Dolphins are regularly seen in the waters off Myrtle Beach and the surrounding Grand Strand area. These marine mammals inhabit the nearshore Atlantic Ocean and frequently venture into local inlets and estuaries. Observing these animals in their natural environment is a popular activity for visitors and residents.
The Atlantic Bottlenose Dolphin Population
The primary species sighted along the South Carolina coast is the Common Bottlenose Dolphin, specifically the coastal form, Tamenend’s bottlenose dolphin. Research indicates the presence of at least three distinct population groups in the region: year-round residents, seasonal residents, and migratory dolphins. The resident dolphins often remain in sheltered estuarine systems, such as the Intracoastal Waterway and local rivers, throughout the year.
These highly social animals travel in groups called pods, which vary in size from a few individuals to larger aggregations. They exhibit complex behaviors, including cooperative feeding strategies and sophisticated communication. Bottlenose dolphins typically reach a length of 10 to 12 feet, possessing a sleek, gray body and a distinctively curved dorsal fin.
Prime Viewing Seasons and Geographical Hotspots
The best time of year for dolphin sightings in the Myrtle Beach area is typically from late spring through early fall, spanning from April to September. This period corresponds with warmer water temperatures, which draw migratory and seasonal dolphin groups closer to the shore as they follow their prey. Sightings are also common during the morning and late afternoon hours, when the water is often calmer, making the animals easier to spot near the surface.
Dolphin activity concentrates in several predictable geographical areas along the Grand Strand. They are frequently seen just beyond the surf line, riding waves and feeding on schools of fish. Specific hotspots include the mouths of inlets, such as Murrells Inlet, where they access the local estuary system, and around man-made structures like jetties and fishing piers, which attract fish and offer deeper water access.
Dolphin Viewing Tours and Ethical Interaction
For a close and reliable viewing experience, a variety of guided boat and kayak tours are available from local marinas. These excursions often navigate the nearshore ocean and inlets, where guides use their experience to locate active pods. Some tours utilize specialized equipment, such as hydrophones, to allow passengers to hear the dolphins’ vocalizations underwater.
Interaction with marine mammals is governed by the federal Marine Mammal Protection Act (MMPA), which prohibits harassment, feeding, or disturbing them. Responsible viewing mandates maintaining a safe and respectful distance; boats should slow down and avoid approaching dolphins head-on or chasing them. Never attempt to feed the dolphins, as this alters their natural foraging behavior. Viewing from the shore is also possible, and using polarized sunglasses and binoculars can help spot their dorsal fins breaking the water’s surface.
