The Lowdown
Alright, pal, let’s talk about Narrabeen-Alley Rights. This is a beach and sandbar setup that’s exposed to the swell and only for the experienced crew. The water is sitting at 64°F, which is about normal for this time of year, so no worries about getting too cold.
The first week is a real grinder. From Tuesday September 1st right through to Monday the 7th, the swell is tiny – mostly 0.7ft to 1ft – and the energy is weak, with the combined energy of all swells directed here bouncing between 10 and 57. That’s barely a bump. The wind is often offshore or cross-off, so it’s clean, but there’s no power. You’d be sitting on a log hoping for a ripple. Not worth the walk.
On Tuesday the 8th, we see a little pulse. The morning has a 4ft swell from the NE with a period of 8 seconds, and the combined energy hits 143 – that’s moderate. The wind is cross-off from the WSW, so it’s clean. This is the first real chance for a wave, but it’s still not firing. The afternoon turns onshore, so the morning is your only window.
Wednesday the 9th and Thursday the 10th are back to flat, with energy down to 11 and 0. Don’t bother.
Here’s the one to circle. On Friday September 11th, the afternoon session brings a 4ft swell from the SSE with a 9-second period. The combined energy jumps to 290 – that’s moderate but with real grunt. The wind is cross from the NE at 15 mph, so it’ll be a bit bumpy, but it’s the best wave of the whole 16 days. The swell direction ENE is the sweet spot for this break. It’ll be busy because it’s often crowded, but for the advanced surfer, that’s your chance.
The weekend of the 12th and 13th is back to small – 2ft to 2ft from the SE, with low energy. The 12th afternoon goes glassy, which is beautiful, but the swell is too weak to get excited about.
The second week, from the 14th to the 16th, is mostly small and messy. The 14th afternoon has a 4ft swell from the ENE but the period is only 5 seconds and the wind is onshore, so it’s choppy and gutless. The 15th and 16th are similar – small, wind-affected, and not worth the paddle.
So the only standout is Friday September 11th afternoon. That’s your window. Everything else is a flat spell or a pass.
Rusty.
