Boothbay Harbor Tide Chart

Boothbay Harbor — Maine’s classic midcoast boating town, where windjammers, whale-watch boats, and lobster boats fill the harbor — rides a big semidiurnal tide of around ten feet.

The pattern

Two highs and two lows daily with around ten feet of range — big midcoast Maine water. The tide floods the harbor and the Damariscotta-side reaches, then drains the mudflats and lobster pounds on the ebb — dock lines need slack for a ten-foot swing.

Working waterfront

Windjammer cruises sail from the harbor all summer, and whale watches run offshore for finbacks and minkes. Lobster boats work the traps right outside the harbor mouth — and the Monhegan ferry leaves for the island artists’ colony; see our best time to fish tides guide.

Boating

The harbor entrance is straightforward but the coast is ledge country — granite hides just under the surface everywhere outside the marked channels. Fog is the summer hazard. For the region, see our New England tides guide.
