The Lowdown
Alright, let's get into it. The next couple of weeks are gonna be a real mixed bag. We start off with a whole lot of nothing, so don't rush out the door.
The water temp at Akabane Long Beach is 81°F, which is pretty much par for the course this time of year. No surprises there.
So, for Thursday the 20th and Friday the 21st, it's honestly flat and useless. We're looking at ankle to knee-high slop, 1 to 3 feet, with barely any energy behind it. A few of the mornings are glassy, but there's just nothing to surf. You'd be better off waxing your board and just looking at it.
The weekend, the 22nd and 23rd, stays pretty grim. The swell stays tiny, around 2 to 3 feet. The south winds start to put some chop on it. There's a little more energy on Sunday afternoon, but the period is a short 8 seconds and it's blowing onshore. It's still not worth the paddle.
The 24th is when things start to pick up, but it's going to be a mess. The swell jumps to 7 feet on Monday morning and 8 feet by the afternoon from the SSE, with a long 16-second period. There's some serious power in the water now. But the winds are onshore and the surface will be choppy. It's big and strong, but not clean.
Tuesday the 25th is the one. This is the day. The swell is pumping at around 13 feet, with light, glassy winds off the ESE in the morning. The swell is from the SSE with a long 17 second period. The energy is strong, a reading of 9721. This is a big, powerful, clean swell for experts only. 13 feet is no joke, this is not the day for anyone but the most experienced. The afternoon adds a bit more size, hitting 16 feet with a light cross-onshore breeze. Morning is the go.
Wednesday the 26th and Thursday the 27th are more of the same, huge and unruly. We're talking 15 to 20 feet of swell with very strong energy. But the wind is up, a fresh 30-35 km/h cross-onshore, making it lumpy and chaotic. This is heavy, dangerous stuff for the elite only. It's going to be a survival session.
By Friday the 28th, the swell backs down to 7 to 10 feet, but the energy is still solid. The wind is lighter, but still on it. Still pretty messy, and the period has dropped to 9 seconds.
The 29th through the 30th gets smaller, with 5 to 7 feet of SSE swell. Winds stay light cross-onshore. It's surfable for the more experienced, but not great. The period is short, so it won't have much push.
Then we look ahead to the 31st. This is another morning with some real potential. The swell is a fun 5 feet, coming from the south with a 13-second period. The energy is solid. But the key is the wind, a light cross-offshore breeze from the WNW, which should keep the faces clean. This is a much more approachable window than the 25th and could be a nice, clean session for the experienced surfer.
September 1st also looks OK. Another 5 feet of south swell with a glassy morning and a decent 11-second period. It's promising, but there's a risk of thunderstorms, so keep an eye on the sky.
After that, it fades out again. The 2nd has some cleaner conditions in the afternoon with an offshore wind, but the swell is only around 3 feet. The 3rd and 4th see the swell drop below 2 feet, and even though the winds are offshore, there's just not enough juice. By the 4th, the wind is howling at 40-50 km/h, so you can forget about a clean surf. That's just blown out.
So, to wrap it up: If you're a charger, circle Tuesday the 25th. That's the standout. If that's too big, keep an eye on Monday the 31st for a much more manageable, clean session.
