The Lowdown
Alright, let's get into it. This is Rusty, and I'm looking at the next couple of weeks for us.
To be honest, it's a slow start. We're looking at the first week of August and there's just nothing doing. Thursday the 6th through to the end of that first week is a real write-off. Tiny, weak swell and the odd bit of onshore crud keeping things small and messy. Don't bother checking the cam until the second week.
The first real pulse of hope comes in on the second weekend. Saturday the 15th of August shows a little bump with a light WSW breeze, giving us a clean look at some small lines from the east. It's not going to be a world-beater, but it's a start.
Now, the real standout in this whole forecast is Sunday the 16th of August. And I mean, *standout*. Narrabeen-Alley Rights is set to fire. We're talking a solid 8ft of swell from the ESE, pushing in at a nice 11-second period. That's some proper groundswell energy. The combined energy of all swells is a massive 1452, which is impressive. But the best part? Glassy conditions, mate. Flat calm. That's a rare treat. Clean, peeling sandbar waves for the experienced surfer – this is a bigger day, so leave the foamboards at home.
Monday the 17th might look tempting with 10ft of swell, but that's too big for this break. It's going to be a washing machine. Only for the absolute lunatics, and even then, it's a risk.
We've got a little drop-off but then another solid window opens up. Tuesday the 18th of August is looking prime again. 6ft of swell from the ESE, and once again, glassy conditions in the morning. Combined energy is a very healthy 712. This is a much more manageable size for a good crew of surfers.
Then Wednesday the 19th of August brings another glassy morning, again 6ft from the ESE, with strong energy at 844. These mornings are the pick of the bunch. The afternoon gets a bit choppy but the morning windows are gold.
Thursday the 20th of August holds the pattern: 6ft of clean swell from the ESE under a light offshore NNW breeze. Another solid morning session on the cards. The energy is at 807. This is a fantastic run of days.
Keep in mind, this is a very consistent spot, and it's exposed to the east-northeast, which matches the swell direction perfectly. Crowds are often a factor here, so get in early for those glassy windows.
The final Friday the 21st of August tapers off a bit, with 4ft of clean swell under a light offshore cross-off breeze. A good way to end the run.
So to sum it up: forget the first week. The big story is the run from Sunday the 16th through to Thursday the 20th of August, with the glassy mornings on the 16th, 18th and 19th being the absolute cream of the crop. Get stoked.
Rusty.
