The Lowdown

Alright folks, Rusty here. Let's have a look at what’s cookin' for Narrabeen-Alley Rights over the next couple of weeks.

To be straight up, this is not a good run. The whole 16-day window is a bit of a heartbreaker for a spot that can be a gem. There’s practically nothing for the first week and a half. We’ve got a stretch from the 16th right through to the 25th of September where the surf is poor. The first half of that week is flat out tiny or wind-bent, and even when there’s a touch of size, the conditions are just ordinary.

Now, the only window that looks worth paddling out for is right at the back end. The standout moment is Sunday afternoon the 27th of September. We’ve got a clean 6ft swell out of the NE, and the wind going light offshore or cross-off from the WNW. The wave energy is picking up to a solid 271 (moderate) and the wind is going clean. For an advanced break like this, that’s the pick of the fortnight, but it’s a long way off, so don’t lock it in just yet.

Monday the 28th of September morning also looks promising. A clean, gentle offshore from the NNW with a solid 5ft swell out of the ENE and energy climbing to 230 (moderate). That could offer some proper lines.

Forget the rest. From the 29th, it’s back to choppy, cross-onshore slop. This break only really shines for the experienced crew, and even then, there’s nothing for beginners in this window. If that Sunday the 27th shapes up, be on it.

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.
