Kewalos Surf Forecast and Surf Report

Alright, Rusty here, looking at the charts for the next couple of weeks. Water temps are running at a pretty normal 81°F, so that’s one thing we don’t have to complain about.

The whole 16-day window is centered on Kewalos (Oahu). It’s a reef, so it needs the right angle to work. The pattern is looking spotty. We start off on Wednesday the 12th of August with a clean little south swell, only about 3 feet with a super long 18-second period. The energy is weak at 911, and it’s only a marginal day. It’s there, but it’s not calling your name.

Thursday and Friday stay clean with cross-off winds, but the surf is small, and by Friday the 14th, the period drops to 8 seconds, giving us weak, short-period windswell. Not worth rushing out for.

The weekend of the 15th and 16th of August gets chunky. A big east-northeast swell pushes in, hitting 13 feet on Saturday afternoon with a strong energy reading of 2563. But the wind is blowing a steady 31 mph from the east-northeast. That is expert-only, heavy surf. It’s going to be big, messy, and dangerous. For the average surfer, this setup looks more interesting for kite boarding than paddling out.

After that, it goes flat and quiet. From the 17th through the 26th, we get a long stretch of little east-northeast slop and some tiny, clean south groundswells that are too small to ride. A few mornings, like the 19th and 20th of August, show some long-period south swell, but it’s only about 2 feet and weak.

If you’re holding out for the best window, it’s Thursday morning, the 27th of August. It’s a way-off call, but the models show a clean 2 to 3-foot south swell with a 13-second period and that steady cross-off wind making it look clean. It scores the best of the whole run at a 2 out of 10. It’s small, but it’s the best we’re gonna get here. Don’t expect fireworks, just plan for a long, quiet wait.

Forecasts can change for the better, but right now, this is a slim run.

Rusty.
