compelling example of successful marine habitat restoration.

Best Time to Dive
Planning a dive at Fred Morrow Reef is generally most comfortable from May through August, extending into November. These months typically offer "Good" dive scores due to more favorable surface conditions. During summer, average air temperatures range from 24°C (75°F) in May to a high of 27.5°C (82°F) in August. Wave heights are often lower in summer, particularly in July, averaging around 0.7 m (2.3 ft), which can lead to calmer boat rides and better visibility. While rain levels peak slightly in August and September, individual days can still offer excellent diving. November also presents "Good" conditions, with average air temperatures around 20°C (68°F) and lower rain incidence.

Dive Experience & Conditions
Descending onto Fred Morrow Reef, divers encounter a landscape shaped by deliberately placed concrete culverts and pilings. Maximum depth here typically reaches 22 m (73 ft), ensuring it remains within standard recreational limits. The water temperature isn't consistently reported, but seasonal variations are expected to mirror regional patterns. Visibility varies depending on oceanic conditions and recent weather, influenced by river outflow from the nearby St. Johns River. Expect currents to be present, varying in strength with tidal shifts and offshore weather. Navigating the artificial structures provides shelter and points of interest.
Dive Difficulty & Safety Guidelines
To safely explore Fred Morrow Reef, divers should hold at least an Open Water certification, with advanced training beneficial for navigating potential currents and deeper sections. As an artificial reef, sharp edges or unstable elements could be present, though the site is within recreational limits. Always maintain proper buoyancy control to avoid contact with the structures and minimize sediment disturbance. Given the varying conditions, a surface marker buoy (SMB) is recommended for all dives, especially due to potential boat traffic. Diving with a reliable buddy and conducting thorough pre-dive checks are essential; no specific hazards are reported, but general ocean diving precautions apply.
