Kewalos Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for the next couple of weeks.

Right off the bat, the first half of the outlook is a bit of a mixed bag. We’ve got some solid energy in the water, but the wind is going to be a real problem. The pulse of swell that hits Monday morning the 7th brings a powerful 8ft swell from the ENE with a moderate 12-second period, and the combined energy is a very strong 2716. But the wind is a fresh 19 mph cross-shore from the ESE, and with a risk of thunderstorms, it’s going to be lumpy and tough. That afternoon, the wind picks up to 22 mph and goes cross-on, making it poor. Tuesday the 8th isn’t much better; the morning has a 8ft SSW swell but the wind is onshore and lumpy. The afternoon drops to 5ft but it’s still cross-on and choppy. For a spot like Kewalos, which is a reef break for advanced surfers only, these conditions are a pass.

The real standout, the one that’s worth your time, is going to be Wednesday afternoon, the 9th of September. We get a clean 3ft SSW swell with a long 13-second period, and the wind drops to a light 6 mph and goes cross-off. The combined energy is a moderate 563, but that clean, light wind on a reef like Kewalos is going to make for some really fun, lined-up waves. The water temp is 81°, which is bang on average for this time of year, so no surprises there.

We then get a long stretch of smaller, cleaner days, but nothing really firing. Thursday the 10th stays clean with a 5ft ENE swell, but the period is a short 7 seconds, so it’ll be a bit weak and crumbly, with combined energy around 656. Friday the 11th through Sunday the 13th are all clean but tiny, with swells under 4ft and energy dropping below 600. By Monday the 14th, the swell drops to just 1ft, though the period is a very long 23 seconds. That’s a groundswell, but for a reef like Kewalos it’s just too small to do anything. The following week is a write-off—from Monday the 14th all the way through to Tuesday the 22nd, the surf is consistently weak, mostly under 3ft, and the wind is a fresh to strong breeze from the ENE. It’s clean, but with combined energy values dropping as low as 66, it’s not going to be worth paddling out. The best you could hope for in that second week is a small, clean wave on Tuesday the 15th with a 2ft swell and long 20-second period, but it’s still marginal.

In short, if you’ve got a board, mark Wednesday afternoon the 9th on your calendar. That’s the window. The rest is either blown out or too small to bother with. There’s a big gap of poor conditions from the 10th right through the 22nd, so don’t expect much.

Rusty.
