The Lowdown
Alright, Rusty here. Let’s break it down.
The first week or so at Akabane Long Beach is pretty much a total loss. The wind is a constant pain, coming cross-onshore from the ESE, making the surface choppy and messy. There’s some swell, but it’s just not clean. The combined energy reads moderate on Saturday, hitting 462, but it’s all chop.
The only tiny window in the early days is Wednesday the 19th morning. The wind goes completely glassy, dead calm. You’ve got small 3ft swell from the ESE at 8 seconds. The combined energy is a weak 118. It’s surfable, but very ordinary. The water’s at 82°, which is average for this time of year, nothing special.
From Thursday the 20th through the 23rd, it’s a big gap. Small, weak, and poor conditions. Nothing worth paddling out for.
Now, the real action is way out in the forecast. The 24th of August brings a big pulse of long-period groundswell from the SE. Monday morning shows 8ft swell with a 17-second period, and the combined energy jumps to 3291 – that’s strong. The report says it’s marginal with questionable tides, and the wind is onshore from the SSE. Not perfect, but powerful.
The real standout is Tuesday the 25th. The morning is glassy, no wind. The swell is a solid 12ft from the SE, with a 16-second period. The combined energy is a massive 5464. This is big, heavy, very long-period groundswell. The wind and tide are favorable, but the report warns the swell is predicted to be too big for this break. This is for expert surfers only. The waves will be heavy and unforgiving. The afternoon turns onshore, so the morning is the only window.
After that, the 26th and 27th are blown out or too big with poor conditions. The 28th and 29th drop back to small, weak surf with onshore winds. The final day on the 30th has a 2ft swell from the ESE with a very long 16-second period, but it’s cross-onshore and weak.
Bottom line: The first week and a half is a no-go. The only real shot at something special is the morning of the 25th, but it’s a beast for experts only. The 24th might offer a less intense but still challenging option. Don’t hold your breath for the rest.
Rusty.
