Kahului Harbor Surf Forecast and Surf Report

Alright folks, let's be real. The next two weeks are looking like a total grind. We've got a long stretch of junky, cross-onshore slop that's gonna test your patience more than your skill. Don't get your hopes up for anything decent until we push through a solid week of this mess.

The first few days, starting Sunday the 9th, are a total washout. We're looking at chest-high, short-period windswell from the ENE, around 5ft, with a period of just 8 seconds. The wind is gonna be blasting sideways all day, making it lumpy and hard to find any kind of rhythm. The energy is weak too, only coming in at 278. Just leave the board in the car.

This pattern sticks around through the week. Monday the 10th and Tuesday the 11th are more of the same, just smaller, in the 4-5ft range, with the period dropping to 7 seconds. Still cross-shore and cross-on winds, still weak energy (198-262). It's not even worth paddling out for a grovel. We're in a holding pattern of poor surf conditions, people.

The swell starts to pick up a bit into Friday the 14th, but the quality doesn't improve. The energy jumps to a moderate 381-465, and we're seeing waves around 5-6ft, but it's still that short-period ENE windswell and the wind is still ruining any chance of a clean face.

Now, here's where it gets interesting, but not in a good way. The weekend of the 15th and 16th sees a serious pulse of energy arrive. The combined energy shoots up to a strong 1603 on Saturday morning, hitting a whopping 2911 by the afternoon. Swell heights are pushing 8-10ft. The period stretches out to 11-13 seconds, which means there's some real power behind it. But here's the catch – this place is a reef break, and with that much juice and that long a period, it's going to be a washing machine for all but the most experienced. On Saturday, the wind is still cross-on and just adding to the mess. By Sunday the 16th, we get some onshore wind from the N/NNW, and the guidance notes the swell is predicted to be too big for the break. This is definitely expert-only territory, and even then, it looks like a close-out. Not the kind of day to be a hero.

Things finally start to settle down after that. Monday the 17th sees the swell drop to a more manageable 7ft, and we finally get some offshore wind in the afternoon. The energy is still moderate at 395, and the conditions are described as clean for the first time. But it's still only a 2 out of 10 for surf quality. It's like the ocean just took a deep breath, but still isn't ready to give us anything good.

Then we hit the doldrums. From Tuesday the 18th through the rest of the window, it's mostly small, weak, and inconsistent. Tuesday morning is glassy with a tiny 2-3ft wave, but the energy is gone (164) and it's just not going to be worth the paddle. The rest of the week is back to poor surf conditions with weak, short-period slop. There's a small pulse around the 22nd and 23rd with energy in the 285-601 range, but it's still that same messy cross-on wind.

So, to be straight with you, there are no standouts in this two-week stretch. The only real spike in size and power is that weekend of the 15th-16th, but it's way too big and blown out for this spot to be any fun.

If you're desperate, the Monday morning of the 17th is your best bet – it's the only time we see any offshore flow and the swell drops to a semi-reasonable size, but it's still marginal. You'd be paddling out for a few sloppy ones, not a session to remember. It's a long stretch of nothing.

The water temp at Kahului Harbor is about average for this time of year, sitting at 80° with a normal anomaly, so at least you won't need a hood.

Keep the board in the bag, this is a good time to work on your waxing skills.
