Dive Site Overview
Pinellas II, an integral part of Pinellas County's extensive artificial reef program, holds a notable place in Florida's dive history. It was specifically designed to enhance marine habitats and recreational diving opportunities.
At its core lies the USCG Blackthorn, a 180-foot (55 meters) long ship purposely sunk in 1980, creating a significant wreck for divers to explore. In addition to the Blackthorn, the site incorporates the tug Sheridan and another steel barge, contributing to a diverse underwater landscape. These structures form an artificial reef at a maximum depth of 80 feet (24 meters).
Pinellas County has implemented numerous such reefs, building them from clean, inert debris like concrete and steel since 1975, with over 50,000 tons of material placed to date. Such efforts provide valuable underwater habitats, attracting a variety of marine life and improving local diving experiences.
This ongoing program demonstrates a long-term strategy to foster healthy marine ecosystems within accessible diving ranges.
Best Time to Dive
Assessing the regional climate data provides a clear picture for planning a dive at Pinellas II. While diving is possible all year round, the surface water temperature averages around 26°C (80°F) throughout the year, with annual averages ranging from 25°C to 29°C (78°F to 85°F). Cooler air temperatures are observed in January, averaging 15.48°C (59.86°F), making it the coldest month, while July is typically the warmest with air temperatures around 28.82°C (83.88°F). Dive scores indicate good conditions are frequent from February to September and in November and December. Rain can be a factor, particularly in August, which sees the highest average rainfall at 7.99 mm (0.31 inches). For optimal conditions, periods with lower wave heights and lighter winds, such as July with an average wave height of 0.50 meters (1.64 feet) and wind speeds of 19.75 km/h (12.27 mph), often present favorable opportunities.

Dive Experience & Conditions
Submerging at Pinellas II, divers often encounter visibility between 6 and 30 meters (20 to 100 feet), which can vary significantly depending on current conditions. Primary structures, including the USCG Blackthorn, lie in depths ranging from 65 to 80 feet (19-24 meters). This depth range means divers should be comfortable with deeper recreational limits and potentially cooler temperatures at the bottom compared to the surface. Water movement can also play a role; average wave heights are typically below 1 meter (3.3 feet) for much of the year, though they can increase, particularly in winter months like January and October. Navigating the wrecks requires good buoyancy control and awareness of potential entanglement hazards. Its complex structures offer numerous nooks and crannies to explore, making for an engaging dive experience.
Dive Difficulty & Safety Guidelines
This dive site is classified as an advanced dive, necessitating appropriate certification and experience for safe exploration. Divers should never enter the water without checking with local Pinellas Park dive centers for current safety information and site-specific updates. It's imperative to always be accompanied by a professional, especially when venturing into deeper sections or around wreck penetration points. The guidance provided here is purely informative; it shouldn't replace detailed planning with a local dive operator. Understanding personal limits and equipment functionality before a dive is critical. Given the site's nature, divers should be proficient in wreck diving techniques and emergency procedures.
