The Lowdown

G’day, I’m Rusty. Let me tell you straight: this 16-day stretch at Narrabeen-Alley Rights is pretty grim for a wave. There’s a big gap of nothing surf-worthy right at the start, so don't even bother checking the ocean for the first week or so. From now right through until Monday the 7th, it’s all tiny junky swell with lousy conditions. We’re talking barely a ripple, short-period slop, and no energy to speak of. You’ll have to wait nearly a full week before anything even gets your attention.

The first real flicker of hope comes on Monday afternoon the 7th. A chunk of new swell pushes in – 6ft from the NE with a short period of 7 seconds. It’s shifty and a bit fat for the beach, but the wind is clean offshore from the NW, and that’s what saves it. The combined swell energy hits 421 (moderate energy, actually), so there’s some grunt. This is the standout window for the whole outlook. If you’re an advanced surfer and you’ve got a short board, Tuesday the 7th afternoon is your best bet. After that, it fades fast.

Tuesday the 8th sees the swell drop back to 4ft from the NE, still with a clean cross-off wind, but the energy is down to 176. It’s okay, but nothing to rave about. By Wednesday the 9th, it’s back to tiny waves again, and you’re staring at another long lull right through to Sunday the 13th. On Sunday the 13th, there’s a small pulse of 3ft from the NE (period 6-7 seconds) and light offshore winds; the energy is only 63-65. It’s “surfable but very ordinary,” as we say – a one-out session if you’re desperate. Beyond that, the second week brings a few more small, messy days with a bit of southerly chop, but nothing that’s gonna get the heart pumping.

The water temperature is about average for this time of year, no big anomaly to talk about.

Don’t expect any crowd here – with surf this lousy, you’ll have the place to yourself. That’s the only silver lining.

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.

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.
