The Lowdown
Alright, Rusty here, givin' you the lowdown in feet and miles per hour.
So here's the deal. The window starts with some heavy, proper surf, but then the ocean's gonna switch off for a long stretch. The one day to circle on the calendar is right at the start.
Sunday the 6th is your golden ticket at Trestles (Lowers) . We're talking a clean 6-foot swell from the south, with a 14-second period on the Sunday morning. That's a solid long-period groundswell, and the water's at 74°, which is a ridiculous 6° warmer than normal--super unusual, feels like a bath. The combined wave energy is strong, sittin' at 1304, so it's got plenty of power. The wind goes light and offshore from the north-northeast at 12 mph for the afternoon, so you're looking at glassy, clean conditions. This is classic Trestles. It's an advanced wave, and at 6-foot, it's on the bigger side, so it's mainly for the experienced crew. The crowd is always packed, just so you know. The morning's clean, but the afternoon with that offshore breeze is absolutely pristine. That's your standout.
Monday the 7th is still rideable, with 6-foot in the morning, but the wind turns cross-shore from the west-northwest at 9 mph, puttin' a little texture on it. Not as clean as Sunday, but there's still a few to be had. By Monday afternoon and into Tuesday, it starts falling apart. The wind gets messy and the swell starts dropping.
After Tuesday the 8th, we hit a dead zone. From Wednesday the 9th all the way through to Monday the 21st of September, it's looking real grim. The swell just vanishes, with wave heights barely scraping 3 feet and the energy numbers dropping into the low hundreds or even the two-hundreds--that's weak sauce. The wind is onshore or cross-onshore the whole time, so it's just choppy grovel. There's a tease of a super-long-period 17-second and 18-second groundswell around the 10th and 14th, but the wave heights are too tiny and the wind's all wrong to make anything work. It's not gonna be worth paddling out for weeks. This lull runs about 13 days of pretty much nothing.
So, the word is: go all in on Sunday the 6th at Trestles, morning or afternoon. After that, wax the boards and wait for the next real swell.
Rusty.
