Alright, this is Rusty, and we're looking at the Trestles (Lowers) region. Right off the bat, I gotta be straight with you—it's a tough stretch. The first week is mostly a write-off. We've got a bit of swell on offer, but the wind is just not playing ball. It's that cross-onshore junk that's messing with the surface.

Thursday the 9th is a no-go. We've got a 3ft SSW swell pumping in with a really long 16-second period, but the wind is from the SSW, putting a nasty cross-onshore chop on it. The combined wave energy is at a moderate 641, but with that wind, it's just going to be a mess. The water temp is sitting at 68°, pretty average for this time of year.

Friday the 10th through the weekend is the same story. The swell drops to 3ft and the wind stays cross-onshore. The whole first week is just that same pattern—small, choppy, and unappealing. There's a brief moment Wednesday afternoon the 15th where the wind goes glassy, but the swell is tiny at 1ft. You might find an ankle-snapper, but it's barely surfable.

Now, if you're patient, there's a reason to pay attention to Saturday July 19th. The forecast gets interesting. The swell starts to build from the S, reaching 4ft in the morning and 6ft in the afternoon. The combined energy jumps to a strong 2412 by the afternoon. The wind is light cross-onshore from the west, which is about the best we can hope for here. This is the standout. The swell direction is solid for the break, and while it's not perfect, it's the only window of proper waves in the whole outlook. This will be a proper groundswell with a 17-second period, so expect long lines with good shape.

That swell holds into Monday July 20th as well, peaking at 7ft. However, with the swell size getting well over 8ft in the forecast for the afternoon energy, and the period dropping to 14-15 seconds, this is starting to push into expert-only territory. The wind turns onshore from the SSW, so it'll be a bit lumpy but still powerful.

After that, the swell fades fast through the rest of the week, dropping back to 3ft by Wednesday the 23rd with deteriorating winds.

So, bottom line: the first nine days are frustrating with small, choppy surf. The real action, and your only real chance for a proper session, is Saturday July 19th. That's the one to circle. The size and energy are there, and the wind is manageable. Anything after Monday the 21st is back to small stuff.

Rusty.
