The Lowdown
Okay, Rusty here. Let's take a look at the 16-day window for our stretch of coast.
Honestly, it's a bit of a slow grind to start. We've got a solid stretch of very small, weak surf that won't really get the heart pumping until we hit the second week. The best bet on offer looks like Tuesday the 8th of September, but we've got to work for it.
There's nothing doing for the first several days. From Thursday the 3rd through Monday the 7th, we're looking at tiny, weak waves—mostly around 0.7ft to 2ft from the ENE or NE, with almost no energy behind them. The swell energy is consistently in the teens or twenties (like 36, 27, 17), telling you there's just nothing on the table. The winds are often clean, especially on Saturday with a nice NW/NW offshore, but with waves that small, you're better off staying in bed or going for a paddle.
Now, here's where it gets a little interesting. Tuesday morning the 8th we see a pulse of 6ft from the SSE. The combined energy jumps to 426 - that's a moderate surge of energy and you'll feel it. This is the most powerful swell of the entire period. The problem? That wind is cross-onshore from the SSW at 12 mph, which will chop it up. It's not going to be pretty, but there will be waves if you're desperate and the paddle out won't be too punishing. It's getting too big for beginners, but for the crew who've been waiting this is the go. Later in the afternoon the wind eases but goes onshore, making it a real challenge to find a clean face.
After that, things get messy. Wednesday and Thursday the 9th and 10th bring more S/SSE swell around 6ft to 6ft, but it's all cross-onshore or onshore with a terrible short period of 6 to 7 seconds. At Narrabeen-Alley Rights, with this setup, it's more likely to be a bumpy, close-out mess that will look better for a kite surfer than a paddle surfer.
We then hit another quiet spell. From Friday the 11th through Monday the 14th we're back to tiny waves under 3ft, with the swell energy dropping back into the 50s and 60s. The only small consolation is Saturday morning the 12th, where we get 3ft from the NE with a light cross-offshore wind. The file says it's "surfable but very ordinary," and that's the truth.
Tuesday the 15th morning shows another flicker of life with a clean 3ft from the south, but the period is a terrible 5 seconds, and once the wind kicks in from the NE at 19 mph in the afternoon, it's game over.
The rest of the run stays small and forgettable. Wednesday the 16th through Friday the 18th is all sub-3ft waves, often with clean skies but no power to speak of.
So, to wrap it up: the real standout is Tuesday morning, September 8th. It's your best chance at a wave with some push (6ft from the SSE), but don't expect perfection with that cross-onshore wind. For a cleaner, although smaller, option, Saturday morning the 12th could offer a couple of playful ones on the bank if you're keen. Just be ready for a bit of a wait.
Stay patient, keep an eye on the forecast, and don't trust anything too far out.
Rusty.
