Shore dive with strong current, slack-tide timing, and bay life.
Ponquogue Bridge is a shore dive in Hampton Bays, New York, where the old bridge approaches and nearby bay structure create a current-driven site with a simple but time-sensitive route under the spans. It is best planned around high slack tide, with parking, permit timing, and the channel layout checked before you commit. Seasonal fish and other bay life make the short window worthwhile.

Depth range, seasonality, and planning context.
Reported Depth
1m - 8m
Depth Note
Public references vary between a very shallow shore-dive listing and operator notes around 15 to 25 feet under the old bridge at the right tide, so the structured span is kept conservative.
Best Season
Late spring through early fall, timed to high slack tide.
Typical Conditions
Shallow bay water, strong tidal flow, a tight slack-tide window, and a site that rewards precise timing more than long bottom time.
Site conditions, restrictions, and access requirements.
Site Conditions
Safety Notes
Check tide tables, carry a dive flag, and avoid the channel between the bridges. If the current is moving hard, this is not the day for the site.
Access Restrictions
Parking permits are seasonal on the south side, and the channel between the bridges is not a legal place to dive.
Legal Notes
Follow Southampton park and parking rules and stay out of the channel.
Community notes to help plan your visit.
Scuba Diving
This is a tide-planned shore dive for experienced divers who can work a short slack window and exit before the current builds.
Freediving
Not a routine freedive site; only consider it if you are very comfortable with current and a short tidal window.
Snorkeling
Snorkelling is only practical when the current is tame and the group can stay close to shore; otherwise it is a poor fit.
