The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Narrabeen-Alley Rights. Bit of a tough stretch ahead, but there’s a light at the end of the tunnel.
We’re starting off with a pretty bleak run. From Friday the 28th of August right through until Thursday the 10th of September, the surf is just not playing ball. There’s a ten-day gap here where you’d be hard-pressed to find anything worth paddling out for. The energy in the water is weak to moderate at best, with the combined swell energy sitting around the 100–200 mark (462), dropping to barely a ripple. Winds are mostly onshore or cross-off, with the odd glassy moment on Sunday the 30th morning – but the swell is tiny at 2ft from the SSE. It’s surfable but very ordinary.
The water temp is sitting at 64°, which is about normal for this time of year – nothing to write home about.
Now, the one true standout in this entire 16-day window is Saturday the 12th of September. That morning, we’re looking at a solid 7ft SSE groundswell with a period of 10 seconds. The combined energy jumps right up to 919, which is strong. But here’s the kicker – the wind is light from the NNE, swinging offshore, and it’s clean. This is a serious contender. It’s a bit on the bigger side, over 7ft, so this one’s for the advanced crew. The best of the best is Narrabeen-Alley Rights itself, with that 7ft swell pushing in from the SSE, light offshore breeze, and the vibe should be good. Crowds can be an issue here – it’s often busy – so get in early. The swell is a bit long in the tooth at 10 seconds, but still plenty of juice for a proper right-hander.
The afternoon of the 12th sees a bit of a drop-off, with a cross-shore wind and the swell dropping to 6ft and a chop building. Not the same quality.
After that, it’s back to small, weak conditions through the rest of the forecast, with the odd pulse but nothing that’ll get your heart racing this far out.
Signing off, Rusty.
