The Lowdown

G’day, Rusty here. I’ve gotta be straight with you – this next stretch is a proper dud for Narrabeen-Alley Rights. There’s no real windows of quality surf in this 16-day run, so we’re looking at a long, frustrating gap. The whole outlook is a write-off for paddle surfing, so don’t get your hopes up.

We kick off Thursday the 3rd of September with tiny 1.0ft ENE swell and a combined swell energy of just 36 – that’s weak. Cross-off winds aren’t helping, and it’s labelled as poor surf conditions. Friday the 4th is glassy in the morning with a 1ft NE swell, but the period is a short 7 seconds, so it’s gutless and messy. The energy sits at 38 – barely a ripple.

Saturday the 5th is a bit better in the arvo with a 3ft NE swell and offshore NW winds at 15 mph, giving clean conditions. But the period drops to 5 seconds, which is terrible, and combined energy is only 39. It’s surfable for a log if you’re desperate, but nothing to write home about. The rest of the first week is a mix of onshore wind, small swell, and choppy conditions. Sunday the 6th has a tiny 2ft NE swell with onshore SE winds in the afternoon, and energy at 30 – forget it.

Into the second week, things don’t improve. Monday the 7th is glassy in the morning with 1ft SSE swell and a long 11-second period, but the energy is a weak 47. That’s a tease – clean but no power. By Wednesday the 9th, we get a 5ft SSE swell in the arvo with 15 mph S cross-on winds and combined energy of 292 (moderate wave energy), but the cross-on wind makes it choppy and poor. That’s more of a kite-surfing setup than a paddle session.

Later on, Monday the 14th of September has a 4ft SSE swell with a long 11-second period, clean conditions thanks to W cross-off winds at 12 mph, and combined energy of 339 (moderate). The wave comment says “marginal” – it’s the closest thing to a standout, but it’s still just average. Then Wednesday the 16th of September arvo has a 5ft NE swell with cross-off NNW winds at 15 mph and energy of 149, but again, the period is a short 6 seconds, so it’s weak and sloppy.

Honestly, water temp is about 64°F with a 0.2°F anomaly, so it’s average for this time of year – no drama there. But there’s no quality to be found. This beach/sandbar setup needs a clean, decent swell, and we’re not getting it. The blank run is pretty standard for this area when the forecast is this flat, but forecasts can change, so keep an eye on it.

Rusty.
