The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for Chadbourne Gulch.
We're looking at a pretty drawn-out stretch ahead, but honestly, it's not goin' to be one for the memory books. For the next week and a half, the surf is mostly small and messy, plagued by cross-onshore winds. There's a real gap in quality here, with day after day of marginal or poor conditions. The water is sitting at 59°F, which is pretty much bang on average for this time of year, so no surprises there.
The action starts off weak. Wednesday the 9th and Thursday the 10th are tiny, with swell around 2ft to 3ft from the SW. The energy is moderate at best, but the wind is mostly cross-onshore, leaving it bumpy. Friday the 11th sees a little more push, with 3ft to 4ft SW swell, but it's still those cross-onshore breezes, so it's not clean. The weekend of the 12th and 13th is nothing special either, with a bit of a shift to NW swell, though the period drops and the wind stays a problem.
Now, Monday the 14th is where things get a bit more serious, but not necessarily for the better. We get a solid pulse of NW swell, hitting 8ft. That's a short-period swell (8-9 seconds). That kind of size with that period is a choppy, powerful mess, and with the cross-onshore wind, it's going to be a real battle. This is only for experienced surfers, if anyone. The Tuesday after that drops off a bit, and we're back into the small stuff.
The real standout, the only glimmer of hope in this whole 16-day window, comes on Monday the 21st. In the afternoon, the stars nearly align. We've got a clean 3ft SW swell. The wind goes glassy. That's right, glassy. For a beginner-friendly spot like Chadbourne Gulch, that's a golden ticket. The swell is small, but it will be silky smooth. If you can get out there that afternoon, that's the moment to grab. It's the only "very good" surf forecast in the entire run.
The rest of the second week (22nd to the 24th) is a write-off. The wind howls from the NW, 12 to 22 mph, making everything lumpy and poor. There's some size on the 23rd with 5ft to 6ft, but it's blown out and ugly. Kite surfers might love that wind, but for a paddle surfer, it's a no-go.
So, to sum it up: the whole period is a flat, choppy struggle, except for a single, beautiful glassy session on the afternoon of Monday the 21st. That's your one shot.
Rusty.
