Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Beyond typical reef exploration, Rhode Island offers a dive experience steeped in American maritime history. Its expansive 400 miles of shoreline hide a significant collection of shallow and deep water wrecks, encompassing tugs, submarines, steamships, freighters, and schooners.
These underwater artifacts, alongside remains of Revolutionary War and World War II forts, bring the state's storied past to life for divers. Sites like Fort Wetherill State Park in Jamestown provide accessible shore entries, where divers can explore remnants of a WWII defense battery and former anti-submarine net anchor points within its protected coves. Divers will find diverse underwater terrains including expansive eelgrass beds, soft sandy bottoms, and dramatic anemone-covered cliff walls.
Endless rock formations also present numerous nooks and crannies to explore. While surface conditions can vary seasonally, the historical density of these sites ensures every dive is a journey through time.
The dynamic environment, influenced by the Gulf Stream, occasionally introduces unique temporary tropical marine life.

Best Time to Dive
Prioritizing optimal visibility for your dive planning is essential in Rhode Island's dynamic waters. Spring and fall typically present the best visibility conditions, even if the water temperatures are cooler. During these shoulder seasons, average air temperatures range from 5°C (41°F) in March to 19°C (66°F) in September, with rainfall varying between 4.03 mm (April) and 5.23 mm (May). Seas are generally calmest and warmest during the summer months, specifically June through August, where average air temperatures reach 19.5-23.5°C (67-74°F). Water temperatures during summer can reach into the 20s°C (70s°F), making it suitable for wetsuit diving. This period also generally sees lower wave heights, averaging 0.9-1.0 m (3.0-3.3 ft), and reduced wind speeds, typically around 17.7-18.2 km/h (11.0-11.3 mph), contributing to a "Good" dive score. While the warmer Gulf Stream influences conditions from May through October, divers planning trips outside these months should expect colder water and consider drysuit use for comfort.

Dive Experience & Conditions
Rhode Island's diverse dive sites cater to a wide range of certifications, offering depths from shallow coastal explorations to deeper wreck penetrations. Many shore dives, like those at Fort Wetherill, remain within recreational depth limits. Deeper opportunities exist on significant wreck sites such as the U-853 in Rhode Island Sound, which can extend to 36 m (120 ft) or more, depending on the specific section of the wreck. Water temperatures fluctuate considerably with the seasons; summer sees temperatures in the 20s°C (70s°F), dropping significantly by 5-10°C (10-20°F) as winter approaches. Visibility, while occasionally good in spring and fall, is not consistently reported and can be variable. Divers should be prepared for potential currents, particularly on ocean sites, and adapt their dive plans accordingly. Cold water diving principles are often applicable outside of peak summer.
Dive Difficulty & Safety Guidelines
Navigating Rhode Island's underwater environment demands a keen awareness of local conditions, particularly regarding water temperature and currents. Even during warmer months, thermoclines can be present, requiring proper thermal protection. Visibility, while sometimes excellent, can change rapidly due to tidal movements or weather, making effective communication and navigation skills essential. Dive sites, especially historical wrecks, may present entanglement hazards, emphasizing the importance of careful buoyancy control and carrying a cutting tool. Divers exploring deeper wrecks must be proficient in advanced techniques. Always confirm local weather forecasts and sea conditions before heading out, as wind and wave heights can vary significantly, especially from late autumn through early spring, impacting surface support and entry/exit points.

Recommended Dive Suit
Forecast models show minimal temperature variation in the coming days.
Some divers prefer slightly warmer exposure protection simply for additional comfort. Stronger winds may also make surface intervals feel cooler than usual.
7mm wetsuit or semidry usually works well for maintaining comfort during standard dive profiles in these conditions. Consider warmer surface protection (like a boat coat) due to brisk winds. Surface intervals may feel cooler. Divers preparing to enter the water at Rhode Island will likely find temperatures around 14°C (58°F) today. Surface air temperatures are resting at 18°C (65°F).

Marine Life at Rhode Island
Exploring the varied underwater landscapes of Rhode Island reveals a fascinating array of marine inhabitants. Within the expansive eelgrass beds and across sandy bottoms, divers might encounter clear-nosed skates and pipefish. The vibrant anemone-covered cliff walls and numerous rock formations provide shelter for a variety of species. During the warmer months, the influence of the Gulf Stream occasionally brings temporary tropical life to these waters, including colorful butterflyfish, flounder, and trunkfish. Lucky divers might even spot an octopus peeking out from a rocky crevice or a wreck artifact. While not a coral reef destination, the historical sites themselves become artificial reefs, attracting different species seeking shelter.
