The Lowdown
Alright, let’s talk about what’s showing up. The ocean’s got some life in it, but the wind’s gonna be the boss of this show. The water’s at 82°F, which is right where it should be for this time of year, so no weirdness there.
The first real chance to paddle out is Saturday morning, September 5th. Akabane Long Beach will have a clean 3ft swell out of the SSW with a 10-second period and a light offshore breeze. The combined energy is moderate at 216. It’s not going to blow your mind, but it’s clean and rideable. That morning window is your only window for the day. The afternoon turns into a mess with onshore wind and chop.
Sunday the 6th is a total washout. We’re looking at a massive 10ft to 12ft cross-shore swell with near gale-force winds. The energy is huge (1143 to 2086), but it’s pure chaos. This is a day for the kite surfers, not the paddle crew. Leave the boards at home.
Now, here’s the one to circle. Monday morning, the 7th of September. The wind goes offshore from the NW, light at 9 mph, and the swell is a solid 8ft from the SSE with a 10-second period. The combined energy is a strong 1735. This is proper groundswell, full of power. It’s going to be big and clean, but at this size, it’s strictly for the experienced crew. The long period means the waves will have plenty of push, but at a beach break like this, it might close out and be a bit walls. Still, if you’ve got the chops, this is your session. The morning is excellent, and the afternoon holds similar size at 10ft (1692 energy) with the same offshore wind, though the forecast notes it might be too big for this spot. Either way, Monday is the highlight.
Tuesday the 8th is still very good. The swell drops a bit to 7ft from the SSE, and the morning has a light cross-offshore breeze. The afternoon turns glassy, dead calm, which is a rare gem. The combined energy is 924 to 1160. It’s still a solid, clean groundswell for experienced surfers.
Wednesday the 9th morning has another clean offshore window, with an 8ft SSE swell (1353 energy). The afternoon breeze picks up but stays clean. It’s still good, but not as crisp as the morning.
After that, it’s a downhill slide. Thursday the 10th sees the swell drop and the wind go cross-shore, creating chop. Friday the 11th is a loss with strong onshore winds. Saturday the 12th and Sunday the 13th have a tiny 2ft to 3ft swell with a very long 14-second period, but the conditions are poor. The energy is weak (around 193 to 270). It’s barely worth a look.
The second week is a real struggle. From Monday the 14th through to the end of the 16-day run, the swell stays small, mostly under 4ft, and the wind is almost always onshore or cross-shore. There’s a brief moment on Wednesday morning the 16th with glassy conditions on a 4ft swell, but it’s short-period (6 seconds) and weak in energy (162). Hardly worth the paddle. The final days, from the 18th to the 20th of September, are tiny, with weak, short-period swells and either glassy or offshore winds, but the waves are just too small to get excited about.
So, to wrap it up: Monday the 7th of September morning is the one to chase. Tuesday morning is a solid backup. After that, the window closes. Keep your eyes peeled – forecasts can shift.
