Alright folks, Rusty here. Let's get into what's cooking for Lower Trestles.
Alright, so we're looking at a pretty quiet and choppy spell ahead for Trestles (Lowers). The water's sitting at a touch warmer than normal for this time of year, about 68°, which is a nice bonus for the early mornings.
The surf is going to be small and pretty average for the most part. Nothing really firing until we get deeper into the forecast. We've got a long stretch of poor to marginal conditions kicking off Sunday, July 5th. The swell is from the SSW, hanging around 3ft to 4ft with a decent long period of 16 to 18 seconds, but the wind is a real buzzkill. It's mostly a light to gentle cross-onshore breeze, making for choppy, messy waves. The energy is moderate, bouncing between 431 and 895 in the combined swell department, but it doesn't translate to clean, rideable faces. This continues through to Saturday, July 11th.
Now, there is one standout moment. On Saturday afternoon, July 11th, we get a window. The wind drops to nothing – completely glassy – with a 3ft SSW swell and a 15-second period. That combination of clean conditions is exactly what we need to make the most of that small but long-period groundswell. The energy is moderate at 408, but with a glassy ocean, Trestles can turn tiny waves into fun little runners. Keep your expectations low on size, but the quality should be there. After that quick moment of glory, it's right back into the cross-onshore wind and poor conditions through the middle of the month.
Looking further ahead, there's a glimmer of hope on Sunday, July 19th, and Monday, July 20th. The swell starts to push up a bit with moderate wave energy (up to 921), and the winds look a little better with light onshore or cross-onshore breezes. It’s still a long way out, so take it with a grain of salt, but it suggests the start of a building trend as we head into the third week of July.
Overall, keep your eyes on that Saturday afternoon glass-off. Otherwise, it's a bit of a waiting game.
Stay stoked,
Rusty
