The Lowdown
Alright mate, Rusty here. Let’s have a look at what’s coming down the line for Narrabeen-Alley Rights.
Honestly, this is a tough run. We’ve got a 16-day window, but for the first 11 days there’s hardly a wave worth paddling out for. The swell is tiny, the wind is messy, and the energy readings are mostly in the single or low double digits. It’s a real flat spell to start.
Tuesday the 8th sees a bit of a pulse in the afternoon with a 7 ft swell from the SSE, and the combined energy jumps to 546 – that’s moderate wave energy right there. But the wind is onshore from the SE at 6 mph, and the conditions are labelled as marginal. It’s probably worth a look if you’re desperate, but don’t expect much.
Thursday the 10th and Friday the 11th are basically write-offs. We’re talking 0.7 ft to 0.3 ft swells with onshore winds. The water temperature is about average for September.
We finally get a bit of hope on Saturday the 12th. Morning is clean with a light NNW cross-offshore breeze at 6 mph. The swell is a tiny 0.7 ft from the ENE with a long 14-second period, but the wave energy is only 19 – weak stuff. It’s glassy, but there’s just no power. That afternoon gets chopped up again.
The pattern continues for the next week: small swells, variable winds. On Wednesday the 18th, the morning goes glassy with a NW wind at 3 mph, but the swell is only 0.7 ft. In the afternoon, there’s a bump to 3 ft from the SSE with a 10-second period and 211 moderate wave energy, but the cross-shore wind from the NE at 12 mph makes it messy.
Now, the standout in this whole outlook is Saturday the 19th. The morning brings a 2 ft SSE swell at 9 seconds, combined energy of 184 – moderate – and a moderate offshore wind from the NW at 12 mph. That’s clean. For Narrabeen-Alley Rights, this is the best of a quiet bunch. It’s a beach setup though, so don’t expect perfection. It’s surfable and clean, which is a win in this forecast. Remember, these long-range calls for the second week are promising but less certain.
After that, it’s back to small and clean on Monday the 21st with a glassy morning, and then small, clean conditions right through to Wednesday the 23rd, but still no significant swell to write home about.
There’s really only one window that looks worth a paddle – the morning of Saturday the 19th. For the rest, you’re better off checking the forecast in a few days.
Rusty.

Information about the Narrabeen-Alley Rights Surf forecast

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

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.
