Sea Turtles in Maine: identification guide and where to start looking
Sea turtles do visit Maine waters, especially in summer, but sightings are rare. The most likely species are leatherback, loggerhead, and Kemp's ridley. Focus on shell shape, carapace ridges, and flipper size to tell them apart. Start your search along the southern coast and offshore islands from July to October.

What Sea Turtle Species Can Be Found in Maine?
Maine waters host three main sea turtle species: the leatherback, loggerhead, and Kemp's ridley. Leatherbacks are the largest, with a black, leathery shell and seven distinct ridges. Loggerheads have a large head and reddish-brown carapace. Kemp's ridley is the smallest, with a nearly round, gray-green shell. All are listed as endangered or threatened. For more on each species, visit oursea turtle hub.
When Is the Best Time to Spot Sea Turtles in Maine?
The best window is from mid-July to early October, when Gulf of Maine waters are warmest. Sea turtles follow warm currents and prey like jellyfish. Sightings peak in August and September. Cooler temperatures in late fall drive them south. For seasonal wildlife patterns across the state, check ourMaine wildlife guide.
Where in Maine Are Sea Turtles Most Often Seen?
Most sightings occur along the southern coast, from Kittery to Portland, and around offshore islands like the Isles of Shoals and Monhegan. Casco Bay and Cape Elizabeth are reliable spots for leatherbacks. Kemp's ridley turtles are sometimes found stranded on beaches. For detailed spotting locations, see oursea turtle identification page.
How Can You Increase Your Chances of a Sighting?
Consider joining a whale watch or pelagic birding trip, as the same waters attract turtles. Check local stranding networks for recent reports. Scan the surface for dark shapes or flippers breaking the water, especially on calm days. Use polarized sunglasses to reduce glare. For planning your trip, use our travel widget below.

What Are the Key Identification Marks for Each Species?
Leatherbacks: no hard shell, black with white spots, seven ridges along back, front flippers very long and clawless. Loggerheads: large head, reddish-brown carapace with five or more coastal scutes, powerful jaws. Kemp's ridley: gray-green carapace, nearly round, five scutes on each side, adult size under 3 feet. Always look at the shell pattern and head shape first. For more details, visit oursea turtle hub.
What Lookalikes Might Confuse You?
From a distance, a large sunfish (Mola mola) or a drifting log can be mistaken for a sea turtle. Sunfish have a tall dorsal fin and no visible flippers. Seals are often confused, but they have visible ear openings and spotted fur. No animals in Maine closely resemble a sea turtle's shell pattern, so focus on the carapace ridges and flipper movement.

How Do Sea Turtles Behave in Maine Waters?
Sea turtles in Maine are primarily foraging. Leatherbacks dive deep to follow jellyfish, often surfacing for short periods. Loggerheads hunt crustaceans and mollusks. Kemp's ridley turtles feed on crabs. They are solitary and migrate long distances. Most depart Maine by November. Report any sightings to local marine mammal and sea turtle programs.
