The Lowdown

G’day, Rusty here. Look, I’ll be straight with you—this 16-day stretch for Narrabeen-Alley Rights is a tough one. We’re talking a long, flat start with hardly a wave worth paddling for. The first sign of anything rideable doesn’t show up until Sunday the 9th, and even then it’s pretty ordinary. The break is a beach/sandbar setup, so it needs a bit of love from the swell and wind gods, and they’re just not playing ball for most of the run.

The tale starts on Saturday the 8th with tiny 1ft SSE swell and a 9-second period, weak energy (49), and a cross-off wind that’s trying, but the surf is just poor. Absolutely nothing to get excited about.

Sunday the 9th sees a little bump up to 3ft from the ENE, still with a 9-second period, and the energy climbs to a moderate 163. The wind swings to a light offshore on the Sunday afternoon session, which cleans things up a fair bit. It’s described as “surfable but very ordinary,” and honestly, that’s the best label we get for a while. Crowds can be likely here, and with conditions this marginal, it’s not going to be a standout.

The only real interest comes in on Monday the 10th. The swell jumps to 7ft from the ENE in the morning, period still 9 seconds, and the energy hits a strong 766. The wind is a fresh offshore from the NNW, so the wave faces will be clean. But at 7ft, that’s expert territory—too big for beginners. The afternoon drops to 6ft but the wind is a strong offshore (25 mph), which makes it hard to even paddle into. It’s a “marginal” call, and the power is there, but the setup is tricky for a beach break. This is the best on offer, but it’s more of a challenge than a classic day.

After Monday, it’s a slow fade. Tuesday the 11th is back to 3ft with weak energy, and from there, the rest of the 16 days are a mix of tiny swells, cross-on winds, and poor conditions. There’s a brief uptick around the 22nd and 23rd of August—5ft on the 22nd morning with a 6-second period and 286 energy, but it’s a short-period slop, and the winds are cross-onshore. The 23rd morning is 3ft with a clean light cross-off, but it’s still “very ordinary.”

Water temp is sitting at 63°F, which is about 2°F below average for this time of year—so pretty normal, nothing to write home about.

Overall, the standout is Monday the 10th, no doubt. If you’re an expert and can handle the strong offshore wind and the size, there’s some power to be had. But it’s not a beginner’s day. The rest of the window is a long blank run for any decent surf. For a spot that’s usually very consistent, this is a surprising quiet spell. Forecasts can change, so keep an eye out, but as it stands, this is a lean period.

Rusty.
