The Lowdown

G’day, Rusty here again. Let’s run through the same outlook but in feet and Fahrenheit for the Yanks.

Alright, for Narrabeen-Alley Rights (beach/sandbar), it’s a pretty slow 16 days ahead. Don’t rush down there right now.

The first few days are a bust. Monday the 24th has a weak, short-period windswell at 4ft from the NE with a sloppy cross-breeze. Tuesday the 25th morning brings a bit more size at 6ft from the NE, and the NNW cross-offshore wind cleans it up, but the period is short (7 seconds), so it’s only marginal. Combined energy is moderate (422). After that, it shrinks and gets onshore again. Wednesday through Thursday is small and blown out.

Then we get a real slice of goodness. Friday morning, August 28th – it’s glassy, with a light WNW breeze, a 2ft swell from the SSE, but the period is 11 seconds, giving it some real shape and push. Energy is moderate (176). It’s tiny, but it’s the cleanest surf of the whole period. That same glassy, small setup repeats Sunday morning, August 30th – light NNE, a similar 2ft SSE swell, moderate energy. Both mornings are your best bet for a fun little session.

From Monday 31st August, things go flat. Waves drop to around 1ft or less, with mixed directions and onshore wind. A few days have offshore or glassy wind, but there’s hardly any wave to ride – energy often below 100 (weak). This quiet stretch runs for over a week.

There’s a small bump on Saturday 5th September morning – 3ft SSE swell, period 11 seconds, combined energy at 624 (moderate). But the wind is onshore, so it’s messy. This setup might suit kite surfers more than paddle surfers.

The standout pick is still Friday morning, August 28th – glassy, clean, with that longer-period 2ft SSE swell. It’s small, but it’s your cleanest option. Sunday morning, August 30th is the same vibe.

Water temp is 64°F, about 0.7°F cooler than average – pretty standard for this time of year.

So, it’s a quiet outlook for Narrabeen-Alley Rights. A couple of tiny, glassy mornings are the only real highlights. The rest is flat or messy. Might be worth giving it a miss unless you’re after a small, clean paddle.

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.
