North Shore Swim Series

Welcome to the North Shore Swim Series! The NSSS begins with the Summer Sprint, a 1.0M swim from Sunset Beach to Ehukai Beach Park.

🏁 August 7 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 recreational and competiti

ve 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:
• We employ Hawaii's finest certified Water Safety Patrol on jet skis and surfboards.

• Each swim is electronically timed

• In addition to Individual Event awards for age divisions, event times are combined from all races and Overall NSSS Awards are presented in each age division

One mile. One ocean. A legacy that continues. 🌊🏊‍♀️🏊‍♂️

We caught up with several swimmers moments after completing the Duke’s Ocean Mile during Duke Kahanamoku OceanFest in Waikīkī to hear about their experience.

The event celebrates the life and legacy of Duke Kahanamoku—Olympian, legendary waterman, and ambassador of aloha—whose love for the ocean and swimming continues to inspire generations.

Mahalo to everyone who showed up, took on the mile, and helped carry Duke’s spirit forward. 🤙🌺

And shout out to the event organizers who were able to successfully adapt following last week’s storm.

Swimming is great. Swimming with friends is even better. 🌊🤙

Swimming is often thought of as an individual—or even isolated—sport. But take a look at these photos. 🏊‍♂️❤️

Behind every swimmer are friends, family, significant others, supporters, training partners, and a whole community cheering them on.

Swimming may be done one stroke at a time, but it’s so much better when you have people beside you, waiting for you, cheering for you, and sharing the experience. 🏊‍♀️🏊‍♂️

2K of open water. One stroke at a time. One breath at a time. One goal: keep moving forward.

From the first swimmer to the last, everyone out there had a reason to push through the miles, the waves, and the doubt.

The finish line doesn’t care how fast you got there. It only cares that you kept going. 🌊🏊‍♂️💪

Why the early mornings?
Why the grind?
Why do we keep coming back?

Because of the experiences.
Because of the ocean.
Because of the victories—big and small.
Because of the people beside us, cheering us on, pushing us forward, and sharing the journey.

The alarm clocks. The training. The nerves. The finish lines. The high fives. The memories.
That’s why we swim. 🌊

And we’re just getting started.
Let’s keep making memories. 🤙🏊‍♂️
