The Lowdown
Alright folks, Rusty here. Let’s see what’s happening in our corner of the Pacific.
Honokohau Harbour is a reef set-up, and honestly, it’s a bit of a slow starter. We’ve got a long gap of poor conditions right through the opening weekend and into the start of next week. The water is sitting at 81.3°, which is about average for this time of year, so nothing weird there.
The first real glimmer of hope shows up on Thursday afternoon, the 13th. The swell is only 3.6ft from the NNE, but the wind goes glassy. That’s a major positive. The wave energy is low though, at (133), so it’s not going to be pumping. It’s just a small, clean window.
But the standout, without a doubt, is Friday afternoon, the 14th of August. The swell jumps to 9.8ft from the NNE, and the wind is glassy. That’s a big one. The combined energy hits (993) – that’s strong stuff. This is a proper groundswell with a short period of 7 seconds, so it’s going to be a bit dumpy and fast. For a reef break, that can be a handful, but for experts, this is where it’s at. The water is still glassy, so expect clean, powerful, and challenging waves. Crowds are possible here, so get in early if you’ve got the skill.
After that, the swell drops off a cliff. The rest of the run looks poor again, with small, weak swells and onshore winds ruining the shape. There’s a tiny, glassy window on Monday morning, the 17th, with a 1.3ft WNW swell, but you’d be scratching for a ride.
So, call it. Friday afternoon, the 14th, is the one. Big, powerful, glassy. The rest of the window is a write-off.
