The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Trestles (Lowers).
Honestly, I gotta be straight with you – the next two weeks are looking pretty flat and frustrating. This is a spot that usually pumps, but right now we’re in a real dry spell. The first solid chance of anything rideable doesn’t pop up until Thursday the 13th, and even then it’s marginal at best. You’re looking at a gap of a few days with basically nothing on offer before that.
The water is a wild story though – it’s sitting at a balmy 75°F with an anomaly of 8°F, which is way, way warmer than normal for this time of year. You’ll be surfing in a bathtub.
For Thursday the 13th morning, we finally see something. A small SSW swell around 2ft with a period of 16 seconds is pushing in. That long period gives it some punch for the size, but the combined energy is only moderate at 340. Winds are a light onshore from the SW, keeping it a bit lumpy. The call is marginal, just a 1 out of 10 kind of day. It’s tiny, and the onshore flow won’t help.
The rest of the forecast is a long stretch of poor to marginal conditions. Friday the 14th morning shows a similar 2ft SSW swell, but the wind is from the WSW, again onshore. We see the energy creep up to 535 (moderate), but the quality just isn’t there. Saturday the 15th afternoon shows a slight bump to 4ft from the SSW with 16-second periods and energy hitting 714, but the wind is coming straight from the WNW, which is cross-shore and messy at Lowers. That’s a 2 out of 10, and it’s the best score in the whole 16-day window, which tells you everything.
Sunday the 16th morning has a 4ft SW swell with 16 seconds and moderate energy at 575, but again, a cross-onshore breeze from the WSW keeps it from cleaning up. After that, it’s all downhill. The swell drops back down to 1ft to 3ft for the entire second week. The energy stays weak, between 165 and 464. There isn’t a single standout session in this whole run. The wind is mostly cross-onshore, and the waves are just too small and weak to do anything fun on.
Honestly, for experts paddling out here, this stretch is a write-off. There’s no big swell, no clean glass, and no hope of a real session. If I’m being honest, with these onshore winds and weak swell, this setup looks more interesting for a kite surfer than a paddle surfer right now.
Keep your board in the car and check back next week – it won’t be this bad forever.
Rusty.
