If you’re walking a Hawaiian beach this summer and see what looks like a large gray rock with whiskers, do not walk up to it. Hawaiian monk seal pupping season peaks from March through August, although monk seals can give birth year-round. (NOAA Fisheries — peak pupping season guidance)

Keep children and pets well away. A mother resting with a newborn may have a black, woolly pup beside her; older pups can become silvery gray. From a distance, do not try to decide whether a seal is nursing, resting, or alone. Give it room either way. Hawaiian monk seals are endangered marine mammals. (NOAA Fisheries — Hawaiian Monk Seal)

NOAA Fisheries and Hawaiʻi DLNR published pupping-season guidance on April 17, 2026, asking beachgoers to give seals space and report sightings. (NOAA Fisheries; Hawaiʻi DLNR) Keep DLNR’s monk seal guidance handy, too. Local reporting has also tracked the start of the 2026 season.

Keep at least 150 feet from a mother and pup, on land or in the water. NOAA describes that nursery bubble as roughly three to four school buses parked nose-to-tail. It feels generous because it needs to be. Disturbance can interrupt nursing or cause a mother to abandon a pup. A dependent pup abandoned without intervention is at grave risk. (NOAA Fisheries — Frequent Questions About Monk Seal Mothers and Pups)

For any other monk seal, keep at least 50 feet away. That includes a seal hauled out to rest or molt. (Hawaiʻi DLNR; NOAA Fisheries — Viewing Marine Wildlife in Hawaiʻi)

If a seal swims near your snorkel spot, move away and do not follow it for a photo. Keep 150 feet from a mother-pup pair and 50 feet from another seal in the water. You are the guest in that reef.

Hawaiian monk seals are endangered. NOAA estimates a total population of about 1,600 animals across a 1,500-mile stretch of the Hawaiian archipelago. Nearly 1,200 live in Papahānaumokuākea and the Northwestern Hawaiian Islands, while about 400 live in the Main Hawaiian Islands. Both populations have increased since 2013, with significant growth in the Main Hawaiian Islands. (NOAA Fisheries — Hawaiian monk seal science)

Monk seals are protected under the federal Marine Mammal Protection Act and Endangered Species Act. Under the Marine Mammal Protection Act, harassment includes pursuit, torment, or annoyance that could injure a marine mammal or disrupt behavior such as nursing, feeding, breeding, or sheltering. Causing a seal to leave its resting place can cross that line. Penalties can include substantial fines and criminal penalties. (NOAA Fisheries — Marine Mammal Protection Act; NOAA — Marine Mammal Protection Act enforcement)

Save 888-256-9840 before your trip. This is NOAA’s Hawaiʻi statewide marine-animal stranding, entanglement, and reporting hotline. Call if you find a seal in distress, entangled in gear, or being crowded by people. Responders may assess the situation and establish a protective perimeter if it is needed.

Monk seals occur throughout the Main Hawaiian Islands and use land to haul out. No beach offers a reliable wildlife appointment, so treat every beach encounter as unscheduled and give the animal its space. (NOAA Fisheries — Hawaiian monk seal science)

Poʻipū Beach, Kauaʻi. If a seal has hauled out here, do not turn the beach into a viewing attraction. Give it the full recommended distance and follow any posted barriers.

Kaimana Beach / Sans Souci, Oʻahu. This beach has been a repeat pupping site. Rocky pupped here in 2017 and 2022, and Kaʻiwi pupped here in 2023 and again in 2026. At documented mother-pup events, responders have installed fencing and placed personnel on the beach to help visitors stay back. (NOAA Fisheries; Hawaiʻi DLNR)

Turtle Bay and the North Shore, Oʻahu; Kaʻanapali and Kīhei, Maui; South Kona and Punaluʻu, Hawaiʻi Island. These are beach areas where an encounter calls for the same response: stop, create space, and report a sighting when appropriate. At Punaluʻu, NOAA recommends 10 feet from green sea turtles and 50 feet from Hawaiian monk seals. (NOAA marine wildlife-viewing guidelines; NOAA Fisheries — Viewing Marine Wildlife in Hawaiʻi)

The simple rule is better than a beach list: any island beach can surprise you. Look before you set down your towel.

If you are already too close, move away calmly while watching your footing. Give a mother and pup 150 feet. Give another monk seal 50 feet.

