The Lowdown
G’day, Rusty here. Look, I’ve had a good look at the charts for Narrabeen-Alley Rights, and if I’m being straight with you, the next 16 days are a mixed bag with a long, frustrating flat spell in the middle. There’s a couple of windows of hope, but you’ll need to pick your moments.
The first real go is Monday, 3 August. The morning brings a 3ft SE swell, period 11 seconds, with a combined energy of 236 – that’s moderate energy, but it’s got some shape. The wind is cross-off from the north at 9 mph, so the lines should be clean. It’s a beach/sandbar, so a long period groundswell like this can be a bit straight at times, but the ENE optimum swell direction matches well enough. This is the standout of the whole period. The water temp is 63°, which is about 1° cooler than normal, so nothing crazy, just a touch of winter bite. For the advanced crew, this is the one.
The afternoon fades a bit – 3ft from the SE, still 11 seconds, but the cloud rolls in and the energy drops to 194. It’s surfable, but ordinary. Tuesday morning, 4 August, the swell drops to 1ft SE, period 10 seconds, energy down to 54. That’s weak. The wind is light from the west, so it’s clean, but there’s just not enough push. By Tuesday afternoon, it’s glassy but only 0.7ft – poor conditions.
Then we hit a dry spell. From Wednesday, 5 August, through to Friday, 8 August, the swell is tiny, mostly 1.0ft to 1ft, with periods as low as 5 seconds. The energy is under 60 – weak. It’s a write-off. Saturday, 8 August, is glassy in the morning but only 1ft, and the afternoon brings a cross-shore chop. Nothing doing.
Sunday, 9 August, sees a pulse of 4ft NE swell, but the period is a short 6 seconds, so it’s weak and messy. The combined energy hits 152, but the wind is 12 mph from the north in the morning, shifting to 16 mph offshore in the afternoon. It’s clean, but the short period makes it junky. Not worth a paddle.
From Monday, 10 August, the swell hangs around 2ft to 3ft ENE, but the wind is often strong – 19 mph on Monday morning – and the energy stays low. There’s a blip on Wednesday, 12 August, with a 4ft NE swell at 4 seconds – that’s a joke of a period, energy only 68. Poor. Thursday, 13 August, the energy jumps to 250 from a 3ft NE swell, but the wind is onshore or cross, and it’s poor.
The rest of the second week fades again. Saturday, 15 August, through to Tuesday, 18 August, is mostly 1.0ft to 2ft, with some glassy moments on the 18th, but the energy is weak. The exception is Monday, 17 August, with a 2ft SSE swell and 103 energy, but it’s cross-shore and ordinary.
Overall, the best of the lot is Monday, 3 August, morning. That’s the only time the stars align a little. The rest is a long gap of flat or poor surf. It’s not the best time for Narrabeen, but if you’re keen, hit that Monday morning window.
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.

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.
