Coordinates: N 40° 45.225′, W 72° 59.225′ Positioned north of channel buoys 36 & 37, roughly midway between Fire Island and Moriches Inlet Entrance depth: ~6 ft (MLLW) Dockside depth: ~3 ft (MLLW) Great South Bay tidal range averages around 1.3 ft (max) to 0.1 ft (min) Typical tide times in Patchogue Bay (e.g., first high tide ~12:20 am, low tide ~7:20 am; next high ~12:50 pm) Current & Water Conditions Currents in Great South Bay are generally mild and tidally driven. Expect weak ebb/flood currents near low and high tides. The bay is mostly sheltered from ocean swell, but local wind (especially southwest) can generate choppy wave conditions. Navigation Tips Buoy navigation: Follow buoys 36 → 37 → marina entrance to avoid shoal patches. Tide timing: Arrivals and departures around high tide or slack water maximize under-keel clearance — especially crucial given the shallow dock depth of 3 ft MLLW. Chart datum awareness: Depths listed are relative to Mean Lower Low Water, meaning depths can increase ~1 ft during high tide. Tidal vary: With a narrow tidal range (0.1–1.3 ft), paying attention to tide cycles is vital, but large tidal shifts are unlikely. Wind effects: Be cautious during SW or SE wind events that may create wave surge or wakes at the marina entrance.
