The Lowdown

Alright, this is Rusty. Let's have a look at what's on offer for our local stretch.

Right off the bat, I gotta be straight with you – it’s a tough run ahead for Anaehoomalu Bay (A-Bay). This is a reef and point setup that usually needs a decent push from the west-northwest, but we’re looking at a long, frustrating stretch of tiny surf.

Starting now, we're looking at a real flat spell. For the first week and a half, through to about the 16th of August, it's pretty much a write-off. The swell is consistently below 1 ft, which is just not enough to push a wave face. You’ll see a few ripples, but nothing you’d paddle out for. The wind is often light, which is a tease, but the wave energy is just not there. The combined energy is barely registering, often in the single digits or low twenties.

Then, around the 17th of August, things start to change. On Monday afternoon, we finally see a bit of life. The swell bumps up to 1.0 ft from the WNW with a solid 14-second period – that's some long-period groundswell energy. The combined energy climbs to 84, which is getting into a modest range. The winds go glassy. It's described as "surfable waves but very ordinary conditions". It’s not going to be a classic, but after a week and a half of nothing, a knee-high, glassy wave with that much period might be the only thing worth a splash. The crowd factor is "sometimes" here, so you might have some company for those tiny nuggets.

Tuesday the 18th is similar in size but the wind gets a bit messy, and it’s not as clean. The real interesting one pops up on Wednesday the 19th. That afternoon, we get a 1.0 ft swell from the SW with a whopping 18-second period, and the combined energy hits 76. It’s still small, but the direction is a bit different for A-Bay, and with that long period, the reef might just focus that energy into a clean little bank. Winds are glassy again. This is your best chance for a sneaky, clean wave, but it’s still only a small, long-period swell that works best at points and reefs.

Look, there’s nothing big on the cards. The standout moment is that Wednesday 19th afternoon – the cleanest, most promising combo of the whole 16-day run. The first week is a total gap with zero recommendations. After that, it’s a couple of small windows of opportunity in the second week, but nothing to get too excited about. The water temp is a normal 81° for this time of year.

Stay patient. The good news is, forecasts can change, and this place can turn on a dime. But for now, it’s a waiting game.

Rusty.
