Kewalos Surf Forecast and Surf Report

Alright, Rusty here. Let's get into it.

Right off the bat, this 16-day window is a tough one for Kewalos. We've got a long stretch of nothing much to get excited about. The first real sniff of surf isn’t until Sunday the 9th, and even then, it’s a bit of a struggle.

Sunday Afternoon (August 9): We're starting with a 5 ft swell from the ENE, but it's side-offshore and the period is a short 8 seconds. The combined energy is only 566, which is pretty weak. The water is a warm 81°, about average for this time of year. Honestly, it's marginal at best.

Monday through Thursday (Aug 10-14): A real flat spell here. The swell drops off to around 3-5 ft, but with poor conditions and scores of zero for most of it. There's a brief spike of long-period energy on the 12th (18 seconds, 903 energy) but the swell height is only 3 ft, so it's more of a tease than anything. The side-offshore wind stays consistent, but the size and quality just aren't there.

Friday Afternoon (August 14): A bump of 6 ft from the ENE shows up, but it's still just marginal. The energy picks up to 871, but it's coupled with that short 8-second period. Still not the one we're waiting for.

The Standout: Sunday Morning, August 16th
This is the one. The one that makes the waiting worth it. We've got a solid 15 ft swell from the ENE, a period of 13 seconds, and the wind is pure offshore from the north at just 6 mph. The combined energy is a whopping 6695 – that's serious power. This is expert territory, no question. Over 8 ft of wave height, so it's only for those with the skills and the nerve. The light offshore wind will have it absolutely grooming. This is the true highlight of the entire forecast. It’s not a beach break, it's a reef, so the long-period groundswell will wrap in nicely. Expect it to be on.

Sunday Afternoon (August 16): The swell drops off dramatically in the afternoon, down to 2 ft from the south. The energy crashes to 287. A completely different story.

The Second Week (Aug 17-24):
The run-up to the 16th is the peak. After that, we're back into a long, disappointing stretch. From the 17th through the 24th, it's a non-stop parade of poor surf conditions and zero or near-zero scores. Numerous days show ENE swell between 4 ft and 7 ft, but the wind is crossed-up or onshore, messing with the shape. The period stays short, mostly 6 to 9 seconds. The energy values are moderate at best, usually between 341 and 914. The morning of the 24th might have a slightly cleaner look at 7 ft, but with a short period and cross-off wind, and a score of just 1, it’s hard to recommend.

In short: The only true standout is the morning of Sunday, August 16th. That's your window for big, clean, expert-level waves at Kewalos. The rest of the 16 days? A whole lot of waiting and watching.

Stay patient, friends.
