Kahului Harbor Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a long stretch ahead, and I gotta be straight with you—it’s a rough one. The only break on the menu is Kahului Harbor, and looking at the next 16 days, it’s mostly a write-off. There’s a massive gap right at the start with no surf worth mentioning. We’re looking at a solid 13 days of poor conditions before anything even remotely rideable shows up.

The first real glimmer of hope comes on Tuesday, September 1st. The swell bumps up to 8 ft from the E, with a long period of 13 seconds. That’s some proper groundswell energy, and the combined energy is a whopping 2252, which is very strong. But here’s the kicker: the wind is cross-onshore, moderate, and it’s a reef setup. The forecast calls it marginal, and the water temp is about average for this time of year. For a spot like this, that long-period swell is gonna be powerful, but the wind is going to chop it up. It’s a big wave, and honestly, at 8 ft, it’s pushing into expert territory. The direction is ENE, but the optimum swell for this break is NNE, so it’s not hitting it perfectly. It’s a maybe on a good day, but with that wind, it’s a tough call. I’d only eyeball this if you’re a seasoned local and the wind drops.

After that, Wednesday September 2nd looks even bigger—10 ft from the ENE with a 13-second period and a combined energy of 2838. That’s proper heavy. But the wind is strong and cross-onshore, rain showers are around, and the whole thing is rated as poor. It’s big, messy, and not a pleasant paddle. This kind of setup at a reef break with that much wind is more of a kite-surfing show than a paddle-in session. The onshore wind will make it lumpy and dangerous.

Don’t get your hopes up for the rest of the window. From Wednesday morning August 19th all the way through to Monday September 3rd, every single forecast calls for poor surf conditions or a complete zero. The wind is mostly cross or cross-onshore, and the swell is small and weak, with combined energy barely cracking 100 to 200. It’s flat, choppy, and lifeless. There’s a brief moment on Thursday afternoon August 20th with glassy conditions, but the swell is only 3 ft and the energy is a paltry 101. It’s surfable, but it’s barely a wave.

So, the standout here is the September 1st window, but it’s a shaky one. It’s the only time in the whole 16 days where the swell is significant and the energy is high. Everything else is a bust. That’s a brutal 13-day stretch of nothing. On the bright side, when the swell does show up, it’s got some punch, but the wind is the enemy. Keep an eye on the forecast, because if the wind shifts, that Tuesday could be a wild session. But as it stands, I’d be saving my wax for another week.
