The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Anaehoomalu Bay.

Right off the bat, I gotta be straight with you – it’s looking lean for the next week or so. We’re kicking off with a long dry spell where there’s just nothing doing. From September 1st right through to the morning of September 6th, the ocean is basically asleep. You’ll see a lot of zeros in the energy department. That’s a solid five days of flatness, so don't bother rushing down there.

Finally, on the afternoon of Sunday the 6th, a little pulse of life shows up. The swell is tiny at 2ft from the SW, with a period of 10 seconds. The wave energy is very weak (108), and the water temperature is 82° – that’s a touch warmer than usual for this time of year, about a degree above normal, but that’s about all the excitement we get. It’s glassy, which is a major positive for the surface, but honestly, that’s about the only thing going for it. It’s surfable, but very ordinary.

The real tease comes on the 8th of September. Tuesday morning brings a jump in swell height to 4ft from the WSW with a very long period of 14 seconds, and the combined energy hits a solid moderate 522. By Tuesday afternoon it builds further to 6ft from the same direction, the period stays long, and the energy jumps into strong territory at 1068. That’s the standout of this whole outlook. That long period groundswell is going to have some real punch, and it’s the one window that looks genuinely interesting. The catch? The wind is onshore or cross-onshore from the West, which will mess with the surface. This is a reef and point setup at Anaehoomalu Bay (A-Bay), and the optimum direction is WNW, which the WSW swell is close-ish to. If you’re an intermediate or better, that Tuesday afternoon window could offer some decent, powerful lines, but don’t expect perfection in the conditions. The opening few days of the second week still show some swell energy, but mostly in the 2ft to 4ft range, with some glassy moments on the 9th afternoon, but nothing that hits the same peak as that Tuesday.

Overall, the 8th of September is the only real highlight in this 16-day outlook. Everything else is either flat or just small and average. For a spot that’s fairly consistent, this is a quiet run, but it’s worth keeping an eye on that Tuesday.
