The Lowdown
Alright, Rusty here. Let's have a look at what we've got coming down the line for Narrabeen-Alley Rights. It's a beach and sandbar setup, exposed to the swell, and with a bit of size it can handle it, but it needs the stars to align.
Right now, the immediate outlook is pretty grim. The first few days are flat and messy. We're looking at small, weak, onshore choppy junk through Wednesday the 26th and Thursday the 27th. Not worth paddling out for. The water temp is about average for this time of year at 63°F, so nothing to worry about there.
Friday the 28th morning is the clear standout. This is the one to get excited about. We've got a solid 5ft swell rolling in from the SSE, with a period of 11 seconds. That's a proper groundswell, and the combined energy is a solid moderate 679. The wind is WSW at 6 mph, giving us a light cross-offshore breeze. For a beach break, that's about as clean as you can ask for. It might have a bit of a long period feel, so keep your eyes open for sets, but the quality will be there. This is your window. Be ready for a crowd though, it can get busy here.
After that, it drops off again. Saturday the 29th and Sunday the 30th have small waves with iffy conditions. Monday the 31st is glassy but tiny. Through the first week of September, it's a long, flat spell. There's a massive gap here with nothing really doing. We get a little pulse of 6ft on Tuesday the 8th of September, but it's a short-period, weak windswell with a combined energy of 309. The wind is offshore, but the quality is marginal at best.
For the rest of the second week, it's mostly small and onshore, with a nasty southerly gale forecast for the 9th and 10th of September. That's just a write-off. So, to be blunt, save your energy for Friday the 28th morning. That's the only proper call in the whole window.
Stay stoked,
Rusty.
