The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, I’ll be straight with you – this is a really quiet stretch. We’re looking at Trestles (Lowers), and for the vast majority of the 16-day run, the wave energy is just not there. We’ve got a solid 15 days of conditions that are basically unsurfable, with only weak to moderate energy levels at best. The combined swell energy sits in the low to mid hundreds (e.g., 233 early on Saturday, then 387, 194, 176, etc.), which tells you the ocean is just not putting any power into the lineup. The water temp is about average for the time of year, nothing unusual there.
The first real glimmer of hope doesn’t show up until Sunday, August 16th in the morning. That’s the only day that gets a whisper of a chance, rated as "marginal". Even then, we’re looking at small 3 ft of SSW groundswell with a long 16-second period, so it’ll be clean with a light breeze but the energy is still only moderate at 332. It’s a long wait for something that’s barely a surf. For a spot that’s usually very consistent, this is a real dry spell. It’s the kind of blank run that’s more normal for the area when the stars don’t align, so don’t hold your breath.
Rusty.
