Myrtle Beach overview

Myrtle Beach is a coastal beach feature on the Atlantic coast of the United States. It sits within the Grand Strand and is located at approximately 33.6891°N, 78.8867°W, forming part of a roughly sixty-mile arc of South Carolina shoreline. The Myrtle Beach shoreline is significant for its role as a developed barrier beach with extensive beachfront urbanization and repeated coastal engineering projects that have altered beach width and dune form.

Where Myrtle Beach is located

Myrtle Beach lies in Horry County on the eastern seaboard of South Carolina, facing the Atlantic Ocean. The beach occupies the central portion of the Grand Strand, positioned south of North Myrtle Beach and north of Garden City Beach. Inland from the shore are tidal creeks, the Intracoastal Waterway, and low coastal plain terrain that transitions quickly from dunes to developed parcels. Offshore waters include nearshore sandbars and the continental shelf break several tens of kilometers seaward.

Why Myrtle Beach is important

Myrtle Beach matters as a developed segment of an Atlantic barrier system where human engineering and natural processes intersect repeatedly. The shoreline has been the subject of periodic beach nourishment and coastal stabilization campaigns led by municipal authorities and federal contractors. Its developed beachfront, piers, and boardwalk infrastructure exemplify long-term coastal urbanization patterns on South Carolina’s coast. Ecologically, the dune and intertidal zones at Myrtle Beach provide habitat for shorebirds and support seasonal nesting by sea turtles along parts of the Grand Strand.

History of Myrtle Beach

Myrtle Beach formed as a Holocene barrier shoreline shaped by rising post-glacial sea levels that deposited sand along the coast and created dune ridges. For centuries the area remained sparsely settled, used for fishing and maritime resources by local communities. In the twentieth century the Myrtle Beach shoreline underwent planned development that introduced hotels, boardwalks, and amusement structures, transforming the physical coastline. During the later twentieth century, increased erosion and storm impacts prompted engineered responses such as renourishment campaigns, hardening in select locations, and municipal shoreline management practices.

Natural features of Myrtle Beach

The Myrtle Beach shoreline is a low-gradient, seaward-facing barrier with broad tidal flats, nearshore sandbars, and shore-parallel dune fields composed largely of fine quartz sand. Dune heights vary locally, with rebuilt foredunes engineered for storm attenuation where development is dense. Built features along the Myrtle Beach seafront include boardwalk sections, pier structures extending into the surf, and localized hardened structures adjacent to developed blocks. Sediment textures and beach slope produce an exposed, wave-dominated surf zone typical of the mid-Atlantic coastal plain.

Environment, protection, and monitoring of Myrtle Beach

Myrtle Beach’s coastal management involves municipal and county ordinances, state coastal programs, and periodic federal involvement for engineering projects addressing erosion and storm damage. Conservation efforts emphasize dune preservation, habitat monitoring for shorebirds and sea turtles, and sediment budget assessments that inform renourishment design. Long-term stewardship balances shoreline stabilization with attempts to maintain dune systems and intertidal habitats, while monitoring programs document shoreline change and sediment transport along the Myrtle Beach sector of the Grand Strand.

Myrtle Beach facts

Myrtle Beach occupies the central section of the Grand Strand, an approximately sixty-mile arc of Atlantic shoreline on South Carolina’s coast. The shoreline at Myrtle Beach is underlain predominantly by fine, white quartz sand derived from reworked coastal plain sediments. A major phase of beachfront development converted the Myrtle Beach shore from sparsely used coastal land to a concentrated resort and recreational seafront during the twentieth century. The Myrtle Beach seafront includes multiple piers and boardwalk elements that have been focal points of its built coastal landscape. Federal and local coastal engineering programs have repeatedly implemented beach nourishment on the Myrtle Beach shoreline to address erosion.
