Sea Isle City is a city in Cape May County, New Jersey, United States. It is part of the Ocean City Metropolitan Statistical Area. As of the 2010 United States Census, the city’s population was 2,114, reflecting a decline of 721 (-25.4%) from the 2,835 counted in the 2000 Census, which had in turn increased by 143 (+5.3%) from the 2,692 counted in the 1990 Census. Visitors raise the population to as much as 40,000 during the peak summer season from Memorial Day to Labor Day. Sea Isle City is located on Ludlam Island, which also contains the Strathmere section of Upper Township.

Sea Isle City was originally incorporated as a borough on May 22, 1882, from portions of Dennis Township, based on the results of a referendum held six days earlier. The borough was reincorporated on March 31, 1890. In March 1907, portions of Dennis Township and Upper Township were annexed to Sea Isle City. In April 1905, portions of Sea Isle City were annexed to Upper Township. On April 30, 1907, the area was reincorporated as the City of Sea Isle City, based on the results of a referendum held on April 20, 1907. The name derives from its location on the Atlantic Ocean.

Sea Isle City was founded in 1882 by Charles K. Landis, who was also the founder of Vineland, New Jersey. The main street in town, Landis Avenue, is named for the town’s founder. The oldest building in Sea Isle City is The Colonnade Inn, a Victorian building dating back to the 1800s. From 1885 until 1924, Sea Isle City was the location of Ludlam’s Beach Lighthouse. The structure was moved to the corner of Landis Avenue and 35th Street (3414 Landis Ave), and was a private residence (rental) for many years. A non-profit group, The Friends of the Ludlam Beach Lighthouse, was unsuccessful in its efforts to raise enough money to save the building from demolition by moving it to a new location and restoring it. It was demolished on September 21, 2010, to make way for new town homes.

The oil tanker MV Sea Isle City was renamed for this city when it was reflagged and registered in the United States in 1987 during Operation Earnest Will. It was struck by a Silkworm missile off Kuwait on October 16, 1987, wounding 18 crew members and seriously damaging the ship.

Sea Isle City has long been popular with summer visitors. In 2002, the printed message on its signature water tower was changed from “Welcome to Sea Isle City” to “Smile! You’re in Sea Isle City”. The word “City” was later removed from the message in 2018.

The “Sara the Turtle Festival” is one of the city’s annual festivals, celebrating a fictional turtle named Sara. Aimed towards families with young children, the festival features live animal exhibits and face painting meant to educate children about the local environment. The city hosts a Polar bear plunge every February, holding the 25th annual event in 2019, featuring many participants dressed in costume.

In 1999, the city’s only amusement park, Fun City, was closed and the land was sold for development of beach homes. In 2009, a new amusement park called Gillian’s Funland was opened on JFK Boulevard by the bay as a public-private venture between Sea Isle City and neighboring Ocean City mayor Jay Gillian. Funland was permanently removed, however, following the 2013 summer season for financial reasons in part due to losses from Hurricane Sandy.

In 2011, Sea Isle City began a $14 million makeover to create a public corridor from the bay to the ocean. Plans included a new boathouse on the marina, installing a new playground and basketball courts on JFK Boulevard and erecting a pavilion and band shell at Excursion Park on the city’s Promenade overlooking the Atlantic Ocean. Sea Isle City became one of the first towns in New Jersey, along with Salem City and Egg Harbor City, to receive LED streetlights powered solely by wind and solar energy. The lights were installed at the Promenade at JFK Boulevard by the South Jersey Economic Development District and the New Jersey Institute of Technology.
