The Lowdown

G’day, Rusty here, lookin’ at what’s on offer for Narrabeen-Alley Rights over the next sixteen days.

From now through Sunday the 14th, there is nothin’ doin’. Little waves and messy winds keep it flat and ordinary. The first worthwhile paddle is Monday the 14th morning – swell 3 ft from the NE, short period of 6 seconds, but a clean cross-off breeze from the north. Energy is weak at 153. Water temp’s 64°, about normal for the season.

Through the week it stays average. Tuesday the 16th afternoon pushes 6 ft from the SSE, energy at 481, but the wind is cross-onshore and messy – better for kite-surfing.

The absolute standout is Saturday the 19th morning. A 3 ft east swell, 11-second period – proper groundswell – energy at 242. And the wind is glassy, clean. For this beach/sandbar, that east direction and glass will set it right up. Not big, but really fun. Crowds are often here, but dawn patrol will be worth it.

After that, Sunday the 20th morning has glass again but only 1 ft. Not much.

Finally, Sunday the 27th morning – a week out – shows a 4 ft NE groundswell, 8-second period, energy at 206, with a clean cross-off. Promising but far off.

So, Saturday the 19th morning is your best bet. Everything else is small, blown out, or average.

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. 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.
