The Lowdown

Alright, surfers, Rusty here. Let's cut through the noise and get real about the next couple of weeks. It’s gonna be a long, slow grind for waves, so don’t get your hopes up for anything epic. The ocean is going to be pretty quiet for a while.

We're looking at a stretch where there's really nothing doing for the first several days. From Wednesday the 26th through the end of the month, it's a whole lot of nothing. The swell is weak, the period is unimpressive, and the conditions are just... flat and messy. It's going to be a tough go for the first week, so if you're itching to get wet, maybe bring the log or just leave the board in the car. The S-SSW swell is there, but it’s struggling to show any real energy, with the combined energy readings limping along in the low to mid hundreds (539-882). It’s not even worth paddling out for this weak sauce.

Early next week, we see a little bump in the water. The swell pushes to around 5ft on Tuesday the 1st, but it’s still not clean. Then, on Wednesday the 3rd, we finally get something with a bit of grunt. The swell jumps to 6ft, and the combined energy gets into four digits for the first time, hitting 1008 on the morning and a solid 1422 in the afternoon. That’s the best we’re going to see, but it’s still only a marginal call with those light cross-onshore winds keeping things a little bumpy.

After that little pulse, it backs right off again from the 4th through the 10th. There’s some glimmer of hope around the 8th, 9th and 10th with a long-period swell from the SSW, with periods jumping up to 17–19 seconds, but the wave heights are just too small to make it a genuine option.

When it comes to a standout spot, we're only really looking at one place in the whole window. Trestles (Uppers) is going to be the spot, just because it's all we've got. It’s a reef and point break that’s very consistent, and while it draws in that south swell, the fact is it needs a lot more size than what’s on offer for most of this time. The one window that might be worth a look is the 3rd of September, when the swell hits that 6ft mark from the SSW. It won’t be perfect, but with a period of 12 seconds, it at least has some energy. Just be aware, crowds here are always a factor if there is anything surfable. Also, this is a week and a half away, so treat this as a promising possibility, not a guarantee.

Honestly, for the rest of the time, you're better off staying home and fixing your dings. The water temp is about average for this time of year, so no need to worry about the cold.

The long-range stuff for the second week is just too weak and unreliable to get excited about. There are some bigger period swells showing up, but they just don't have the size. It looks like one of those classic, drawn-out lulls. Here's hoping the forecasts change.

Stay patient.
