The Lowdown
Alright, Rusty here. Let's break down what's cooking.
It's a quiet start, no doubt. For the first week and a half, the surf is small and the wind is mostly cross-onshore, making things choppy and uninviting. The first real window of opportunity opens up on the morning of Thursday, July 23rd.
That Thursday, July 23rd, is the pick of the bunch. We finally get a pulse of good energy. The swell jumps to about 6ft, coming from the South, with a nice 14-second period. That's a groundswell with some real power. The combined energy hits 1368, which is strong. The wind is light and variable, giving us clean, glassy conditions. This is the one to aim for. The spot is Trestles (Lowers), a consistent beach and reef break. The south swell direction isn't perfect, but with that size, period, and clean winds, it will be firing. Just remember, at 6ft, it's a step up and might be too much for beginners. And the crowds are always there, so be prepared for a full parking lot.
The water is about 69°, which is a touch warmer than average for this time of year.
After that peak, the swell backs down through the weekend to around 4ft to 5ft, and the wind goes back to the onshore, so the quality fades. There's another smaller pulse on Monday, July 27th, with a 3ft SW swell and a very long 18-second period, but the onshore wind will ruin it.
So, mark it down. Thursday, July 23rd is your best shot. Get after it.
Rusty.
