The Lowdown
Alright, Rusty here. Let's get into it.
First off, the next couple of weeks are looking pretty flat and quiet for our spot. There's a big gap at the start with absolutely nothing to ride. We're looking at Thursday afternoon, the 27th of August, before the first even tiny ripple shows up, and that's just 0.7 ft. Honestly, it's a long stretch of nothing with only tiny, un-rideable bumps until we get into the first week of September. After that, there's more flatness until around the 10th of September when we finally see a bit of life.
The best of a bad bunch shapes up for Thursday the 10th of September. Anaehoomalu Bay A-Bay (Big Island) has a small long-period groundswell from the WNW rolling in at 1 ft with a period of 15 seconds. With glassy conditions in the morning, it'll be clean. The combined energy is weak at 98. It's not going to be classic, but it'll be the most surfable window in a very quiet period.
The afternoon of the 10th sees the best score of the whole run, with the same 1 ft WNW swell but enough energy to be just surfable, again with glassy wind. You'll have clean, tiny waves. But with it being a reef and point, that long period swell will wrap in nicely. Keep in mind, at this size, it's strictly beginner territory. The water is 82°, which is a touch warmer than average for this time of year.
After that, the 11th of September shows some small 2 ft W swells with a 13-second period and moderate combined energy (120-130), but the cross-shore winds and risk of t-storms will likely chop it up. It’s still going to be poor overall.
Honestly, if you’re desperate for a paddle, the 10th is the day to have a look. Otherwise, the whole 16-day window is a write-off.
