The Lowdown
Right then, let’s have a look at what’s on offer for Akabane Long Beach.
Straight up, I gotta be honest with you – the next week and a half is looking pretty grim. We’ve got a big stretch of poor to marginal conditions with hardly anything worth paddling out for. The first real chance for a surfable wave doesn’t show up until Sunday the 23rd in the morning, and even then, it’s just ordinary. The glassy conditions from the SSE breeze at 3 mph will make the surface clean, but the swell is small, only 2 ft from the SSW, and the period is a short 8 seconds. It’s surfable, but nothing to write home about.
After that, Monday the 24th brings a bit more size. The morning sees a 6 ft SSE swell, but the wind is a light cross-onshore, so it’ll be a bit of a bumpy ride. The energy is strong, with a combined energy of 2315, but it’s a long-period groundswell at 18 seconds, which can make a beach break close out a bit straight. The afternoon gets bigger, up to 8 ft, but it’s onshore and messy.
Now, Tuesday the 25th is a real standout… but only for the experts. We’ve got a solid 12 ft swell from the SSE, with glassy conditions in the morning. The water temp is about 81°, which is pretty average for this time of year. The wave energy is massive, over 4900, but the swell is just too big for this spot. It’s a beast for the experienced crew only.
The next few days stay big and messy. Wednesday the 26th has 8 ft swell, but with a thunderstorm risk and cross-onshore wind, it’s not going to be pretty. The wind picks up heavy through Thursday and Friday, ruining any chance of clean waves.
The real excitement, and the absolute best on offer in the whole 16-day window, is Thursday the 3rd of September. That morning, the stars align. We’ve got a glassy, calm surface with zero wind, and a huge 15 ft swell from the ESE. The period is a very long 19 seconds, with a combined energy of 13625 – that’s some serious power. This is a groundswell of epic proportions, but the size means it’s strictly for the experienced. The swell direction is a perfect match for the break’s optimum. It’s a powerful, clean, long-period beast. The afternoon stays huge, 20 ft, but the onshore wind will ruin it.
So, to sum it up: don’t bother for the first week. The one true highlight is that Thursday the 3rd of September morning session. It’s a long way off, so the forecast could change, but if it holds, that’s the one to circle on the calendar. The rest of the second week fades back into choppy, lumpy conditions.
