Loggerhead sea turtles are rare visitors to New Hampshire's coastal waters, most likely found offshore in summer. This field guide covers where they might appear, when to look, and how to identify one if you're lucky enough to spot it.

1. What is a loggerhead sea turtle and why might it be in New Hampshire?

Loggerhead sea turtles are large, hard-shelled reptiles that usually live in warmer Atlantic waters. Occasionally, young individuals stray north with warm currents in summer. They are not common in New Hampshire, but sightings have been recorded in the Gulf of Maine. Learn more on theloggerhead sea turtle species page.

In New Hampshire, loggerhead sea turtle sightings usually improve when you slow down and match your first stop to likely habitat. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.

2. What is the likely habitat of loggerhead sea turtles in New Hampshire?

If a loggerhead appears, it will most likely be in open ocean waters rather than close to shore. Look near the surface in areas with converging currents or floating seaweed. They do not nest in New Hampshire, so any sighting will be a pelagic individual passing through.

3. When is the best time to see a loggerhead sea turtle in New Hampshire?

The best odds are from July to September when sea surface temperatures peak. Even then, sightings are extremely rare. Focus your search after a stretch of warm weather when southern currents push warmer water north. Check theNew Hampshire wildlife pagefor other species you might see during the same season.

4. What is one practical clue for beginners to identify a loggerhead sea turtle?

Look for a large, reddish-brown shell with five pairs of costal scutes (the plates on each side of the center). Their head is noticeably large and blocky. If you see a sea turtle in New Hampshire waters, it is almost certainly a loggerhead or a leatherback. Loggerheads have a hard shell, unlike the leathery shell of a leatherback.

5. Where have loggerhead sea turtles been spotted in New Hampshire?

Most documented sightings come from offshore areas near the Isles of Shoals and the mouth of the Piscataqua River. A few have been stranded on beaches after storms. For recent records, contact the New Hampshire Fish and Game Department or local marine mammal stranding networks.

6. How can you increase your chances of seeing a loggerhead sea turtle?

Take a whale watch or pelagic birding trip in summer when boats go farther offshore. Keep binoculars handy and scan for any dark shapes breaking the surface. Loggerheads sometimes bask at the surface, but they are quick to dive. Patience and calm seas help.

7. What should you do if you see a loggerhead sea turtle in New Hampshire?

Stay at least 50 feet away and do not harass the animal. Report your sighting to the New Hampshire Marine Mammal Rescue team or call 1-800-452-7888. Take photos if possible to help confirm the species. Never attempt to touch or ride a sea turtle.
