The Lowdown

Alright folks, Rusty here. Let’s see what’s cooking at Narrabeen-Alley Rights over the next couple of weeks.

Right off the bat, the first week is a total bust. We get a couple of surfable sessions on Monday the 10th – a morning pulse of 7 ft from the ENE at 9 seconds, but it’s a tough ask. The wind is screaming offshore at 22 mph, which keeps it clean, but paddling into anything is a real grunt. The combined energy is moderate at 659. By the afternoon, the wind is even stronger, and the swell drops to 6 ft. It’s just not worth it. After that, the rest of the week is flat or tiny, with onshore winds and rain showers.

We’re looking at about a ten-day dry spell, until Thursday the 20th. That morning things start to shift. The wind goes light from the WNW at 3 mph, and it’s glassy. The swell is tiny, only 3 ft from the SE at 7 seconds, but it’s clean. The energy is weak (102). It’s a little tease.

Now, here’s the one to get excited about. Friday the 21st of August. The morning is pure magic. Dead calm, flat glass, and a solid 6 ft swell from the ENE at 8 seconds. The combined energy jumps to strong at 737. This is the best on offer – clean, punchy, and the direction is perfect for this spot. It’s a bit much for beginners, but for the experienced crew, it’s going to be a classic. Crowds are often around, so get there early.

The weekend keeps the goods coming. Saturday the 22nd morning stays glassy with light NNW winds and a 5 ft ENE swell. The energy is moderate (404), and it’s clean. Then Sunday the 23rd morning brings a bigger pulse: 6 ft from the E, with a longer period of 11 seconds and a very strong energy reading of 1119. The wind is cross-off from the NNE at 12 mph, so it’s clean. The longer period means better shaped waves with more power, but it might straighten out a bit on the beach. For a point break, it’s a beauty.

Monday the 24th morning holds up with a 6 ft E swell, light cross-off winds, and a clean surface. The energy is moderate (585). Tuesday the 25th fades to 4 ft from the E with some rain, but still clean.

The water temp is about average for this time of year, nothing wild.

So, bottom line: skip the first ten days, but lock in Friday the 21st through Sunday the 23rd. That’s the window. The long-range stuff looks promising, but it’s not set in stone yet.

Rusty.

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.

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.
