The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming down the line.

Honestly, this stretch is a bit of a tough one. There’s swell around for sure, but the quality is just not there for most of it. We’re looking at two weeks of small, weak, and often messy conditions at Narrabeen-Alley Rights. There are a few windows where it cleans up, but nothing really gets that combination of size and good wind to fire. The first week is the main focus, but even that is patchy.

Friday, August 21st – The best bet of the whole run, and that’s not saying a lot. A small 3 ft swell from the ENE, with an offshore NW wind at 9 mph. It’s clean, but the energy is weak (62). This is the one morning worth paddling out for a few grovelly ones before it all goes flat again.

Saturday, August 22nd through to Wednesday, August 26th – A real flat spell. Swell drops to 1 ft to 2 ft over the weekend, with nothing worth mentioning. Monday and Tuesday see a tiny bump to 3 ft and 4 ft, but the wind is all over the shop – cross-off at best, with a messy 19 mph cross-shore on Monday afternoon. The combined energy is moderate (110–126), but the wave comment says it all: just ordinary. By Wednesday the swell builds a little to 4 ft, but it’s cross-shore rubbish.

Thursday, August 27th – A short-lived glimmer. 3 ft from the ENE, with glassy conditions thanks to a WSW wind at just 3 mph. It’s clean, but the energy is moderate (134) and the direction is just okay for this break. You’ll get some little ones if you’re keen.

Friday, August 28th through to Tuesday, September 1st – Another flat, messy run. Swell sits around 2 ft to 3 ft, with only Friday morning offering a clean 2 ft from the NE under a light offshore. The rest is cross-onshore crud, with wind getting rowdy on the 30th (22-25 mph). A kite would have a better time than a paddle board during that.

Wednesday, September 2nd - A brief quiet morning – 2 ft from the E, period stretching to 11 seconds, and clean with light NNE wind. It’s weak, though (energy only 72). Small and clean for a longboard, but nothing exciting.

Thursday, September 3rd – The last day of interest. Morning has 2 ft from the E at 10 seconds, clean with light N wind. Then the afternoon bumps up to 5 ft from the NE – the biggest swell of the run – but it’s a short-period 5 second mush burger with a 12 mph wind. It’s blown out and ugly.

Friday, September 4th and Saturday, September 5th – A bit of a hopeful note for the distance. Friday morning has 3 ft from the NE, offshore NNW wind, clean. And Saturday is interesting: a long-period 15 second groundswell from the SSE at 2 ft, with light offshore wind. The energy is moderate to strong (135–164). But that’s a long period for a beach break; it’ll be fickle and likely too straight. Still, a clean, long-period day in early spring is something to put on the radar, even if it’s a long way off.

So, to wrap it up: the standout is Friday, August 21st morning. Small, clean, and the only session that feels worthwhile. Saturday, September 5th is a wildcard for the longboard crew, but it’s too far out to rely on. The rest is a whole lot of flat, messy, or just plain ordinary. It’s not looking great, but that’s the coast for you – it’ll turn around.

Rusty.
