Welcome to the North Shore Swim Series, a premier open water festival comprising of 4 swims (plus the 5k/10k Endurance Swim) along Oahu's fabled North Shore
*North Shore Flood Resources: Each summer the North Shore Swim Series kicks off the highly anticipated season of ocean swimming with its popular race cache of open water events. Now entering its 37th year, the NSSS gives recr
eational and competitive swimmers alike a chance to test their mettle (as well as enjoy the scenery) in the beautiful waters of Oahu's fabled North Shore. This swim is truly a "sprint" as finishing times are often under 20 minutes for the elite swimmers! Swimmers usually encounter following seas and small surf along the surf as it passes many popular winter surfing breaks. The second event, the Waimea Bay Swim, is a 1.2M swim circling Waimea Bay. The event is popular because of its crystal clear water and convenient location. The swim course changes from year to year, adding variety into this event. The third swim, the Chun's to Waimea Bay Swim, is a 1.6M swim starting at Chun's Reef and ending at Waimea Bay. This course can be challenging as competitors often swim upwind for much of the course. Participants say the spectacular views on offer from this course are well worth the effort. The final swim, the North Shore Challenge, is from Ehukai Beach Park, the home of the famous Banzai Pipeline, to Waimea Bay. At 2.3M it is the longest and most prestigious of the 4 swims. It is considered the most scenic both above and below the water. BASIC INFORMATION:
