The Lowdown

Alright, mate, Rusty here. Let's have a good look at what's on the cards for the next couple of weeks.

We're looking at a pretty mixed bag, with a big gap of pretty ordinary conditions before we get a couple of standout windows. The first decent surf we see is a bit of a tease, but the real quality is a way off, so keep your patience.

The Rundown

To start things off, we’ve got a tiny pulse on Monday the 7th. First thing in the morning at Narrabeen-Alley Rights, there's a clean 2 ft swell from the SSE with a light NW offshore. The water temp is about average for this time of year at 65°, nothing wild. The combined energy is weak (65), so it's more of a paddle than a proper session. That's gone by the afternoon when the wind swings onshore.

After that, we are in for a real dry spell. From Monday afternoon right through to the morning of Saturday the 12th, it’s mostly poor surf with strong, messy winds and tiny, gutless waves. Honestly, it's not worth getting the wetsuit wet. There's a few days there where the swell is so small and the wind is so bad, you're better off doing something else.

Then, finally, on the morning of Saturday the 12th, we get a proper window. The stars align for a bit. Narrabeen-Alley Rights wakes up with a glassy 5 ft SSE groundswell. The period is a solid 11 seconds, which means proper lines and long waits between sets. The wind is dead calm, glassy as anything. The combined energy is strong (664), so there's plenty of push. This is the standout of the entire outlook. It’s advanced-level territory with that size, so the crew out there will be in for a treat. It's a very consistent spot, so expect it to be busy, but it will be worth competing for a wave.

The window doesn't last long. The afternoon on Saturday gets a bit lumpy, and Sunday the 13th is a step down with smaller, weaker surf.

We then hit another patch of average to poor conditions for several days, with a lot of onshore and cross-shore wind.

The next real highlight is a long way off, and the models are still a bit shaky this far out, but it's worth keeping an eye on. The morning of Thursday the 17th of September looks promising. We've got a solid 8 ft SSE swell pushing in with a combined energy of 1011, which is very strong. The wind is light and cross-onshore, so it might be a bit bumpy, but that's a lot of water moving. That's expert-only territory—super heavy and not for the faint-hearted.

Following that, the morning of Friday the 18th of September also looks good with a clean 5 ft SSE swell and a moderate NW offshore wind. The energy is still solid (333), and the conditions look clean. That's a good, solid session for the advanced crew.

After that, it trails off again into smaller, weaker stuff with average winds for the rest of the outlook.

So, to sum it up: the best of the best is the glassy morning of Saturday the 12th. If you can't make that, the big swell on Thursday the 17th is for the hardcore, and the clean morning on Friday the 18th is a solid backup. Don't bother with the rest.

Stay salty.
