Keaulanas Surf Forecast and Surf Report

Alright, surfers, Rusty here. Let's have a look at what's on the menu for Keaulanas. This spot is a consistent beach-and-reef setup that's wide open to the swell, and it likes a good W direction, though we're seeing a lot of S and SSW energy in this window.

The water temperature is sitting at a warm 82° right now, which is about 1° above the long-term average for this time of year, so it's feeling pretty much normal for the season.

We kick things off with a bit of a wait. The first real action starts on Wednesday the 26th of August. The afternoon brings a 3 ft south swell with a very long 18-second period, pushing a moderate wave energy of 530. The wind is offshore from the ENE at 16 mph, so the surface will be clean. It's a small but promising start, though the conditions are a bit marginal.

The standout here is Thursday the 27th of August. The morning has a 4 ft south swell, 17-second period, and a solid wave energy of 792. The wind is still offshore from the ENE at 16 mph. This is the best of the first week—clean, punchy, and with that long-period energy wrapping in. The afternoon holds at 3 ft and 625 energy, also with offshore winds. This is the one to circle.

After that, things drop off. Friday the 28th is smaller at 3 ft with a shorter 14-second period, and the wind goes cross-offshore. The weekend is a write-off. Saturday and Sunday see the swell drop to 2-3 ft, periods are short, and the wind is cross-off, with poor surf conditions forecast. There's a gap of poor to marginal surf from Friday the 28th through to the 31st of August.

We get a slight flicker of hope on Monday the 31st of August and Tuesday the 1st of September with small 2 ft SSW swells, but the wave energy is still modest and the quality is marginal. The real return to form looks like Wednesday the 2nd of September. The morning sees a 3 ft south swell, 16-second period, with offshore winds again. The energy is moderate at 366, and the conditions are clean. This holds through Thursday the 3rd of September with 2-3 ft south swell and mostly clean cross-off winds.

The next true standout is Friday the 4th of September. The morning is glassy—wind from the south at just 3 mph, zero ripples, and a 3 ft south swell. It's small, but perfection is on the cards. The wave energy is 231. Saturday morning the 5th also has glassy conditions, though the swell drops to 2 ft. Saturday afternoon brings a 2 ft SSW swell but with a very long 18-second period and glassy winds, pushing a wave energy of 288.

The surf stays small but rideable into the second week, with a few good sessions on the 8th and 9th of September. The 10th of September sees the wind picking up to a fresh 22 mph offshore, which will keep the surface clean, but the swell is tiny at 2 ft, so it's more of a skippers' session.

Overall, for Keaulanas, the clear winner is Thursday the 27th of August for the best combination of size, period, and clean offshore wind. The glassy conditions on the 4th and 5th of September are also a beautiful treat for the small-wave crew. Don't hold your breath for the weekend in between.

Rusty, signing off.
