The Lowdown
Alright mate, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Right off the bat, it's a quiet start. We're looking at a pretty long stretch of small, weak surf with some tricky winds. The water temp is sitting at about 63°, which is a touch under the long-term average for this time of year—nothing to write home about, but it’s not a shocker either.
The first real chance of anything surfable shows up on Sunday morning, the 30th of August, at Narrabeen-Alley Rights. It's a beach/sandbar setup that's exposed to swell, and it's a very consistent spot. The swell is small, only 2ft out of the SE, with a period of 10 seconds. The combined energy of all swells is a weak 123, so it's not packing much punch. But the wind is glassy—a light NW breeze at 5 mph. That's a major positive, meaning the surface will be clean. It's a "surfable waves but very ordinary conditions" call, so it's a marginal option for advanced surfers only. The crowd factor here is "often," so expect a few other keen locals in the water.
After that, it's a real snooze-fest. From Sunday afternoon right through until the 12th of September, we're looking at tiny, poor-quality surf. The swell barely cracks 1ft most days, and the wind is all over the shop—cross-shore, cross-off, onshore. The energy levels are in the teens and twenties, which is basically nothing. There's a few moments with clean, offshore winds, like on the 2nd of September morning with a NW breeze at 12 mph, but the swell is just too small to do anything with. It's a blank run for sure.
We finally get a pulse of new swell on the 12th of September. Saturday morning sees 2ft from the NE, but it's a short 7-second period and the wind is onshore from the SSE at 6 mph. The combined energy is still only 45, so it's weak. The afternoon bumps up to 3ft from the SSE, but again, a short 4-second period and onshore wind. The surf is poor. Sunday the 13th isn't much better—3ft from the ESE with a 5-second period and cross-onshore or cross winds. The energy is still weak at 53.
So, the honest truth is, there's no standout session in this 16-day window. The best of a very average bunch is that Sunday morning, the 30th of August, with the glassy conditions. But it's small and only for the advanced crew. If you're a beginner, this is a total write-off. For the more experienced, the bigger days around the 12th and 13th of September have a bit more size, but the wind and short period make it a messy, frustrating affair. It might be more interesting for the kite surfers than paddle surfers on those days.
Keep an eye on the forecast, because it can’t stay this flat forever.
Rusty.
