The Lowdown

Alright, let’s have a look at what’s on the cards for the next couple of weeks. First up, the water’s sitting at 63°, which is pretty much spot on for this time of year, nothing wild there.

To be honest, the next week and a half is looking pretty flat and messy. There's a small pulse of ENE swell around 3ft on Sunday the 9th, but the wind is all wrong – cross-off and messy. You'd be scratching for a shin-high wave. Monday the 10th sees a jump in size to 7ft with a stiff NW offshore, but the energy is moderate at best, and it looks like it's just going to be blown-out and hard to paddle into. That’s a day for the experienced crew only, and even then, it’s questionable.

From Tuesday the 11th through to the 18th, the surf basically dries up. We're looking at wave heights dropping below 3ft, with periods dropping and winds swinging onshore. The energy numbers are in the weak to moderate range, but the quality just isn’t there. It’s a real blank stretch for a solid week. You’d be better off doing anything else. The swell direction stays from the ENE, but it just doesn’t have any push.

Now, here’s where it gets interesting. Thursday the 20th of August starts to wake up. We’ve got a solid 7ft of ENE groundswell rolling in, with a period of 9 seconds and a strong jump in energy. The wind is light and cross-shore, which might make it a bit lumpy, but there’s definitely size. But the real standout is Friday the 21st of August. That morning is the pick of the whole run. You’re looking at 6ft of ENE swell, period pushing 10 seconds, and a light NW cross-off breeze with clean conditions. The energy is strong. This is the day to clear the schedule. Narrabeen-Alley Rights is the only break on the list, and that morning is going to handle this swell well. It’s an exposed beach/sandbar, so you know it’ll be handling the power, and the offshore wind is going to make it clean. Crowds are often a factor here, so get in early.

The weekend after that (22nd and 23rd) still has decent size – around 6ft – but the winds get a bit cross-y and fresh, so it won't be as perfect as that Friday. After that, it looks like it fades out again by Monday the 24th. So, if you can only get one surf in over the next two weeks, make it Friday the 21st morning. It's not a super long-period groundswell, but the size, direction and wind all line up. The rest of the window is pretty much a write-off.
