Keaulanas Surf Forecast and Surf Report

Alright, Rusty here. Let’s chew the fat on what’s coming for Keaulanas.

First off, I gotta be honest—this 16-day run kicks off with a real dud of a first week. The early days are flat and frustrating. We’ve got a steady fresh breeze from the ENE, mostly cross-off, but it’s strong enough to ruin the tiny, short-period waves. The swell height hovers around 0.7m to 0.6m out of the SW or SSW, and the wave energy is low, barely cracking triple digits (432 down to 168). Most of the time, the data says “poor surf conditions.” It’s the kind of weather that makes you leave the board in the truck.

Then, around the middle of the second week, the ocean wakes up. Sunday, August 9th is the real deal. The morning brings a clean 0.6m S swell with a 19-second period, and the wind goes light offshore from the ENE. The combined energy hits 479—solid moderate. By the afternoon, it builds to 0.8m from the SSW, with a moderate offshore breeze, and the energy jumps to 672. The report says “expect very good surf conditions.” That’s the best window, no argument. That long period means the waves will have some punch and shape, and Keaulanas, being a beach and reef break, should handle it well. Water temp is about average for this time of year, nothing unusual.

The following Monday, August 10th, still has some size at 1.0m from the SSW, but the wind goes cross-off and the tide might be tricky. The energy is strong (707), but it’s called “marginal.” The Wednesday and Thursday after that, August 12th and 13th, show some clean 0.6m to 0.7m S swell with light cross-off wind and energy in the 350–400 range, which is surfable but not a standout.

The last few days, August 14th and 15th, the swell sticks around at 0.9m from the S, but the wind turns onshore or cross-shore, making it choppy and less inviting.

So, the bottom line: the first week is a gap of nothing. The only real standout is Sunday, August 9th. Mark it. The rest of the second week is a mix of small, clean moments and wind-affected slop. Keep your eyes on the forecast, but don’t hold your breath.

Rusty.
