In September 1994,
Six Flags announced plans to build a new water park in
Valencia, California, adjacent to the
Six Flags Magic Mountain amusement park. The water park was named Six Flags Hurricane Harbor and opened in 1995. Six Flags additionally filed a
trademark for the Hurricane Harbor name with the
United States Patent and Trademark Office on November 4, 1994. Six Flags would later acquire the
Wet 'n Wild water park in
Arlington, Texas, in April 1995, which operated with the
byline "A Six Flags Park." It was speculated in November 1996 that park executives were debating whether to rename the Wet 'n Wild as simply Hurricane Harbor with the "A Six Flags Park" byline or Six Flags Hurricane Harbor. The Arlington park was ultimately
rebranded as the latter in 1997. 's Hurricane Harbor opened in 2003 as part of Six Flags' growing efforts to grow the brand in the 2000s. Throughout the late-1990s through the 2000s, Six Flags would start to expand the Hurricane Harbor brand through the construction of new water parks or rebranding existing water parks attached to their theme parks. In 1999,
Six Flags St. Louis constructed its own
intra-park water attractions section. Two Hurricane Harbor water parks would open in 2000:
Six Flags Great Adventure in
Jackson Township, New Jersey opened the
Hurricane Harbor New Jersey water park in May 2000 after three years of planning; the recently-acquired
Six Flags Worlds of Adventure in
Aurora, Ohio also opened one as part of a large theme park expansion. In 2003,
Six Flags New England in
Agawam, Massachusetts, renamed and expanded their Island Kingdom water park to Six Flags Hurricane Harbor. The Aurora, Ohio, Hurricane Harbor was sold to
Cedar Fair in 2004, as part of the sale of Six Flags Worlds of Adventure. It was renamed Hurricane Hannah's Waterpark before it was ultimately abandoned in 2006. Most of its attractions were relocated to a new water park on the other side of the property named
Wildwater Kingdom. Another two Hurricane Harbor-branded water parks would open in 2005.
Six Flags America in
Woodmore, Maryland, rebranded their existing Paradise Island water park into a Hurricane Harbor. After a
failed attempt to build a water park in the late-1990s,
Six Flags Great America in
Gurnee, Illinois, opened
their Hurricane Harbor next to the theme park. Six Flags would not build another Hurricane Harbor water park until 2014, when
Six Flags Over Georgia in
Mableton, Georgia added a water park. In 2015, Six Flags acquired an abandoned water park in
Oaxtepec,
Morelos. It was renamed Hurricane Harbor Oaxtepec, renovated, and reopened in 2017 under its new name. In the late 2010s, Six Flags would acquire lease rights to operate multiple water parks owned by
EPR Properties, most of which Six Flags had previously owned. These properties included
Waterworld Concord (renamed Hurricane Harbor Concord in 2018),
Wet 'n Wild Splashtown (renamed Hurricane Harbor Splashtown in 2019),
White Water Bay (renamed Hurricane Harbor Oklahoma City), and
Wet 'n Wild Phoenix (renamed Hurricane Harbor Phoenix in 2020). Additionally, Six Flags acquired lease rights from the
Rockford Park District to
Magic Waters in
Cherry Valley, Illinois, for 10 years in 2018. It was renamed to Hurricane Harbor Rockford in 2020. It was announced in 2021 that Great America's Hurricane Harbor park would operate as a separate property, becoming
Hurricane Harbor Chicago. In 2023,
White Water Bay, next to
Six Flags Fiesta Texas, was renamed to Hurricane Harbor San Antonio. Hurricane Harbor Maryland at
Six Flags America was permanently closed on September 6, 2025, ahead of its adjacent theme park's official closure on November 2, 2025. == Locations ==
