The Lowdown
Alright, Rusty here. Let’s just call it how it is – the next couple of weeks are pretty flat for Narrabeen-Alley Rights. Not much worth getting wet for.
Water temp is sitting around 64°, about normal for the season.
The whole first week, from Thursday the 10th through until late the following week, is a bust. Tiny surf, messy winds, and just poor quality. There’s a clean-ish morning on Sunday the 13th with a light offshore breeze, but the swell is only 1 ft from the NE and has hardly any push (4). Not worth the wetsuit.
The dry spell runs all the way through Saturday the 19th. Swell stays under 3 ft, and most of the time the energy readings are in the weak range. Finally, on Sunday the 20th afternoon, we see a new swell: 7 ft from the SSE with an 11-second period and moderate energy (867). That’s the first real bump, but the wind is a side-on from the S at 15 mph, so it’s going to be choppy and messy. Only “marginal” at best. On a beach break, that kind of period from the SSE won’t be pretty.
Monday the 21st morning might see a slight improvement with 5 ft from the SSE (363 energy), but the wind is onshore from the SE, keeping it lumpy. After that, it fades again. Wednesday the 23rd morning might be the best we get: 4 ft from the NE, light offshore breeze from the NNE, and clean conditions. But the period is short at 7 seconds, and the combined energy is only 155 – it’s surfable but just "very ordinary."
If you put a gun to my head, I’d say the best option is that Wednesday the 23rd morning. Light crowds, clean lines from a light offshore, and waist-high plus NE windswell. It’s not a classic, but it’s the cleanest in a sea of poor options. The other pulse on Sunday the 20th is bigger but messy – only for the diehards. For the rest of you, save your energy.
Rusty.
