Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Off Rhode Island, divers encounter a partially intact passenger ship, the Larchmont, which tragically sank in 1907. This historical wreck currently rests in relatively shallow waters, with main exploration depth typically ranging from 5.0–15.0 m (16–49 ft).
While a maximum recreational dive depth of 30 m (100 ft) is generally possible in the broader area, the structure of the wreck itself primarily keeps diver activity within these shallower sections. Much of the Larchmont's original form remains recognizable, allowing for navigation around its hull and scattered debris field. Divers typically plan for an average dive time of 40 minutes, providing ample opportunity for thorough observation of the site.
Extensive marine growth often covers the entire structure, effectively transforming the vessel into a vibrant artificial reef. This organic blanket of soft corals and anemones attracts a diverse array of smaller organisms, enhancing the visual appeal.
Throughout the year, water temperatures fluctuate significantly; summer brings warmer conditions between 18–24°C (64–75°F), while winter can see temperatures drop to 4–10°C (39–50°F). These considerable variations directly influence the specific exposure protection necessary for a comfortable and safe dive at any given time.

Best Time to Dive
Maximizing visibility at the Larchmont wreck is key for an optimal dive experience, making June through September particularly advisable. During these months, average visibility typically ranges from 5.0–15.0 m (16–49 ft). Air temperatures are most comfortable, averaging 17°C (63°F) in June, peaking at 21°C (70°F) in July, and remaining pleasant through September at 19°C (66°F). Rainfall is generally moderate, with averages between 2.3 mm and 4.2 mm, which tends to minimize runoff impacting water clarity. Additionally, wind speeds are lower and wave heights are milder, averaging between 0.8-1.0 m (2.6-3.3 ft), contributing to calmer surface conditions. Consistently, warm water temperatures of 18–24°C (64–75°F) during this period enhance dive comfort and extend bottom time, aligning with good dive scores.

Dive Experience & Conditions
Mild currents and moderate surge interplay to define the underwater environment at this Rhode Island site. Currents are not consistently reported as strong, generally remaining mild, aiding navigation around the wreck. However, divers should be prepared for moderate surge, especially during tidal changes or adverse weather, necessitating good buoyancy control. Visibility at the Larchmont wreck typically ranges from 5 to 15 meters, varying with seasonal conditions and recent weather patterns. Shallower sections often hold better clarity. Summer water temperatures are comfortable, sitting between 18–24°C (64–75°F), but winter conditions are significantly colder, dropping to 4–10°C (39–50°F). Bottom composition around the wreck consists primarily of sand, rubble, and the wreck itself, offering a diverse substrate for marine life. Surface conditions are generally calmer during late spring and summer, with average wave heights around 0.8-0.9 meters (2.6-3.0 feet).
Dive Difficulty & Safety Guidelines
Wreck diving inherently carries specific considerations, and the Larchmont wreck is no exception. While permits are not required for diving this site, understanding its moderate surge conditions is crucial for maintaining safe clearances from the wreck and preventing accidental contact. Divers should practice excellent buoyancy control to avoid disturbing the wreck or stirring up silt, which can quickly reduce visibility. Given that the wreck is partially intact, divers should avoid attempting any penetration without appropriate training, equipment, and a clear understanding of the risks involved. Always dive within your certification limits and consider the experience level of your buddy. The relatively shallow depth of the wreck allows for ample bottom time, but vigilance regarding air consumption and no-decompression limits remains essential.

This gear list is based on verified equipment signals for Larchmont, United States. Always confirm final gear choices with your dive operator, guide, or liveaboard.
Recommended Dive Suit
For dives of average duration, 5-7mm wetsuit usually provides sufficient protection from heat loss. Consider warmer surface protection (like a boat coat) due to brisk winds. Surface intervals may feel cooler.
Divers entering the water at Larchmont today can expect temperatures near 16°C (60°F) beneath the surface. Surface air temperatures are resting at 19°C (67°F).
Environmental conditions may feel slightly cooler as the week progresses. Cooler days are ahead; you might want a warmer option for later in the week. Having a second exposure option available is often a good precaution.
