The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s on offer at Narrabeen-Alley Rights for the next couple of weeks.
Right off the bat, we’ve got a bit of a flat spell. The first real surf worth paddling out for doesn’t show up until the 7th of September. Before that, there’s a long stretch of tiny, weak waves – mostly under 2ft with short periods and poor conditions. The water’s sitting at 63°, which is about normal for this time of year, so nothing unusual there.
The standout session is the morning of the 7th (Monday). That’s when we see a solid 8ft SSE swell rolling in, with a period of 10 seconds. The combined energy is strong – 1258 – and with a clean WNW offshore breeze, it’s going to be a beautiful morning. This is a beach/sandbar setup, so that long period will keep the lines clean and offer some proper power. It’s expert territory at that size, so only for the experienced crew. The afternoon follows with 7ft SE swell and 723 energy, still very good, with a light WSW cross-off breeze keeping things tidy.
After that, the quality drops off. The 8th and 9th see smaller, choppier conditions with cross-onshore winds, so not worth getting excited about. There’s a brief window on the 11th and 12th with glassy mornings and swell around 4ft to 5ft, but the period is short (5 to 6 seconds), so the waves will be weak and messy – more of a fun paddle than a proper surf.
Later in the second week, the 13th and 14th show some promise. The 13th morning has 6ft ENE swell with glassy conditions and 339 energy – that’s a decent, clean option. The 14th morning is the pick of the second week: 6ft NE swell, 8-second period, 648 energy, and a light N cross-off breeze. It’s a long way out, so keep an eye on it, but it could be a good one.
Overall, the first week is mostly a write-off, but that 7th September morning is the real deal for experienced surfers. The second week has a couple of promising mornings, but nothing as solid as that standout.
Rusty.
