Alright folks, Rusty here, looking at the Trestles (Uppers) stretch for the next couple of weeks. Gotta be straight with you – it’s a pretty grim run ahead. We’ve got a long stretch of small, onshore-affected surf that’s gonna make you work for scraps.
Right off the bat, the pattern’s looking tough. There’s a real drout of quality surf for the best part of a week. The first real glimmer of something barely rideable comes around Monday July 6th. Even then, we’re looking at marginal surf with some questionable tide combos. The swell is coming from the SSW with a modest 3ft, and a period of 16 seconds. The combined energy is moderate but rising (527), but the morning wind is a light offshore from the WSW, which is a plus for clean conditions if you’re patient.
Tuesday July 7th sees a tiny bump. The swell holds from the SSW at 4ft, with a period of 18 seconds – a nice groundswell, but tricky for a beachy setup. The morning looks good with a light offshore from the SW, and the energy is solid (838). This is probably the standout window of the whole outlook. Clean conditions with that light wind and a bit more push. It’s not huge, so it’s fine for a range of skill levels. Remember, Trestles is a reef and point, so that long period should wrap in nicely.
After that, it just fades away. Wednesday July 8th through the rest of the week is back to marginal at best, with onshore winds and dropping energy. The weekend of July 11th–12th has some light wind mornings with 3ft SSW swell, but the energy dips and there’s not enough push to get excited about.
Looking into the second week, it’s more of the same. From July 13th onwards we’re seeing small SW swell, periods dropping into the 13–18 second range, but the energy levels are on the decline, mostly in the low-to-mid 200s to 300s. Light offshore winds are common, which is a minor mercy, but the swell just isn’t there. The water temp is sitting at 69°F, which is a touch warmer than normal for this time of year, so at least you won’t freeze waiting for a wave.
Honestly, if you’re looking for a paddle, the Tuesday July 7th morning window is your best and only real bet. Otherwise, the conditions are better suited for a kite if the wind picks up, because the waves are too small and weak for a worthwhile surf session. The forecast can always change, but for now, stay patient.
