The Lowdown
Alright, Rusty here, let’s talk it through.
Look, the surf is flat. Narrabeen-Alley Rights is a beach/sandbar break that needs ENE swell, and we just aren’t getting it. The water’s about normal for this time of year, nothing crazy.
From Sunday the 23rd of August all the way through, the swell stays tiny – mostly under 3 feet, often just 2 feet or 2 feet. The wave energy is weak, readings like 31 down to 17 (combined energy of all swells directed here). It’s a long stretch of poor surf, with only a couple of sessions that are barely rideable.
The best of the bunch is Tuesday morning, the 25th of August. We get a bump to 4 feet from the NE, with a cross-offshore wind from the NNW at 9 mph. The wave energy jumps to 251 (combined energy of all swells directed here), the strongest we see. The period is only 6 seconds, so it’s a short-period windswell, not the best shape, but it’s the cleanest and most powerful window. That’s your best bet – not great, but the best on offer.
Tuesday afternoon on the 25th holds 4 feet from the ENE, with a 7-second period, and cross-off wind from the N at 9 mph. It’s surfable, but ordinary. The energy drops to 168 (combined energy of all swells directed here).
Wednesday morning the 26th has 4 feet from the NE, cross-off from the SW at 6 mph, with energy at 140 (combined energy of all swells directed here). Clean, but still very average.
After that, it’s tiny swell, often under 3 feet, with onshore or cross-shore winds, and a lot of “poor surf conditions” flags. There’s a glassy moment on Monday morning, the 7th of September, with 3 feet from the NE, but the energy is only 62 (combined energy of all swells directed here). Surfable, but barely.
This is a quiet run. The swell is small, the period is short, and the best windows are just ordinary. If you’re keen, Tuesday the 25th morning is your pick, but don’t expect much. Crowds might be around at this spot, so keep your eyes open.
Rusty.
