The Lowdown

G’day, it’s Rusty. Lookin’ at Narrabeen-Alley Rights for the next couple of weeks, it’s a tough stretch. This is a beach and sandbar spot that’s exposed to swell, but the conditions are just not fallin’ into place for a proper paddle.

Right off the bat on Wednesday, September 2nd, we’ve got a tiny 1ft swell out of the ENE with a 10-second period. The wind is a cross-off at 15 km/h, so it’s clean, but the energy is weak (48). The water temp is 64°, pretty average for the season.

Thursday the 3rd sees the wind pick up to 25 km/h from the WNW, but the swell is still only 2ft with a real short 5-second period – no power there. Friday the 4th morning goes glassy with calm air, but the swell’s down to 1ft. The afternoon gets onshore and choppy.

This pattern of small surf and average winds hangs in until Tuesday the 8th. On the morning of the 8th, a pulse of 6ft swell shows up from the SSE with a short 8-second period and moderate wave energy (412). But the wind’s onshore at 15 km/h – messy.

On Wednesday the 9th afternoon, another pulse of 6ft SSE swell hits with 30 km/h cross-on winds. Fresh breeze, strong energy at 219, but it’s blown-out. This is a kite surfer’s day, not a paddle surfer’s.

The one real glimmer comes on Saturday the 12th. The morning has a 4ft swell from the SSE with an 11-second period – that’s a groundswell with some travelling power – and the energy is moderate-strong at 447. The wind is cross-off from the NNE at 15 km/h, so it’s clean. This is your standout of the fortnight. The break is *very consistent*, and on a day like this, you can expect crowds often. The swell direction (SSE) isn’t the absolute best for the spot (optimum is ENE), so the lines might not be perfect, but it’s your best bet.

Sunday the 13th morning is glassy with a 3ft NE swell but a weak period (6 seconds), so it’s just ordinary. The rest of the week into the 17th is a mix of tiny swells under 4ft with onshore or cross-shore winds. Tuesday the 15th morning has a clean 1ft cross-off, but it’s dead. Wednesday the 16th morning is clean with a 4ft SSE swell, but the period is short at 6 seconds.

If you want a wave, point the car at that Saturday morning, September 12th. The rest is a long gap of small, messy, or onshore rubbish. Forecasts can change, but right now it’s a lean run.

Rusty.

Information about the Narrabeen-Alley Rights Surf forecast

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.
