The Lowdown
Alright, folks, Rusty here again. I’ve had a look at the coming swell window for Anaehoomalu Bay (A-Bay) and I gotta tell you, it’s looking pretty flat and quiet for the next couple of weeks. This is a reef and point setup that usually needs a good dose of WNW groundswell to wake up, but right now, there’s just nothing doing. The water temp is sitting at 81.9°, which is about a degree warmer than normal for this time of year, so it’s a bit on the toasty side, but that doesn’t mean much when there’s no waves to enjoy.
The first real chance of anything rideable is a long way off, and even then, it’s not great. From Friday 28 August right through to the end of the first week of September, we’re looking at a total blank. Swell heights are barely a ripple—0.3ft to 1ft at best, with periods all over the shop, from 7 seconds up to 18 seconds, but the energy is just not there. The combined energy values are pitiful, mostly in the single digits or low teens (12, 11, 9, 35 for a brief moment), and even when the period gets long, like 18 seconds on the 29th, it’s only 0.3ft. That’s not surf, that’s a lake. The wind is mostly cross or light cross-onshore from the north, so nothing is lining up for A-Bay’s preferred WNW direction.
We finally see a tiny pulse on Monday 7 September morning with 1ft swell from the SW at 15 seconds, and combined energy of 34 (weak). Still poor surf conditions, though. Then on Thursday 10 September morning, we get 1ft from the SW again, 16 seconds, with energy up to 65 (still weak). The wind is a moderate cross-shore from the SSW, so it’s choppy. Not worth paddling out.
The most promising looking window is way out there on Saturday 12 September morning: 1ft from the WNW at 14 seconds, with combined energy of 68 (weak). It’s cross-onshore from the north, so not clean, but at least the direction is correct. Then Saturday afternoon the wind goes glassy, but the swell drops to 1ft from the WNW at 12 seconds, energy 27 (weak). It’s a tiny, glassy dribble. For a true standout? There isn’t one. The best I can say is that Saturday 12 September afternoon might be a super small, clean session for a longboard or a foiler, but don’t expect much. The crowds are listed as “sometimes” at A-Bay, but with surf this poor, you’ll have the place to yourself.
Because the swell is so small and the quality is consistently poor, and it’s a reef and point setup, this isn’t even interesting for kite surfing. Just a flat spell. Hang in there, the forecasts can change, but for now, it’s a long wait.
