The Lowdown
Alright folks, it’s Rusty here. It’s a tough gig out there for the next couple of weeks. Looks like we’re in for a bit of a dry spell.
Alright, let’s be honest. The first real surf we’re looking at is a bit of a wait. The immediate outlook is pretty flat. For the next few days, we’re looking at tiny, weak waves. The swell energy is mostly in the low hundreds (213), and with a 1ft to 2ft SSW swell, you’ll be lucky to get a ripple. Couple that with onshore wind, and it’s basically a lake out there. We’ve got a gap of nearly a week with nothing worth paddling out for.
Now, the first time we start seeing something with a bit of life is around Wednesday the 7th of August. There’s a pulse of energy coming through, but it’s still small. The long period swell (19 seconds) is a positive sign for shape, but at 2ft, it’s barely going to break. The water is absolutely roasting, sitting at 76°F, which is much warmer than normal for this time of year.
The best chance to get wet will be around the weekend of the 10th and 11th of August. We’re looking at a slightly better 3ft to 3ft swell from the SSW. The real standout is the morning of Sunday the 9th of August. The combined energy is decent (443), and while the wind is a cross-onshore breeze, it’s light. The swell is a 3ft SSW at 15 seconds, which is a nice, workable groundswell for Trestles (Lowers). It’s not going to be firing, but it’ll be the most surfable it’s been all week. The line-up is always busy, so expect crowds.
Looking further out, the second week is a bit of a tease. We see some moderate wave energy building, with combined energy climbing into the 500s and 600s, but the wind keeps swinging cross-onshore. The afternoon of Friday the 14th of August has a 3ft SSW swell with a solid 18-second period and energy up at 671, but it’s messy with a moderate cross-onshore breeze. The weekend of the 15th and 16th of August also shows a 3ft SSW swell, but that same wind pattern holds it back from being a true standout. It’s promising, but not a certainty.
So, to sum it up: the wait is long, the surf is small, and the wind isn’t doing us any favors. If you’re desperate, Sunday the 9th of August is your best bet for a clean-ish session. Keep your expectations low and your board waxed.
Rusty.
