The Lowdown
Alright, Rusty here, let’s talk about what’s shaping up for our stretch of beach.
Right now, it’s a slow start. The beginning of the outlook is pretty quiet with only tiny chest-high waves, but I’ll walk you through the whole period as it lays out.
Narrabeen-Alley Rights is the only spot in the game, and it’s a very consistent, exposed beach/sandbar setup that needs an easterly push. The water temperature is sitting at 64°, which is bang on average for this time of year, so nothing out of the ordinary there.
The first few days have surfable waves but they are very ordinary. On Tuesday 1st September, we’ve got clean 1ft waves from the ENE with a 11-second period, light offshore breeze, and combined energy of just 57. It’s tiny but clean. Wednesday morning keeps the same 1ft, 10-second period pulse with a moderate NW offshore, but the energy is only 60. Thursday through to Sunday the 6th dawns are all poor conditions, with barely any swell.
The first real standout comes on Monday 7th September morning. It’s glassy with a 0.7ft E swell, period 10 seconds, but it’s almost flat. The next morning, Tuesday 8th September, we see a proper bump: 3ft from the SSE with a 9-second period, light cross-offshore breeze, and combined energy jumps to 323. That’s moderate wave energy and the conditions look clean. The afternoon holds 3ft at 242 energy, still clean but with a bit more breeze. This is the best on offer in the first week.
Then we hit a dry spell. From Wednesday 9th September afternoon through to Friday 11th September, it goes flat – zero energy. Saturday 12th and Sunday 13th are poor, with messy cross-shore winds and only 0.7ft to 3ft of lumpy swell.
The second standout comes on Monday 14th September morning. The swell builds to 4ft from the ESE with an 11-second period, combined energy of 410 – that’s solid moderate wave energy. The wind is a light cross-offshore, so it’ll be clean. This is the best of the whole outlook. 4ft ESE with cross-offshore breeze, clean lines, and decent energy. After that, Tuesday 15th drops back to 2ft and weak energy, then it fades out to poor conditions through the rest of the period.
So, if you’re picking your moment: Tuesday 8th September for a clean, punchy SSE swell, and Monday 14th September is the real standout – 4ft ESE, clean, with the most energy of the run. The long gap between the 8th and the 14th is a bummer, but that Monday morning makes up for it.
Remember, this is a very consistent spot, so it’ll fire again soon. The crowds are often here, so you’ll have company on the good days.
Rusty.
