The Lowdown
Alright folks, Rusty here with a look at what's coming up for Akabane Long Beach.
First off, the water temp is sitting right around 81°F, which is pretty much what you'd expect for this time of year – nothing unusual there.
Right now, there's nothing to get excited about. We've got a run of small, weak, and messy conditions that'll keep the boards in the car. Wednesday afternoon the 19th through to Sunday the 23rd is all tiny, weak swell with poor winds, so don't even bother.
Monday the 24th is where things start to get interesting. The morning session is the real standout here. We've got a clean 4ft swell rolling in from the SSE with a solid 15-second period. That's a proper groundswell, and with glassy conditions and light winds, it's going to be clean and lined up. The wave energy is moderate (688), so there's some punch. This is the best call of the whole 16-day window.
Later that Monday afternoon the wind swings onshore and chops it up, so get out early.
The next morning, Tuesday the 25th, sees a bigger 7ft SSE swell with a 14-second period, but it's still holding some shape. That's getting into the intermediate zone but still manageable for the experienced. The afternoon bumps it up to 8ft with a 16-second period, but the wind is onshore.
From Wednesday the 26th through to the end of the month, the swell gets big – really big. We're talking 12ft to 13ft SSE swells with very long periods. The wave energy is through the roof (6000+). This is expert-only territory, and the winds are mostly cross-on or choppy, so it's messy. The setup looks more interesting for kite surfing than paddle surfing during this period.
Then, on the 31st of August, Monday morning, we get another window. The swell has dropped to 8ft from the SE, with a moderate 11-second period, but the wind is glassy and light. That's excellent for experienced surfers.
Finally, September 2nd, Wednesday morning, brings a 8ft SSE swell with a cross-off wind, making for clean conditions. Another good one for the experienced crew.
So, to wrap it up: the absolute best on offer is Monday morning the 24th of August. Get out there for the clean, glassy, 4ft SSE groundswell. The second standout is the 31st of August morning for the 8ft glassy conditions, and then September 2nd morning for the clean cross-off. Everything else is either too small, too messy, or too big.
Stay safe out there.
