The Lowdown
Alright folks, Rusty here with a look at what’s coming down the line. We’ve only got one spot really worth talking about in this whole 16-day window, and that’s Trestles (Uppers).
The overall pattern is a bit of a bummer, honestly. There’s a glimmer of hope in the first few days, but then it drops right off. After a very brief run of surf, we’re looking at a huge gap of dead-flat nothing from August 1st all the way through to August 13th. It’s a proper dry spell.
Wednesday July 29th afternoon is where it’s at. The water is sitting at a toasty 73°F, which is a good six and a half degrees warmer than normal for this time of year – that’s really unusual. We’ve got a 4ft SSW swell rolling in with a beautiful 16-second period. That’s proper long-period groundswell. The combined energy is solid at 719 (moderate), and the wind is a light WSW breeze that is blowing *on* the shore at only 6 mph. It’s glassy enough, but because the wind is directly onshore, it’s not going to be the cleanest it could be.
Thursday July 30th morning brings a pulse of swell from the south at 5ft, a little bigger, but the period drops to 14 seconds and the wind stays onshore. The energy jumps to 1052 (moderate-strong), but it’s still a bit bumpy. Friday looks smaller and cross-on, while the weekend into the next week is basically a write-off for surfing.
That Wednesday is your best shot. It’s an advanced spot and it’s very consistent, which is a good thing. But, being Trestles, crowds are *always* an issue. The swell direction is SSW, which isn’t quite the optimum west direction, but the long period and decent size will still offer some long, workable walls.
The long-range stuff around August 7th to 13th shows some pulses of swell with long periods (18-20 seconds) but the heights are tiny, mostly under 3ft. The wind is messy or onshore, and the wave comments are all "poor" or "marginal." It’s not worth getting excited about until we can get a better look closer to the time.
That’s the story. A couple of slim pickings early, then a long stretch of flatness.