Call the hotline at 888-256-9840. Tell the operator the island, beach, and your nearest landmark or lifeguard tower. GPS coordinates help. Mention crowding or an apparent injury. (NOAA Fisheries — report marine-animal sightings)

Do not herd a seal toward the water. Hauling out is normal behavior. Monk seals rest and molt on beaches, and mothers nurse pups there. A seal on sand is not automatically stranded. Pushing one into the surf can disrupt its resting or sheltering behavior. (NOAA marine wildlife-viewing guidelines)

Keep pets leashed and far away. Toxoplasmosis enters the environment through cat feces, and dogs can directly injure seals or spread disease. (NOAA Fisheries — toxoplasmosis and Hawaiʻi marine animals; NOAA Fisheries — Disease causes three Hawaiian monk seal deaths)

Do not feed, pour water on, or touch a seal. Feeding monk seals is illegal and can habituate wildlife, increasing dangerous human-seal interactions. (Hawaiʻi DLNR)

Take photos from the approved distance. Use your zoom lens. A close portrait is not worth disturbing an animal that came ashore to rest.

Not every hauled-out seal is easy to spot. Slow down if something on the sand looks like a rock with flippers.

Posted signs, cones, fencing, or other barriers can mark a protected area. Stay behind them. Hawaiʻi DLNR specifically directs visitors to remain behind posted signs, cones, and barriers around monk seals. (Hawaiʻi DLNR)

A quiet cluster of people standing far back can also be a clue. Do not assume a crowd knows the right distance. Check where the seal is, then create your own buffer.

Tracks above the high-water mark are another signal. Parallel flipper marks leading from the water to a “rock” deserve a second look from where you are.

If you see no signs and no seal, enjoy the beach as usual. Keep watching as you walk. A seal does not need a sign to deserve space.

Kids are the soft spot in the system. Adults may read a sign. Kids see a big furry animal and want to run toward it. Have the conversation before you reach the sand.

A version that works for most kids: “Some beaches in Hawaiʻi have sleeping seals. They look like big gray pillows. If we see one, we stay far away and watch quietly. That helps the seal rest and helps its baby stay safe.”

Older kids can handle the legal frame. Monk seals are protected by federal law, and bothering one can bring real consequences. Make the seal a rare animal they may be lucky enough to see, not a forbidden prop for a photo.

There are legitimate ways to learn about Hawaiian monk seals without crowding a wild animal.

The Waikīkī Aquarium (Oʻahu) currently cares for Hōʻailona, a Hawaiian monk seal who returned in September 2025 after a temporary research placement in California. Check the aquarium’s current information before planning your visit. (University of Hawaiʻi; Waikīkī Aquarium webcam; Hoodline — Beloved Hawaiian Monk Seal Hoʻailona Returns to Waikīkī Aquarium, September 2025) Read our Waikīkī Aquarium guide.

Poʻipū Beach Park (Kauaʻi) can still deliver a meaningful wild-seal encounter if one happens to be hauled out. Do not plan on managed viewing, and do not approach for a better look. Follow barriers if they are present.

Hawaiʻi Marine Animal Response. HMAR conducts shoreline response and outreach. Check the HMAR website for current information and opportunities.

Snorkel and boat tours may encounter monk seals, but a tour should never promise swimming with them. NOAA advises visitors not to engage with monk seals in the water. If an operator pitches that experience, book elsewhere. Browse Hawaiʻi tours on Viator. Affiliate link.

If your first-choice beach has a protected seal area when you arrive, use a backup beach. The seal stays as long as it needs to stay.

Hawaiian monk seals remain endangered, even as populations in both the Northwestern and Main Hawaiian Islands have increased since 2013. Their recovery depends on ordinary choices made on the beach: leave space, keep pets away, and report trouble. (NOAA Fisheries — Hawaiian monk seal science)

NOAA’s 150-foot buffer is viewing guidance for mothers and pups. Federal law separately prohibits harassment that can disrupt normal behavior, including nursing and sheltering. Do not wait for a posted rope or a responder to make the right call.

You do not need to do anything heroic. Look before you spread the towel. Keep your dog leashed. Call the hotline if you see trouble. If you spot a seal this summer, stand back and let it rest in the sand.
