Southport and Oak Island sit side by side in southeastern Brunswick County, and buyers often consider both in the same search. They share a love of boats, beaches and small-town living, yet they feel very different day to day. One is a historic river town at the mouth of the Cape Fear River. The other is a beach town spread along a barrier island and the mainland behind it. Here is a practical comparison to help you decide which fits you better.
Southport and Oak Island at a Glance
Southport is a city near the mouth of the Cape Fear River with a 2020 census population of 3,971. It was founded as Smithville in 1792, served as the Brunswick County seat from 1808 to 1977 and was renamed Southport in 1887. It is home to the North Carolina Fourth of July Festival, which draws tens of thousands of visitors each summer.
Oak Island is a seaside town formed in 1999 when Long Beach and Yaupon Beach consolidated. Its 2020 census population was 8,396, while its summer population approaches 50,000. The town covers most of the island it shares with Caswell Beach, plus mainland areas along N.C. 133, N.C. 906 and N.C. 211. Two high-rise bridges connect the island to the mainland: the Barbee Bridge, opened in 1975, and the Swain’s Cut Bridge, opened in 2010.
Lifestyle: River Town vs. Beach Town
Southport
Southport’s appeal is its walkable historic core, waterfront views of ship traffic on the Cape Fear River, live oaks and a calendar of festivals. Shops, restaurants and marinas are concentrated near the waterfront, and many residents get around on foot or by bike. The NCDOT Southport-Fort Fisher ferry, a crossing of about 35 minutes, links the city to Fort Fisher and Pleasure Island in New Hanover County.
Oak Island
Oak Island is all about the beach. Its oceanfront faces south toward the Atlantic, and life revolves around beach access, fishing, the Intracoastal Waterway and casual seasonal energy. The pace is relaxed in the off-season and busy in summer. If daily beach walks matter more than a downtown, Oak Island usually wins.
Housing: What You Will Find
In Southport, housing ranges from historic cottages and older homes near the waterfront to newer neighborhoods and planned communities on the edges of town. Buying in the historic district comes with its own rules, so read our guide to buying a home in Southport’s historic district before you fall in love with a front porch.
On Oak Island, you will see oceanfront and second-row beach homes, canal and sound-side properties, raised cottages built for flood zones and a growing number of mainland subdivisions. Many island homes are elevated, so inspections should cover pilings, stairs and the area beneath the house.
Flood and Insurance
Both towns include low-lying land near water, so flood zone, elevation and insurance costs can vary widely from one street to the next. Island properties and homes near the river or marsh deserve extra attention. Our flood zones explained guide covers the basics, and you should request insurance quotes early in your due diligence period.
Rentals and Investment
Oak Island has a large vacation rental market tied to its beach, so investors often look there first. Southport draws visitors too, especially around festivals and the waterfront, but its housing stock is more weighted toward full-time residents and second-home owners. Rules for short-term rentals, parking and lodging taxes can change, so confirm current town rules before you buy with rental income in mind.
Getting Around
Both towns connect to the rest of Brunswick County via N.C. 211, with N.C. 133 serving Oak Island and running north toward Leland and Wilmington. Oak Island regulates low-speed vehicles and golf carts on certain streets; see our post on Oak Island’s LSV rules. Expect summer traffic on the island and around Southport’s waterfront during big events.
Schools and Services
Both towns are served by Brunswick County Schools. Assignments are based on address and can change, so verify them directly with the district for any home you consider. Daily shopping is available in Southport and along N.C. 211 near Midway Road, with more options in Leland and Wilmington.
Which Is Right for You?
- Choose Southport if you want a walkable historic town, waterfront dining, festivals and river views, with the beach a short drive away.
