The Lowdown
Alright, you’re locked on to just one spot this time: Akabane Long Beach. Let’s get into it.
Right now, Akabane Long Beach is pretty sleepy. The first bit of surf worth paddling for comes Friday morning, August 28, with a small 4ft swell out of the south at a short 7 seconds. The combined energy is weak (230), so it ain't got much punch. The wind is light and offshore, making it clean, but it's just a soft little wave. Not worth driving for unless you’re desperate for a paddle. Water temp is a toasty 84°, which is about 2° warmer than normal – that’s noticeable, feels like bathwater.
The real tease comes later. From August 31 through most of the first week of September, the surf is physically there, but the wind is relentless – mostly onshore or cross-onshore at 19 mph and more. Swells build to 5ft to 6ft, with combined energy climbing into the 500-800 range, so there’s power, but it’s all blown out. Rotten conditions. You'd be better off taking the time off.
There’s a little flicker on Sunday, September 6 in the afternoon. A 5ft south swell at 11 seconds rolls in, and the wind swings offshore (NW, 12 mph), with strong combined energy of 941. That's a standout window – clean, solid, proper wave shape. That’s your best bet if you can wait. Monday morning, September 7, still has some cross-off wind and a similar 6ft south swell, but it’s more marginal.
Then things go quiet and windy again until Thursday, September 10. That morning, a very long-period groundswell arrives from the SSE at 8ft and 14 seconds, with combined energy through the roof at 2573. The wind is light and cross-offshore. This is a serious swell – but for a beach break, that long period may make the waves wall up and close out. Still, for experienced surfers, it’s the best on offer in the whole 16-day window. The following days see even bigger swell (10ft to 12ft), but the combination of strong onshore wind and size pushing over 8ft means it’s too big and messy for most.
Crowds at Akabane Long Beach are “often” an issue, so expect company on those rare clean days, especially September 6 and September 10. Take what you can get.
A few days with no real chance in the first week, but the second week offers that one Thursday stand-out for the crew who can handle size.
