Key Dive Site Facts
Dive Site Overview
Initially, the Old Ponquogue Bridge served as the sole terrestrial link connecting Hampton Bays to the Atlantic Ocean barrier island before the construction of a new, stationary bridge altered the landscape. Today, the area beneath Ponquogue Bridge provides a compelling shore-accessible drift dive experience in Hampton Bays, NY.
Divers typically initiate their descent near the public access points, navigating along the foundational pilings of the old bridge and around the robust stanchions of the newer structure. These submerged architectural elements create a complex habitat where a variety of marine life tends to congregate, offering a rich environment for observation. The maximum reported depth for this site is approximately 2 m / 9 ft, making it distinctly shallow and focusing the dive on horizontal exploration rather than vertical descent.
While popular with local fishermen who utilize the bridges from above, the underwater environment draws divers interested in its structural complexity and the opportunities to observe seasonal marine inhabitants up close. Successful dives here necessitate precise timing around slack tide to ensure a manageable experience within the often-strong tidal currents.
The interplay of man-made structures and natural water flow creates a dynamic underwater setting, appealing to those who appreciate a less conventional dive site.
Best Time to Dive
Considering the conditions, the period from late spring through early autumn typically presents the most favorable diving. Climates indicate that June through October consistently yield 'Good' dive scores, with July and August seeing the warmest average air temperatures around 24.5°C / 76°F and 22.4°C / 72°F respectively. Rain in these months averages between 2.01mm and 3.49mm, suggesting generally drier periods. Early in the dive season, such as March or April, water temperatures can be significantly cooler, around 11°C / 52°F, necessitating dry suits or thick 7mm wetsuits for comfort. As the year progresses into May, water temperatures typically rise, enhancing the overall dive experience. Summertime diving often requires a town of Southampton permit for parking.

Dive Experience & Conditions
Accessing this dive involves a shore entry, making it highly accessible via car in Hampton Bays, NY. Divers should plan their entry just prior to high slack tide to avoid strong currents that can pull quickly towards the Atlantic. While much of the dive explores the pilings of the old bridge, the new bridge's supports also host a variety of life. The bottom consists of areas blanketed with mussels, providing interesting terrain for exploration. Conditions are highly tide-dependent; a careful watch on the current is paramount, particularly near the end of the dive. The maximum depth is shallow, generally around 2 meters / 9 feet, focusing the experience on horizontal exploration of the bridge structures.
Dive Difficulty & Safety Guidelines
Diving at Ponquogue Bridge necessitates a strong understanding of tidal currents, making PADI Drift Diver training particularly useful. It's crucial to enter the water just before high slack tide and limit bottom time to prevent being caught in powerful outgoing currents. Divers should be aware of the boat channel, especially near the end of the old bridge and under the new bridge's wooden pilings, where surfacing should be avoided. A surface marker buoy and dive flag are essential items for signaling position to surface traffic. Additionally, seasonal parking permits are required from the Town of Southampton for access.
