The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

First up, we’re looking at Narrabeen-Alley Rights (a beach/sandbar setup). This stretch is exposed and likes swell from the ENE. Water temps are sitting at 17°, which is about 0.7° cooler than average for this time of year – nothing too wild, just a touch on the nippy side.

The 16-day period starts off pretty average, to be honest. The first solid call comes on the morning of Monday the 24th of August. We’ve got a small NE swell at 3 ft, only 5 seconds period, so it’s short-period windswill. The combined energy is weak at 53, and with a light N breeze creating a cross-off, the conditions are clean but the waves are very ordinary. You won’t be missing much if you give it a miss.

Tuesday the 25th of August sees a bit of a jump. The morning swell pushes to 5 ft from the NE with a 7-second period and combined energy at 326 (moderate energy). The wind is a moderate N cross-off, so the surface looks clean. The afternoon is actually the better window: 5 ft from the NE, 8-second period, with a NNW cross-off at 9 mph. The energy drops a little to 229, but the conditions are expected to be good. This is the standout window across the whole period – it’s not huge, but the wind is tidy and you’ll get some fun, clean lines.

Wednesday the 26th of August turns ugly. A risk of thunderstorms in the morning with S winds, and by the afternoon, it’s onshore and choppy with 6 ft from the south. That’s too lumpy and messy for a decent paddle – honestly, the wind and chop make it look more like a kite day than a surf session.

From Thursday the 27th through to the end of the month, the surf drops right off. We’re looking at small swell – 2 ft or less – with periods ranging 8–11 seconds. Combined energy barely gets above 100. There is a brief moment on Friday morning the 28th of August when the wind goes glassy (NNW, 3 mph) and the swell is 2 ft from the ENE, 8 seconds, but the energy is only 61, so it’s tiny and ordinary. You’ll get a few tiny glassy rollers but nothing to write home about.

The first week of September is dead: from the 1st to the 6th, we’ve got swell heights of 2 ft or less, mostly ENE, with periods up to 10 seconds. The combined energy is in the teens to low 60s. There are a few clean mornings with light offshore or glassy conditions (like September 1st morning, WNW 3 mph, clean), but the waves are tiny. You’d be scratching for anything rideable.

Finally, on the 7th and 8th of September (Monday and Tuesday), things perk up a little. The 8th (Tuesday) morning has a 4 ft NE swell with 7-second period and energy at 140. With a W cross-off at 9 mph, it’ll be clean and surfable. Still nothing special, but you can get a few. It’s a long way out, so treat that with a grain of salt.

The best on offer? Tuesday afternoon the 25th of August. Swell 5 ft from the NE, clean cross-off wind, and the energy is in the moderate zone. That’s your window. Everything else is either too small, too messy, or both.

Stay salty.

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.

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.
