The Lowdown

Alright, this is Rusty. Let's be straight with you—this outlook for the region is a tough one. We've got a 16-day window starting now, but the pickings are slim. Let's get into it.

The first real flicker of surf comes on Thursday, July 30th, at Trestles (Uppers). The water is much warmer than normal for this time of year, sitting at 74°F.

Thursday morning sees a 5ft swell from the S, with a period of 14 seconds—that's real groundswell, packing some decent energy (combined energy of 1051). The wind is a light cross-on from the WSW at 10 mph, which is not ideal but it's light, so it's not ruining it completely. This is the strongest swell we've got in the whole run, but the wind is just off enough to keep it from being a total standout. It's a little on the bigger side for beginners, but solid for the advanced crew. Expect crowds, because this spot is always busy.

By Thursday afternoon, the swell drops fast to 3ft from the SSW with a 15-second period, and the wind swings directly onshore. It's a no-go.

Friday the 31st is similar—morning is 4ft from the S (14 sec), but with a light cross-on breeze. Afternoon drops to 4ft with a cross-on from the W. It's rideable, but nothing to write home about.

Saturday the 1st of August fades further to 3ft from the SSW, and the wind is onshore both sessions. The energy is low (338-341). From Sunday the 2nd through to Wednesday the 13th, it's a desert. Wave heights hover between 1ft and 3ft, with periods all over the place and mostly onshore or cross-onshore winds. The combined energy drops into the 100s and low 400s—weak to moderate at best. The wave comments are all "poor surf conditions" or "marginal." There's a long, painful gap of nearly two weeks with nothing worth paddling out for.

The only real standout, if you can call it that, is the first day—Thursday, July 30th, morning. That 5ft S swell at 14 seconds is the most energy we see, and at a reef-and-point break like Uppers, that long period groundswell can set up some nice lines. But the wind is a cross-on, not offshore, so it's not the cleanest it could be. It's the best of a bad bunch.

The rest of the 16 days is a write-off. For a spot that's usually very consistent, this is a depressing run. The forecasts can change, but right now, I'd leave the boards in the car.

Rusty.
