The Lowdown

G’day, Rusty here again, looking at Narrabeen-Alley Rights.

Honestly, the first week and a half is a write-off. From the 14th right through to the 22nd, we’re looking at flat days and tiny, wind-affected slop. Energy readings are weak – mostly under 100 (71, 85, 103) – and we’ve got a run of cross-shore and onshore winds that will have it choppy and messy. The only glassy morning is the 18th, but there’s no swell to go with it.

Things finally start moving on the 23rd, when we see a jump in energy – 210 on the morning, with 1.7m of short-period ENE swell. But the period’s only 6 seconds, and wind is cross-shore, so it’s still marginal. The 24th and 25th see more size building, with the 25th morning bringing 1.8m from the NE and combined energy of 524. That’s the standout window – the wind goes cross-off from the NNE at 20 km/h, so it’s cleaner than anything else in the whole run.

The 26th morning has similar size at 1.8m from the NE (energy 678), but the wind is cross-shore and there’s a slight chop, so it’s not as good. After that, onshore southerlies and rain move in on the 28th, with 1.9m of windswell but poor quality. The 29th stays onshore with 1.3m to 1.4m of messy, wind-affected surf.

So the pick of the fortnight is the morning of the 25th. Narrabeen-Alley Rights is a beach and sandbar that’s very consistent, but it’s an advanced wave, so you need to know what you’re doing. That 1.8m from the NE is solid, and the light cross-off wind will keep it reasonably clean. Crowds are often, so expect some company. Water temp’s at 17°, which is about normal for this time of year.

If you can’t make the 25th, the 26th morning is the only other half-decent option, but it’s more of a gamble with the cross-shore chop. Everything else – forget it.

It’s a long wait, but there is a light at the end of the tunnel. Stay patient, and if that Friday morning delivers, it’ll be worth it.

Rusty out.

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.
