The Lowdown
Alright, this is Rusty. Let’s be straight with you – the outlook for the next sixteen days at Honokohau Harbour is a bit of a bummer, if I’m honest. We’re looking at a long stretch of pretty ordinary conditions, with very few windows where you’d actually want to paddle out.
The first real chance of anything surfable doesn’t show up until Sunday afternoon, the 9th of August. Even then, it’s not exactly firing. We’ve got a tiny 2ft swell from the SSW, but the saving grace is that it goes glassy. That’s about the only positive, with the combined energy sitting at a weak 141. It’s surfable, but very ordinary.
The rest of the first week and into the second is a write-off, with persistent cross-onshore winds and tiny swell. The water temp is sitting at 81°, which is a touch warmer than normal for this time of year.
The best we really get to talk about is the Monday and Tuesday of the 17th and 18th of August. It’s a long way off, so don’t bank on it, but the models are showing a bit more size. On Monday the 17th, we’re looking at 5ft swell coming from the NNE, but with a short period of only 7 seconds. That’s weak, windswell energy, and it’s going to be pretty crumbly and messy. The combined energy hits 360, which is moderate, but those short intervals mean the waves will lack any real power. It’s still marginal, and the wind is cross-on, so it’s not clean. Tuesday the 18th is similar, with 5ft from the NNE and an 8-second period, still marginal and cross-on. Not a standout.
Honestly, nothing here is a standout. For a consistent reef break like Honokohau Harbour, it’s a frustrating run of small, onshore, and mediocre surf. The only real advice I can give is to keep an eye on the glassy window on Sunday the 9th if you’re desperate for a splash, but don’t expect much.
Rusty.
