Keaulanas Surf Forecast and Surf Report

Alright folks, this is Rusty checkin' in from the beach. We've got a look at the next stretch for Keaulanas, a beach and reef setup that's usually consistent. Right now the water's sitting at a balmy 81°, which is pretty average for this time of year, nothing to write home about. The first few days are looking good but we gotta work through a bit of a slow start.

The pattern is set to kick off on the afternoon of Monday, 14 September. We're seeing a small, long-period groundswell from the SW at 2ft with a 22-second period. That's some serious juice for such a tiny wave, and the combined swell energy is weak (275). The surf will be clean with a light cross-off breeze, so it'll be fun if you're on a log.

The real highlight arrives on Tuesday morning, 15 September. Glassy conditions, zero wind, and a bump in swell to 3ft from the SSW with a 20-second period. The energy jumps up to moderate (531). That is the best session of the whole forecast – clean, long lines, and you won't be fighting the wind. Tuesday afternoon stays glassy with a 2ft SSW swell (422), still very rideable.

Wednesday the 16th and Thursday the 17th hold clean, offshore conditions both mornings. Swell hangs around the 3ft to 3ft range from the SSW, period dropping to 16-18 seconds, with moderate wave energy in the mid-500s. Afternoons get a bit of a breeze kicking up, but the mornings are the time to paddle out.

After that, we hit a real lull. From the afternoon of Friday the 18th all the way through to Monday the 21st, the wind switches to a persistent cross-off with moderate breezes. Swell stays around 3ft to 3ft, but the conditions get marginal, and the scores drop off. By the afternoon of Sunday the 20th, it's straight-up poor surfing, and that continues for several days.

The forecast points to a bit of a comeback on Monday morning, 21 September, with a fresh 3ft S swell at 14 seconds and moderate offshore winds (434 energy). It's a cleaner window, but still not the glassy perfection of that Tuesday. Then from Tuesday the 22nd right through to the end of the forecast window on 29 September, it's a grim run. Fresh breezes and poor conditions dominate most days. There are a few small pockets – like the afternoon of Monday the 28th when a light cross-off wind and a 2ft SSW swell (433) bring back some "good surf" potential – but these are fleeting.

Overall, if you can get out on the morning of Tuesday the 15th, do it. That's the standout. The rest of the run is mostly a struggle with wind and marginal waves. The next solid-looking window after that is the morning of the 28th, but that's over a week away and less certain. Keep your eyes peeled, but don't hold your breath.

Rusty, signing off.
