The Lowdown

Alright, Rusty here. Let’s have a look at what’s lined up for us.

Honestly, the next couple of weeks are a bit of a mixed bag, with a lot of small, weak days to start with. There’s a real gap in anything worthwhile right off the bat.

We’re looking at Narrabeen-Alley Rights (a beach/sandbar setup) as the only spot with any recommendations. The first real chance to get wet without feeling like you’re just floating around is on Saturday, 30th August. It’s small, with waves around 2ft coming from the SSE, but the wind is glassy in the morning with a light NW breeze at 6 mph. That’s about as clean as it gets, so the surface will be like a mirror. The swell energy is pretty weak, only 117, so expect soft, small waves. It’s a good day for a beginner or for a longboard, but there’s not much push.

After that, we hit a massive dry spell. From Sunday, 31st August, right through to Tuesday, 8th September, the forecast is full of tiny or poor conditions. Most days have wave heights under 2ft, with some waves barely reaching 0.7ft. The wind is often clean or offshore, but there’s just no energy behind the swell. You’ll be paddling more than surfing. The best you’ll get in that stretch is Tuesday morning, 1st September, with 1.0ft waves and a clean offshore cross-off breeze, but the swell period is only 11 seconds, and the energy is just 39. It’s strictly a glimmer, not a session.

The only real standout in the whole window arrives on Wednesday, 9th September. This is the one to circle. The morning shows a proper SSE swell, pushing 8ft with moderate wave energy at 1186. That’s a solid, powerful lump of water. The wind is a cross-off breeze from the WSW at 15 mph, keeping things clean. This will be a big, grunty day at Narrabeen-Alley Rights. However, at 8ft, this is strictly for experienced surfers. Beginners should sit this one out. It’s a point break style wave here, and with the SSE swell, it should line up nicely. The crowds will be a factor though – this spot gets packed, and with a swell like that, expect it to be busy.

Friday, 11th September morning is worth a mention too. The swell drops back to a more manageable 5ft from the SSE, with a clean WNW cross-off breeze at 9 mph. The energy is still solid at 556, giving good shape. This is a far more user-friendly option than the Wednesday. The morning window is your best shot before the wind swings onshore in the afternoon.

The final days, around Saturday, 12th and Sunday, 13th, the swell fades back into the 3ft to 5ft range with lighter winds. Nothing to get excited about, just small, ordinary conditions.

To sum it up: the first week is a write-off. Get excited for Wednesday, 9th September if you’re an expert, and Friday, 11th September morning if you want a more doable, clean session. Everything else is just a paddle.

Stay safe out there.

Rusty.

A general guide to surfing at Narrabeen-Alley Rights can be found by selecting the local surf guide option on the grey menu.
