Wild dolphins are frequent visitors and, in some cases, year-round residents of the South Carolina coast, particularly in the waters surrounding Myrtle Beach and the greater Grand Strand area. The local environment, with its mix of oceanfront, tidal creeks, and inlets, provides a rich habitat for these intelligent marine mammals, making sightings common for residents and visitors alike.
The Species Present and Their Residency
The dolphin species most commonly observed in the region is the Common Bottlenose Dolphin, scientifically known as Tursiops truncatus. This population is not monolithic, but rather a complex mix of different groups utilizing the coastal waters. Researchers recognize three distinct types: resident, coastal, and migratory dolphins.
The resident dolphins often remain in the shallower, protected estuarine and inlet waters, such as those around Murrells Inlet, throughout the year. These groups rely on the stable food sources available in the tidal creeks, even during the winter months. Conversely, coastal and migratory dolphins travel along the Atlantic coast, moving south in cooler seasons and returning north as water temperatures rise. The presence of both resident and transient groups ensures that dolphins can be seen in the Myrtle Beach area consistently.
Seasonal Movement and Prime Viewing Locations
Dolphin abundance increases when migratory pods join the resident groups, peaking from late spring through early fall. The greatest number of dolphins is seen in the summer months, with a surge in activity during the southward migration in October and November. This movement brings large groups of dolphins close to shore as they follow schools of prey like mullet and menhaden.
To maximize the chance of a successful sighting from the shore, focus on areas where the ocean meets the inlets or man-made structures. Fishing piers, such as the one at Myrtle Beach State Park, and jetties, like those at Huntington Beach State Park, offer elevated vantage points. Dolphins frequently utilize these structures for hunting, often feeding actively during the low-light periods of dawn and dusk. The Intracoastal Waterway entrance near Little River is another prime location, as the dolphins move between the ocean and the calmer inland waters.
Safe and Legal Dolphin Viewing
For guaranteed viewing opportunities, several commercial dolphin watch cruises operate out of nearby ports like Little River and Murrells Inlet. These tours utilize specialized vessels to take passengers into the Atlantic Ocean, often locating dolphins feeding behind active shrimp trawlers. Reputable commercial operators are experienced in finding dolphins while adhering to strict wildlife protection guidelines.
Harassing, feeding, or attempting to swim with wild dolphins is prohibited, as mandated by the federal Marine Mammal Protection Act (MMPA). This legislation prevents human interference with their natural behaviors, such as feeding and resting. When viewing from a private boat or personal watercraft, federal guidelines require maintaining a minimum distance of 50 yards from dolphins, porpoises, and sea turtles. Boaters must avoid chasing the animals; if a dolphin approaches the vessel, the engine should be placed in neutral to prevent accidental injury.
