The Lowdown

Alright, Rusty here. Let's have a look at what we've got coming down the line for Narrabeen-Alley Rights. It's a beach and sandbar setup, exposed to the swell, and with a bit of size it can handle it, but it needs the stars to align.

Right now, the immediate outlook is pretty grim. The first few days are flat and messy. We're looking at small, weak, onshore choppy junk through Wednesday the 26th and Thursday the 27th. Not worth paddling out for. The water temp is about average for this time of year at 63°F, so nothing to worry about there.

Friday the 28th morning is the clear standout. This is the one to get excited about. We've got a solid 5ft swell rolling in from the SSE, with a period of 11 seconds. That's a proper groundswell, and the combined energy is a solid moderate 679. The wind is WSW at 6 mph, giving us a light cross-offshore breeze. For a beach break, that's about as clean as you can ask for. It might have a bit of a long period feel, so keep your eyes open for sets, but the quality will be there. This is your window. Be ready for a crowd though, it can get busy here.

After that, it drops off again. Saturday the 29th and Sunday the 30th have small waves with iffy conditions. Monday the 31st is glassy but tiny. Through the first week of September, it's a long, flat spell. There's a massive gap here with nothing really doing. We get a little pulse of 6ft on Tuesday the 8th of September, but it's a short-period, weak windswell with a combined energy of 309. The wind is offshore, but the quality is marginal at best.

For the rest of the second week, it's mostly small and onshore, with a nasty southerly gale forecast for the 9th and 10th of September. That's just a write-off. So, to be blunt, save your energy for Friday the 28th morning. That's the only proper call in the whole window.

Stay stoked,
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.
