Diving atCauseway Reef #26 (United States)
Causeway Reef #26 offers a distinct underwater experience in the Gulf of Mexico, off Lee County, Florida. Unlike natural formations, this site began as deployed remnants of old causeway infrastructure – primarily piling cutoffs, road bed, and guardrails. Now, these submerged structures have been given a second life, forming an artificial reef that attracts diverse marine organisms. It serves as a vital habitat within a maximum depth of 8.5 m (28 ft).
Current morning readings from Causeway Reef #26 indicate an air temperature of 28.5°C. Surface wave heights are averaging around 0.2 m at this time. These local measurements provide a baseline for your daily dive planning.
Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Causeway Reef #26 presents an entirely artificial underwater topography, meticulously sculpted from discarded causeway materials that now foster a thriving ecosystem. At a maximum depth of 8.5 m (28 ft), the site integrates diverse structures including piling cutoffs, substantial sections of road bed, robust pile caps, and guardrails.
Initial deployment of these repurposed elements occurred in February 2006, with additional components added as recently as November 2007, cumulatively crafting a complex and varied underwater landscape. Spread across the area, individual plots, designated from SC1 to SC29, each showcase unique formations derived from the original construction components.
Divers navigating these sub-structures can systematically explore distinct features, such as the expansive steel road bed sections and numerous pilings that ascend from the seafloor, providing vertical relief. Arrangement of these varied materials naturally creates an abundance of nooks, sheltered ledges, and protective overhangs, encouraging thorough exploration and serving as micro-habitats.
An accessible dive profile, well within recreational limits, facilitates extended bottom times, offering ample opportunity to observe the marine life actively colonizing these repurposed structures. Causeway Reef #26 represents a notable and successful effort to transform retired infrastructure into valuable, flourishing marine habitat.

Best Time to Dive
Choosing the optimal time to dive Causeway Reef #26 often involves balancing air temperatures with calmer sea conditions. Dive scores frequently register as 'Good' throughout much of the year, with notable 'Excellent' periods occurring in May and July. During these months, average air temperatures are particularly warm, reaching around 26°C (79°F) in May and peaking at 28°C (82°F) in July, which enhances the surface interval comfort. Rainfall also tends to be higher in summer months, with June averaging 8.2 mm (0.32 in) and August around 6.98 mm (0.27 in), which might affect surface visibility slightly. Conversely, the cooler, drier months from January to April still offer 'Good' dive conditions, despite lower air temperatures ranging from 17°C (63°F) in January to 23.5°C (74°F) in April. Wave heights are generally lower during the warmer months, averaging around 0.3 to 0.6 m (1.0-2.0 ft), which typically translates to smoother boat rides and potentially better underwater visibility. Prioritizing the spring and summer for potentially calmer conditions and warmer air is often preferred by many divers.

Dive Experience & Conditions
Current dynamics at Causeway Reef #26 are not consistently reported, but being a relatively shallow site in the Gulf of Mexico, divers should anticipate conditions that can vary based on local tides and weather patterns. While some days may bring gentle movements, stronger currents are possible, requiring divers to remain aware of their positioning, particularly around the artificial structures. Visibility at this reef tends to vary, influenced by factors like recent rainfall, sediment suspension, and offshore conditions. Recreational depths mean light penetration is generally good when visibility allows. Water temperatures are not specifically available, but typically reflect regional Gulf seasonal averages, which usually remain comfortable for diving for much of the year. This site provides an accessible dive experience for various certification levels, though awareness of potential current changes enhances safety and enjoyment.
Dive Difficulty & Safety Guidelines
Navigating an artificial reef site like Causeway Reef #26 requires attention to specific safety considerations. The presence of numerous man-made structures, including piling cutoffs, guardrails, and steel road bed, means divers should exercise precise buoyancy control to avoid unintentional contact or entanglement. These structures, while forming valuable habitats, can present irregular surfaces and potential snags. Always maintain situational awareness, especially when exploring closer to the various components of the reef. Given the site's maximum depth of 8.5 m (28 ft), ascending slowly and performing safety stops remains a standard practice, even in shallower waters. Dive within your certification limits and consider carrying a cutting tool as a precaution when diving around submerged man-made objects. Proper planning and gear checks before entry are crucial for a safe and enjoyable dive.
