Kahalu'u Bay surf guide

Kahalu'u Bay is a popular surf spot located on the Big Island of Hawaii. It's known for its easy access and a variety of waves that cater to surfers of different skill levels. Located right next to Kahalu'u Beach Park, it's a place where you can catch some waves while enjoying the beautiful surroundings. It's often crowded with beginners, but you'll also find some intermediate surfers looking to have fun out there.

The surf here mostly rolls in with a mellow vibe, making it perfect for newbies. However, when solid south or southwest swells hit during spring and summer, the outer peak can offer fun lefts and rights, with wave sizes ranging from about waist to head high (1 to 2.5 meters). The bottom is primarily made up of reef, coral, and lava, which can be a little tricky if you're not careful. A good day usually features medium tides and clean conditions, especially in the morning before the afternoon seabreeze kicks in. You can expect to see waves handling sizes from about 4 to 8 feet (1.2 to 2.4 meters), so there's definitely something for everyone, whether you're on a shortboard, funboard, or longboard.

Paddling out is fairly easy on smaller days, but it gets a bit more challenging as the waves get bigger. Crowds can be a common sight at Kahalu'u, so keeping a friendly local vibe is key. Just remember to be respectful and watch out for other surfers and their boards, especially when the tide is low. Overall, this spot is a great choice for beginners most of the time, and on good swells, even intermediates can find some fun waves to ride.
