The Lowdown
G’day, Rusty here. Let’s chat about what’s shaping up at Narrabeen-Alley Rights.
Truth be told, it’s a quiet stretch. For the first week there’s hardly anything that’ll get you out of bed—mostly tiny waves, onshore slop, or barely a ripple. The real standout is a short window, and it’s a little way out.
Your main event, and really the only proper call across the 16 days, lands on the morning of Friday, 28 August. Narrabeen-Alley Rights will be pumping with a clean 6ft SSE swell at 11-second intervals, pushing moderate energy into the bank (669). The wind is glass from the WNW at just 3 mph. That’ll set the beach/sandbar up perfectly—smooth, lined-up, and with enough grunt to get the adrenaline going. This one’s for the advanced crew; expect a crowd (it’s “often” busy), but it’s well worth it.
After that, the dry spell really kicks in. Saturday morning (29 August) offers 4ft with a cross-shore breeze—rideable but nothing special. From Sunday all the way through to early September, it’s mostly tiny, messy, and weak. There’s a solid gap from Sunday 30 August right up to Tuesday 8 September where hardly any surf is worth a look.
There’s a glimmer on the morning of Tuesday, 8 September with a 3ft SSE groundswell at a very long 15-second period and glassy conditions. The energy is moderate (304), and the waves will have nice shape, but it’s small—better for a longboard. That same afternoon jumps up to 8ft from the SSE (strong energy at 1257), but the wind swings cross-shore at 16 mph, making it a bumpy, messy option only for the brave. After that, it’s back to tiny, weak dribble for the rest of the run.
So to sum it up: if you want clean waves, you’ve got one sharp window—the morning of 28 August. Everything else is either too small, too windy, or just not worth the hassle. Water’s sitting around 64°F—barely a tick below average for the time of year, no big deal.
Keep the stick waxed and wait for that Friday morning.
Rusty.
