The Lowdown
Alright, Rusty here. Let’s have a look at the next couple of weeks for Anaehoomalu Bay (A-Bay).
To be straight with you, the outlook is pretty grim for a long stretch. Starting now and right through the first week of August, we’re looking at a real dead spell. For days on end, there’s zero swell showing and just flat, poor conditions. It’s not until Thursday, August 6th that we finally see something worth paddling out for, and even then it's barely a whisper.
The best of a quiet bunch comes on Thursday, August 6th, both morning and afternoon. We’ve got a tiny 1.6 ft swell rolling in from the west, with a long 14-second period – that’s proper groundswell, which can groom up nice for a reef setup like A-Bay. The wind is glassy, which is a huge bonus, and the water is sitting at 80.1°F, which is about average for this time of year – no warm or cold shocker here. The combined energy is moderate, reading 107 and 106, so there’s a little bit of life. It's ridiculously small though, so not for anyone looking for power. Saturday, August 8th sees a slight bump to 2.0 ft from the west, also with glassy wind in the morning and combined energy up to 153, which is still moderate.
Overall, there are no standouts here. The week ahead is a write-off. If you’re desperate for a splash, the glassy mornings on the 6th and 8th of August are your only real chance to get wet, but keep the expectations low. It’s the kind of small, clean surf that suits a longboard or a funboard if you just want to be out there. Crowds are sometimes an issue here, but honestly, on this kind of tiny swell, it’ll be quiet.
