The Lowdown
Alright folks, Rusty here with the outlook for Narrabeen-Alley Rights. This stretch of beach and sandbar is a regular favourite for the advanced crew – very consistent, exposed to the ENE swell, and often drawing a crowd.
The next 16 days start off flat and messy. Thursday 16th July is a write-off with fresh cross-onshore southerly wind and no measurable swell. Friday 17th morning brings a tiny 2ft of east swell at a short 6 seconds, but it’s glassy – just enough to get a wobbly one if you’re desperate. The rest of that Friday and Saturday stay small and onshore, not worth paddling out. Sunday 19th sees a jump in size to 6ft from the ENE with a solid 11-second period, but the onshore SE wind keeps it lumpy and marginal. The combined energy hits 769 (moderate-strong), but the conditions aren’t doing it justice.
Now here’s the real standout: Monday 20th July morning. The wind switches to a light offshore from the WNW at just 3 mph, glassing up clean lines. Swell holds at a solid 6ft from the ENE with a 10-second period, and the combined energy is a healthy 650. This is the best window – expect well-shaped, powerful waves with that offshore groom. The water temperature is about average for the time of year at 64°F, nothing unusual. Crowds will be typical for this break, but the quality will be worth the company.
Tuesday 21st morning stays glassy with offshore NW wind and 5ft ENE swell (period 10s, energy 472) – another good session, though slightly smaller. Wednesday 22nd morning has a cross-offshore WNW breeze and 4ft ENE swell (9s, 253 energy) – clean but dropping. After that, the size fades quickly. Thursday 23rd morning offers a brief offshore and 3ft, but it’s ordinary. From Friday 24th onward, the surf becomes tiny – under 2ft for days – and the wind turns cross or onshore, leaving little to get excited about. There’s a small bump of longer-period swell on Thursday 30th July afternoon (0.7ft, 14s) but it’s cross-onshore and choppy, not worth chasing.
Bottom line: the only true standout is Monday 20th July morning – clean offshore, solid ENE swell, decent energy. Tuesday morning is a solid backup. After that, it’s a long dry spell. Keep an eye on the forecast, but for now, pencil in that Monday session.
Rusty.
