The Lowdown
Alright, Rusty here. Let's talk about what's cookin' at Narrabeen-Alley Rights. It’s a bleak run ahead, I’ve gotta be straight with you. This is an exposed beach and sandbar setup. We’ve got a 16-day window, but there’s a big hole of nothing good to start with. You’re looking at a solid 12 days of pretty ordinary to poor conditions before anything remotely decent shows its face.
Right now, and for the next week and a half, it’s mostly tiny, weak surf with messed-up winds. The water temp is sitting around 63°F, which is pretty average for this time of year, nothing out of the ordinary.
Tuesday the 3rd of September is the only real standout in the whole run, and even then, it’s a half-day deal. On the Thursday morning, we finally get a pulse of energy with a combined energy of 239 (moderate), with 4ft swell coming from the SSE. That’s a short-period affair at only 7 seconds, but the kicker is a solid offshore from the NW at 12 mph. That will clean it right up and give you some proper, punchy walls for the experienced crew. It’s definitely an advanced-only kind of spot on a good day, and with 4ft, it’s not too big for them. The swell direction is also coming out of the SSE, which isn't the optimum ENE direction for the break, so the quality might be a little weird, but the offshore wind is a huge plus.
Before that, there’s nothing. The setup looks more interesting for a kite surfer than a paddle surfer for most of this period, given the onshore winds and small, weak surf. After that Thursday morning, it’s right back to small, weak, and ordinary.
So, if you can hold out, the morning of Thursday the 3rd of September is your only real shot at something half-decent. For the rest of it, you might be better off waxing your longboard for a flat day.
Rusty.
