The Lowdown
G’day, Rusty here. Let’s be straight up – it’s a pretty bleak run for the next week and a bit at Narrabeen-Alley Rights. We’ve got a right-hander that likes ENE swell, but most of the forecast is junk: tiny swell, onshore winds, and weak energy. Don’t get excited, but there’s a light at the end of the tunnel if you’re patient.
Starting out, this Saturday morning (29 August) you’re looking at a weak 4ft SSE swell with a cross-on SSW breeze at 6 mph – total energy is a measly 341, and it’s just marginal. Saturday afternoon stays small and onshore. Sunday morning (30 August) drops to a tiny 2ft from the SE but turns glassy with a light NW wind – still, the energy’s only 123, so it’s flat and ordinary. Then from Sunday afternoon all the way through to almost the second week of September, it’s a desert: days of 0.3ft to 2ft junk, poor conditions, and scores of zero. There’s a gap of about nine days where there’s nothing worth paddling out for.
Now, come Thursday morning 10 September – that’s your standout. Overnight, the swell jumps to 7ft from the SSE with a 12-second period and a combined energy of 1140 – that’s strong. It’s glassy, offshore from the SW at just 3 mph, and the water temp is 64°, which is about average for the time of year. This is only for experienced surfers though – 7ft is pushing expert territory, and at a beach/sandbar setup like this, that SSE swell might be a bit straight, but with glassy conditions, the rights will have power and shape. Thursday afternoon gets a cross-on breeze and drops to 6ft, so grab the morning.
Friday morning 11 September still has a fun 4ft SSE swell, glassy with a light W wind, and energy down to 489 – moderate but clean. That’s worth a look if you missed Thursday. After that, it fades back to tiny stuff and onshore winds for the rest of the outlook.
So, to be clear: the only real call is Thursday 10 September morning. Big, clean, expert-only waves. Everything else is a scratch. Rusty.
