The Lowdown
Alright crew, Rusty here again. Let's chat about what's on the cards for Chadbourne Gulch, but in feet and miles.
It's a slow start. The first few days are just plain ugly with the wind and chop. We're getting some small swell, but it's not clean enough to get excited about.
Keep your eyes on Thursday afternoon the 3rd. That's the real highlight. We're looking at a head-high swell, about 6ft, coming from the WNW. The wind goes glassy, dead calm. That's the key. It's a groundswell with a 10-second period, so it'll have some good energy (875). It's going to be clean, smooth, and fun for the intermediate to experienced surfer.
Friday morning the 4th is another option. It's a bit bigger at 6ft from the NW with a bit more power (1380), but the wind is onshore, so it'll be blown out. Not the best.
Then, hold onto your board. On Thursday the 10th, we get a massive 10ft swell from the south. The energy is right up there at 2468. With a short period, it's going to be a big, dumping, and unpredictable closeout. This is expert-only territory. I'd steer clear unless you're a seasoned charger.
After that, it's a two-week-long wait for more clean waves. The afternoon of the 17th has a nice, clean 5ft swell from the NW with glassy conditions (735). A good way to end the forecast, but the real magic is on the 3rd.
Don't sleep on Thursday the 3rd. That's your wave.
Rusty out.
