The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Anaehoomalu Bay, also known as A-Bay. Straight up, this is a tough stretch. For the next week and a half, the surf is flat to tiny, so don’t bother rushing down there with your shortboard. The one spot with potential is a reef and point setup, and it’s fairly exposed, so it can catch something. The water temp is sitting at 80.8°, which is about average for the time of year, so it’s comfortable.
We start from August 1st. The first few days are a write-off. Swell heights are a pathetic 0.7ft to 1.0ft, and the combined wave energy is barely a whisper, reading a weak 29 on the 1st. It stays like this for a solid week. Winds are mostly cross or onshore, so don’t expect any magic. There’s a moment on Sunday the 2nd afternoon with glassy conditions and zero wind, but the swell is still 1.0ft from the north with a short period of 9 seconds – you’d be bobbing around on a lake, not surfing. This pattern of tiny, poor surf drags on right through to August 8th.
There is a glimmer of hope around the 9th and 10th, but it’s barely worth mentioning. On Sunday the 9th afternoon, we see a bump in the swell to 1.3ft from the WNW with a period of 15 seconds. The energy jumps to 78 (still weak), and it’s glassy with light wind. It’s still tiny, but it’s the first time the conditions are clean. The best bet in this whole outlook, and I mean the only one that gets close to being a standout, is Saturday the 15th. The swell finally pushes up to 3.3ft from the west, with a period of 15 seconds. The combined energy hits 435 (moderate) and the wind is calm and glassy for the afternoon. This is the one session that might give you a few clean lines if you’re patient. The waves will be small and beginner-friendly, not a barrel fest.
After the 15th, the swell hangs around the 3.3ft mark with that long period, but the wind turns cross-onshore again on the 16th, so it won’t be as good. Starting off rough, but there is one decent window on the 15th.
