Overview
Kahului Harbor sits on the north-central coast of Maui and is a genuinely fun place to score, with several breaks firing inside and outside the harbor. The standout is the right on the west side. When a large swell pushes through the wide entrance, energy refracts out of the deeper channel and crosses up with swell bouncing off the jetty, stacking into a powerful roll-in wedge over shallow water. It is a mini-Box-style wedge that rewards surfers and bodyboarders who can handle abrupt steps and throw into barrels. There is a left off the same peak, but it dumps straight into the deep channel and does not offer much. Treat it as more of a novelty than a world-beater, though it is a blast when it turns on.
When It Works
The harbor draws swell from northwest through north to east-northeast (NW-N-ENE), and everything really lights up on a solid north swell through autumn, winter, and spring. The wedge is usable from 1.2 m / 4 ft to 2.1 m / 7 ft, running chest-high to overhead when it is on. With a bottom of reef, lava, rock, coral, and sand, it holds a punchy, slabby shape.
Wind and Tide
Offshore is south-southwest (SSW), and the workable wind window runs from south to west-southwest (S-WSW), which lines up with the calm or southerly-to-westerly flow that comes through on passing fronts. It prefers lower water, working through low and mid tide, with a rising tide generally the better call.
Local Tips
This one suits intermediate to expert surfers on a shortboard, bodyboard, or bodysurfing. Expect a moderately busy lineup when it is working; it stays quiet when the swell is small or the wind is off, then fills in fast during a solid northerly swell, especially once the wind shifts from the south to the west. Humility and respect go a long way here.
Access
Getting there is easy: park at the harbor and jump in right at the lineup. The paddle out is straightforward, though the current can make it tough to hold your position once you are in the spot. Keep in mind you are surfing inside a working harbor with noticeable pollution, and watch for the shallow bottom on the right wedge, urchins, rocks, sharks, and shifting rips.
