The Lowdown
Alright folks, Rusty here. Let’s get into it.
Well, I gotta be straight with you – this 16-day window for Anaehoomalu Bay (A-Bay) is a real tough one. Honestly, the whole period is a flat spell. There’s nothing breaking that’s worth paddling out for. The ratings are all zeros across the board, and every single session is flagged as "poor surf conditions." So, we’re looking at 16 days of flat water. It’s a bummer, but sometimes that’s just how it goes in this area. It’s a consistent break normally, so this is a quiet run that feels a bit longer than usual.
The first chance we see on Wednesday morning, August 26th, is just a tiny 0.7 ft ripple from the West. Combined wave energy is a measly (9), so you’re basically bobbing around. The water temp is a touch warmer than normal at 82°, about 2° above average, so it’s a nice bath, but not for surfing.
We do get some glassy conditions on Thursday afternoon, August 27th, with a 0.7 ft swell from the North, but it’s a short period at 8 seconds. The energy is even weaker (5). It’s pretty, but it’s not surfable.
There are a few glimmers of glassy water later on, like the 1.0 ft swell from the West on Sunday, September 6th, with a 12-second period and energy climbing to (25), but it’s still too small. The best looking window in the whole forecast is the very end, on Thursday, September 10th. We see a 1 ft swell from the WNW with a solid 12-second period, and energy hits (87) in the morning. The wind is light cross-onshore, but it’s still only 1 ft. It’s a step in the right direction, but it’s not a green light to paddle out.
So, there’s no standout. No best on offer. It’s a full 16-day dry spell. Stash the board and check back in a few days; forecasts can change.
Rusty.
