The Hawaiian green sea turtle, known locally as Honu, is the most commonly seen sea turtle species around Maui’s shores. These large, hard-shelled marine reptiles are deeply integrated into the cultural fabric of Hawaii, symbolizing good luck, wisdom, and longevity. The Honu is also revered as an ʻaumakua, or a family guardian spirit. Witnessing these graceful animals on the beach or in the water is a highlight for many visitors.
Daily Timing and Basking Behavior
The best time of day to see sea turtles on the shore in Maui is typically during the late morning through the mid-afternoon. This timing relates to basking, a unique behavior where turtles intentionally haul themselves onto the sand or rocks to rest. Hawaii is one of the few places globally where green sea turtles regularly exhibit this behavior.
Basking is a form of thermoregulation, allowing these cold-blooded reptiles to raise their body temperature using the sun’s warmth. A warmer body temperature aids in digestion and helps mobilize stored fat reserves. Turtles seek the warmest parts of the day to maximize this thermal gain, which is why sightings peak when the sun is highest.
An adult Honu can remain on the beach for hours, sometimes up to 48 hours, resting undisturbed. Time out of the water also provides a respite from potential predators like tiger sharks. You are most likely to spot a turtle that has been on the beach for some time, appearing motionless as it rests.
Seasonal Patterns and Nesting Activity
Green sea turtles can be found in Maui’s nearshore waters throughout the entire year, feeding on the abundant algae and seagrass found on the reefs. Their daily basking behavior is not strictly seasonal, meaning there is no single “best” month to see one resting on the beach. However, their annual cycle does include a specific reproductive season.
The nesting season for Honu generally runs from late spring through early fall, typically May through December. Mature females migrate during this time to lay their eggs, a process that occurs every few years. Maui is not a primary nesting destination; approximately 96% of Hawaiian green sea turtle nesting occurs at the remote French Frigate Shoals in the Northwestern Hawaiian Islands.
While localized nesting events occasionally happen on Maui, the vast majority of turtle sightings are of individuals resting or feeding, not nesting. The chance of seeing a turtle haul out to bask is consistent year-round, but the period from May to December holds the slight possibility of encountering a nesting female.
Prime Viewing Locations on Maui
Certain locations on Maui are well-known for frequent turtle visitors, providing reliable places to observe basking behavior. Ho’okipa Beach Park on the North Shore is one of the most consistent spots, especially in the afternoon, where multiple turtles often congregate to rest on the sand. Visitors should look for them near areas protected by sand fencing or barriers.
On the South side of Maui, the stretch of ocean known as “Turtle Town” (which includes Maluaka Beach) is famous for turtle sightings, often while snorkeling. For onshore viewing, Maluaka Beach and Ulua Beach are known for turtles grazing on seagrass and occasionally resting on the sand or nearby rocks. The volcanic outcrop at Black Rock (Pu’u Keka’a) on Ka’anapali Beach in West Maui is another favored spot where turtles are frequently seen in the water along the reef edge.
Another reliable location is the point between Napili Bay and Honokeana Cove, where turtles utilize rocky outcroppings. Kuau Beach Park, near Paia, is a quieter alternative to Ho’okipa, offering a setting where turtles bask in the early mornings or late afternoons. These areas offer the best chance to see the Honu because they provide favorable foraging grounds or secluded, safe beaches.
Rules for Viewing and Conservation
All Hawaiian green sea turtles are protected under state and federal laws, specifically the Endangered Species Act. It is unlawful to harm, harass, or disturb them. This protection is strictly enforced by agencies like the National Oceanic and Atmospheric Administration (NOAA) and the Hawaii Department of Land and Natural Resources (DLNR).
A mandated minimum distance of at least 10 feet (3 meters) must be maintained from any sea turtle, whether resting on the beach or swimming. This rule ensures the animal can rest undisturbed and prevents changes in its natural behavior. Never attempt to touch, chase, feed, or ride a sea turtle; a violation can result in significant fines.
If a turtle approaches you while swimming or snorkeling, calmly move away to restore the required 10-foot buffer. Do not block a turtle’s path to the water or crowd a basking turtle, as they need to be able to leave the beach when ready. Observing these guidelines supports conservation efforts.
