The Lowdown
Right, listen up. Rusty here. Gotta be straight with you – the surf over the next sixteen days is looking pretty grim for Laniakea Reef and Holtons. We’re talking about a long, flat stretch, so if you're itching for a wave, you might want to temper those expectations.
The first week and a half is a write-off. From August 9th through the 20th, there’s just nothing doing. The swell is tiny, mostly under 1ft, and the energy is weak. The wind is cross-offshore, so the water’s clean, but with waves this small, it’s just not worth paddling out. You'd be sitting there bobbing around with nothing to catch. The period is all over the place, but it doesn’t matter when there’s no size to push through. It's going to be a long stretch of clean, flat water.
Now, for the one standout in this whole window, and it’s a long way off, so mark your calendar for Friday, August 21st. The swell finally shows a pulse, with waves building to about 2ft. More importantly, the energy jumps to a moderate 176 in the morning and 152 in the afternoon. There’s a long-period groundswell rolling in from the southwest with a period of 17 seconds, which for this spot is a real sign of life. It's nothing epic, but compared to everything else, it's a proper surf. The wind is light and offshore from the east at 6 mph, which should keep the face clean. Even the water temperature is sitting right at 80°, which is just about normal for this time of year.
So, if you can wait it out, the 21st is your day. It won’t be big, but it’ll be clean and have some push. For a spot that’s been flat for a week and a half, that’s a win. After that, it looks like it fades back out to nothing again for the rest of the window.
This is Rusty, signing off. Keep the faith.
