The Lowdown
Righto, it's Rusty here, and I'm looking straight at what's on offer for Narrabeen-Alley Rights. And mate, I gotta be straight with you – it's a pretty quiet stretch ahead. This is a beach/sandbar setup that's exposed to ENE swell, but the models are showing a whole lot of nothing for most of the next two weeks.
We kick off on Thursday the 3rd with tiny 1 ft ENE swell, and a 12 mph W cross-off breeze. The combined swell energy is a weak 36, so there's just no push. Friday the 4th morning sees the wind drop to glassy, but we're still stuck with that same pathetic 1 ft. The water temp is sitting at 64°, which is about average for this time of year, so at least you won't freeze while you're sitting there waiting for a wave that never comes.
The whole first week is a write-off. We've got a solid run of 'poor surf conditions' with tiny swell and mostly average winds. Saturday the 5th afternoon brings a slight bump to 3 ft from the NE, but the period is a short 6 seconds, so it's just wind chop. The combined energy is a weak 43.
Now, there is one moment that stands out, but it's a tricky one. On Thursday the 10th of September, we see a solid jump. The morning has a 7 ft SSE swell with a combined energy of 587, and the afternoon pushes up to 8 ft from the SSE with a period of 14 seconds and a combined energy of 2789 – that's a powerful, long-period groundswell. This is definitely one for experts only, as 8 ft is big and punchy. The wind, however, is a cross-onshore from the SSE at 12 mph, so it's going to be choppy and messy. For a beach break like this, that long period can make it break a bit straight and closey, especially with that cross-onshore wind. Honestly, with that much swell and poor conditions, this setup might actually be more interesting for a kite surfer than a paddle surfer. It's a marginal call at best.
After that, we're back to tiny dribble. Friday the 11th morning has clean conditions with a 0.7 ft E swell from a WSW cross-off at 3 mph, but again, no power. The rest of the outlook into the second week is more of the same – small, weak swells with periods all over the shop, but nothing that's going to get your heart racing. We see a clean morning on the 18th with a 1 ft NE swell and an offshore WNW breeze at 6 mph, but it's just not enough to work with.
So, the honest truth? There are no real standouts here. The only flicker of size on the 10th is ruined by the wind and the beach break nature. You're looking at a long, dry spell. It's a tough one, but that's how it goes sometimes.
Stay patient,
Rusty.
