The Lowdown

G’day, Rusty here. Let’s cut to it—this stretch at Narrabeen-Alley Rights is mostly a waiting game. There’s a whole lot of flat, weak, and messy before we get one solid window, and then it dries up again. If you’ve got flexibility, circle Wednesday the 26th in the morning. That’s your shot.

The first few days are a bust. Saturday the 22nd and Sunday the 23rd have tiny waves around 1ft, with short, weak periods. It’s clean at times—Sunday morning is glassy—but there’s just no power behind it. Monday the 24th bumps slightly to 3ft–4ft but the period drops to 5 seconds, so it’s jumbled and mushy. Not worth suiting up.

Tuesday the 25th is a slight step up. The morning is surfable but ordinary with 3ft and a light cross-off breeze. The afternoon sees 4ft with a 9-second period and clean offshore wind, and the energy ticks up to 216 (moderate). It’s better, but still not the one.

Then Wednesday the 26th morning—that’s your standout. We’re looking at 6ft of northeast swell with an 8-second period, and the combined energy is a strong 648. The wind is light cross-off, so it should be clean and punchy. This is the best the window has to offer, no question. But don’t blink—by afternoon the south wind swings in at 25 km/h, turning it cross-on and choppy.

After that, it’s back to the grind. Thursday the 27th and Friday the 28th are poor, with onshore or cross-shore winds and weak swell. Friday morning is glassy with 4ft but not enough oomph. The weekend of the 29th and 30th is messy—light rain, onshore winds, and small waves. Monday the 31st stays poor.

Looking into early September, there’s a couple of mornings on the 1st and 4th with light offshores and surfable but very ordinary waves around 3ft–3ft. Not enough to get excited about. On the 2nd, the swell period stretches to 11 seconds but the wind blows hard onshore at 30 km/h, making it a lumpy mess. That afternoon jumps to 5ft but with a short period and cross-onshore chop—no good.

The final weekend of the 5th and 6th is a write-off—small, weak, and onshore.

So here’s the plan: aim for Wednesday the 26th morning. That’s the one with size, clean wind, and real energy. Everything else is just filler. Water temp is about normal for this time of year, so no surprises there.

Keep it on the radar, and I’ll see you in the water.

Rusty.

Information about the Narrabeen-Alley Rights Surf forecast

The above surf forecast table for Narrabeen-Alley Rights provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Narrabeen-Alley Rights can be found by selecting the local surf guide option on the grey menu. Our Narrabeen-Alley Rights surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Narrabeen-Alley Rights) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Narrabeen-Alley Rights may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
