The Lowdown

Alright folks, Rusty here. Let's have a look at what's cookin' for Trestles (Uppers) over the next couple of weeks.

Right off the bat, I gotta be straight with you: the first ten days or so are a tough slog. We're looking at a pretty bleak stretch from Tuesday the 14th all the way through to late on Wednesday the 22nd. The surf is tiny, mostly around 1ft to 2ft, and the wind is a constant problem. It's either cross-on or straight onshore from the south or west, keeping that surface messy and bumpy. The combined energy is weak, never getting past a few hundred, so there's just no oomph in the water. The swell is coming from the SW, but with a super long period of 18 seconds it's a tease—it has the energy but no size to work with at a beachy setup like this. It's a write-off for anything worth paddling out for.

Now, come Sunday the 19th, things start to look a little less hopeless. The swell bumps up to 4ft, still from the S, but with a period of 12 seconds, it's a bit more of a workable wave. The wind is light onshore, so it won't be glassy, but it's no longer a total mess. The combined energy jumps to 876, which is a sign of life. This is described as "marginal," but it's the first real chance to get wet. The following Monday the 20th and Tuesday the 21st hold similar 3ft to 3ft S/SSW swell with light winds, but still cross-on. It's not firing, but it's ridable. The consistent nature of Uppers means there'll be waves, even if they're not pretty.

Then we hit the standout. Skip ahead to Friday the 24th of July. This is the one. The swell absolutely pumps up, hitting 7ft on the morning and 8ft in the afternoon from the S, with a period of 14-16 seconds. The combined energy surges to a massive 1863 and then 3118. That's proper groundswell. The downside is the wind shifts to a cross-off from the WNW in the afternoon, which is actually a decent direction for Uppers. This is a big call, but this is the best on offer. It's going to be a powerful, clean-ish wave. However, with 8ft, this is for experienced surfers only. It's going to be a handful.

The next morning, Saturday the 25th, is still pumping with 8ft swell but the wind turns back to a cross-on W, which will chop it up. The energy is still massive, but the quality drops. After that, the swell fades fast into another mediocre stretch of 3ft to 4ft SSW swell from the 26th onward, with light onshore winds. The period on the 26th is 19 seconds, which can make the wave a bit too straight and fat for a beach break, but it'll still offer some clean lines.

So, to be honest, the real standout is that Friday the 24th through to Saturday morning the 25th. That's where the size and power are. The rest of the window is either flat or marginal. Don't get your hopes up for the first week and a half, but keep an eye on that last weekend of July. It could be a proper session.

Stay frothy,
Rusty
