Kennebunkport, ME tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are America/New York local. Folk tradition, not a scientific forecast.

Last spring tide on Sun 03 May (range 2.9m / 9.4ft). Next neap on Fri 08 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Kennebunkport sits at the mouth of the Kennebunk River, where a tidal estuary runs 8 kilometres inland through salt marsh and old-growth oak woodland before the river transitions from tidal to fresh. Mean spring range at the river entrance runs around 2.9 metres — enough to transform the harbour dramatically between states. At high water, the Dock Square waterfront and the marina behind it float vessels at the level of the street; at low water, the mussel-covered rocks and tidal flat below the town landing are exposed, and the inner estuary reveals the geometry of the tidal channels through the marsh. Dock Square at the head of the tidal reach is the commercial centre of Kennebunkport — galleries, restaurants, and shops clustered around a small square that is as likely to flood as not during a high astronomical tide coinciding with a northeast storm. The combination of 2.9-metre spring tides and storm surge from a deep coastal low can push water over the square apron and briefly into the lower stores; the owners of lower Commercial Street businesses track the tide chart closely during storm season. Goat Island Lighthouse, visible from Cape Porpoise Pier 5 kilometres north, marks the northern approach to the Kennebunk River entrance from the open ocean. The lighthouse was built in 1835 and is now operated by the Kennebunkport Conservation Trust. The rocky ledge below the lighthouse is accessible by kayak at all but the very lowest spring tides and supports a small harbor seal population that hauls out on the outer rocks. Cape Porpoise Harbour, just north of Kennebunkport proper, is the working lobster harbour of the community — the commercial fleet here is substantial, and the harbour bar at the entrance is depth-limited at low water. Lobster boats time departures to the harbour bar condition: there is adequate depth (roughly 0.6 metres over the bar at mean low water) for most working vessels, but the crossing requires local knowledge on the lowest spring tides. The lobster traps stacked on the Cape Porpoise wharves are moved and deployed on a seasonal basis keyed to both regulation and ocean temperatures. Perkins Cove in neighbouring Ogunquit, 12 kilometres south, is a smaller but famous tidal cove accessible through a pedestrian drawbridge — the Marginal Way cliff path connects the cove to the beach. Whale-watch vessels depart from Perkins Cove in season (May through October) for Jeffreys Ledge offshore, one of the most productive humpback and finback whale feeding grounds in the western North Atlantic. Surf at Kennebunk Beach and Gooch's Beach — both on the open ocean side south of the river mouth — is consistent in northeast and east swell, with the tidal state determining break position and wave quality in the typical pattern: lower water exposes more bar, higher water softens the break and allows entry further up the beach. Summer and autumn are the active surf seasons; winter produces the largest swells but temperatures require a 5mm wetsuit minimum. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge.
