The Lowdown
Alright folks, Rusty here. Let’s get into it. The next 16 days are a bit of a mixed bag, but we’ve got a few moments where it all comes together. The water is sitting at a balmy 72°F – that’s a solid 6°F warmer than usual for this time of year, so you’ll be leaving the full wetsuit at home.
The opening stretch is lackluster. We’re looking at small, choppy conditions with a cross-onshore breeze keeping things messy. The combined swell energy is moderate at best (928), but it’s just not clean enough to get excited about. Friday the 24th through the 26th is a write-off with tiny, weak waves.
Things start to tick up a little around Monday the 27th. The swell bumps up to 4ft from the SSW, with a period of 18 seconds – that’s a proper groundswell. The wind is light and onshore, which is a shame, but the energy is there (1151). It’s still not the best, but it’s a step up. By Tuesday the 28th we’re holding steady with similar 4ft SSW swell, but the wind is still light and onshore. It’s frustrating.
The real standout window fires up on Friday the 31st of July. We’ve got a solid 6ft swell from the S, with a period of 14 seconds. The combined energy jumps to 1330 – strong stuff. The morning looks best with a light offshore wind from the WSW. That’ll clean it right up. Trestles (Lowers) is where you want to be. It’s a very consistent spot, and with that SW optimum direction aligning perfectly, it’s going to be running. Expect a long-period groundswell, which means those long, lined-up waves at this point-and-reef setup. It’s an advanced wave, but for the experienced crew, this is the best call of the window. Keep in mind, it’s always crowded here, so get in early.
Saturday the 1st of August is still decent, with 6ft from the SSW and a light onshore breeze. The energy is still up (1176), but it’s a level down from Friday. After that, the swell drops away fast. Sunday the 2nd sees the size drop to 4ft, and by Monday the 3rd we’re back to tiny, weak, poor surf. The combined energy plummets (170). The rest of the first week of August looks flat and forgettable, with nothing over 2ft and a cross-onshore wind. It’s a long, quiet run.
So, the clear winner is the end of July. If you can only get one session, make it Friday the 31st at Trestles (Lowers) with that morning offshore wind.
Rusty.
