Right, grab a coffee, settle in. I’m Rusty, and I’ve been staring at the charts for your stretch of coast. Let’s be straight with each other: the next couple of weeks are going to test your patience. We’re looking at a long, flat spell before anything really gets going.
We’re talking about Anaehoomalu Bay / A-Bay, a reef and point setup that’s fairly exposed and likes a good WNW swell. Right now, the water temp is sitting about average for the time of year.
The outlook starts quietly. This weekend—Saturday the 11th and Sunday the 12th of July—is a write-off. Tiny waves, maybe 1ft to 2ft, with a period around 13-14 seconds, but the wind is all wrong. Cross-shore and cross-on breezes mean the little bumps we do have are chopped up and messy. Combined swell energy is weak (around 112 down to 28). You’re not missing a thing.
Monday the 13th offers a tiny glimmer. We get a pulse from the SW, still only 1ft, but the period stretches out to a very long 15 seconds. The morning sees a light cross-offshore breeze, cleaning things up nicely, and the combined energy picks up to a moderate 104. It’s surfable but very ordinary. Later that afternoon the wind goes glassy, but the swell drops away again. Not a standout, just a little break in the boredom.
Tuesday the 14th is a head-scratcher. Swell from the west picks up to 2ft-2ft with a proper long period hitting 19 seconds. Combined energy jumps right up (251-267). That’s real groundswell energy. The problem? It’s blowing straight onshore from the west. The wind is going to trash that potential. It’s a marginal call at best. Wednesday the 15th is similar: 3ft from the west, 15-16 second period, strong energy (302-310), but onshore and cross-on winds keep things messy. It’s frustrating.
The first proper standout comes late in the first week. Thursday the 16th of July afternoon. We’ve got a solid 3ft of west swell rolling in with a 15-second period (moderate combined energy of 272). But the kicker is the wind: it goes glassy. Dead flat, offshore glass. This is the cleanest, most inviting window in the whole run. If you can be out there that afternoon, do it. It still might be a little inconsistent on a point, but for the size, those conditions are a treat.
Friday the 17th holds some clean, glassy conditions in the morning and afternoon (2ft-2ft, 14 second period), but the energy drops off to moderate-low (203-146). It’s surfable and ordinary. After that, we’re sliding back down. Saturday the 18th sees the swell shrink again to 2ft, and while there’s a glassy moment in the afternoon, it’s small. Then from Sunday the 19th all the way through to Saturday the 26th of July, you’re looking at a massive dry spell. The swell barely tops 1ft, and for days on end, combined energy is zero or under 50. There’s some glassy mornings in there, but no wave to push you. It’s essentially flat.
So, to wrap it up: Thursday afternoon the 16th is your true window—clean, glassy, with some proper energy behind it. The rest is a waiting game. The breaks here can be quiet like this, so don’t let it get you down. Forecasts can change, but for now, that Thursday afternoon is the one to circle.
Rusty.
