The Lowdown

Alright folks, Rusty here. Let's talk about the waves at Trestles (Uppers) for the next couple weeks. I gotta be straight with you—it's looking like a bit of a waiting game at this reef and point set-up.

Right now the water is sitting at a balmy 71°, which is about 4° warmer than usual for this time of year. It feels like bathwater out there.

We start on Wednesday the 19th, but don't get your hopes up. It's small, only 3ft of SSW swell, with a solid 16-second period. That long period from the south has some energy behind it (363), but the onshore 15 km/h W wind is making a mess of it. It’s cross-on and choppy, so not worth paddling out.

Thursday and Friday are more of the same. The swell sticks around 2ft to 3ft from the SSW, but we’ve got onshore or cross-on winds that are keeping things bumpy. The light winds help a touch, but the wave quality is just not there. You'll see a few days of this marginal stuff, but it's nothing to write home about.

Things stay flat and uninspiring through the weekend and into the start of next week. We're looking at a real gap here with no solid recommendations.

Now, towards the end of the month, we see a slight pulse. On Saturday the 29th of August, the swell height bumps up to 4ft to 4ft from the SSW, with period dropping to 16-17 seconds. The combined energy climbs to (724), which is a nice moderate kick. The wind is still cross-on at 10-15 km/h, so it won't be perfect, but it's the first morning that shows a bit of life. It’s still a toss-up if the tide will cooperate.

Into the first days of September, on Thursday the 3rd, the swell jumps again to 4ft from the S, with a 14-second period and a combined energy of (660). The wind is lighter out of the W at 10 km/h. It’s still cross-on, but light, so the surface should be cleaner than what we’ve seen. It’s the best looking day in the whole outlook, but it’s a long way out, so don’t lock it in yet.

Truth is, nothing in this forecast is a true standout. The swell direction is SSW to S, and this break loves a W swell, so we’re not hitting the optimum. The wind is never fully offshore, and the size stays small. It's a tough run. For the bigger days, the 4ft is still fine for most skill levels. This place is very consistent and exposed, so when it’s on, it’s on. For now, keep your board waxed and check back in.

Rusty.
