The Lowdown
Alright, Rusty here. Let’s talk about Chadbourne Gulch.
Alright, listen up. The next couple of weeks are a bit of a mixed bag here at Chadbourne Gulch, with a real standout window around the middle of the month. The overall pattern is a slow start, then a solid pulse of swell, followed by a long stretch of small, clean conditions.
The water’s sitting at about 59°F, which is pretty much bang on average for this time of year, so nothing weird going on there.
We’ve got a bit of a wait for the first real action. The first few days, from Friday, August 7th through Sunday, August 9th, are pretty marginal. There’s a tiny 2ft to 2ft SSW groundswell with a long period on Friday, but the wind is messy. It’s not worth paddling out for.
The real action kicks off on Monday, August 10th. The swell jumps to 7ft from the NW with a 9-second period, and the combined energy hits 930 to 1187. It’s a moderate energy pulse, but the wind is a light cross-on, so expect some bumps. On Tuesday, August 11th afternoon, it gets interesting. The swell hits 10ft from the NW, and the wind goes glassy. That’s the standout. The combined energy is a strong 2237, which is proper. But honestly, 10ft is big for this spot. It’s expert territory. The swell is too big for beginners, and the long period with that size might make it a bit of a handful at a beach break, but if you’ve got the skills, that Tuesday afternoon window is the best on offer.
The rest of that week, Wednesday the 12th through Friday the 14th, sees the swell backing off from 7ft to 4ft, but the wind stays mostly cross-on or onshore, so it’s not great. There’s a little 2ft, 19-second SSW groundswell on Friday afternoon, but it’s tiny.
Then we hit a long, quiet stretch. From Saturday, August 15th, through Tuesday, August 19th morning, the swell barely breaks 3ft, mostly from the SSW with a long period. The wind is light, but it’s mostly cross-on. There’s a gap of several days with no real good surf. The energy is weak, around 385 to 678.
The next hint of something comes on Wednesday, August 19th. The swell builds to 5ft to 5ft from the NW with a 13-second period, and the combined energy jumps to 1459. That’s a moderate-to-strong pulse. The wind is light offshore in the morning and glassy in the afternoon. This is the second standout. It’s a solid, clean NW groundswell, but it’s still a week and a half out, so keep an eye on it. Promising but less certain.
After that, it drops off again. The last few days, from Thursday, August 20th to Saturday, August 22nd, are mostly small, with the swell around 2ft to 3ft. The wind is light and glassy on Saturday the 22nd, so it’ll be clean, but the waves are tiny. Good for a log, maybe.
Chadbourne Gulch is fairly consistent, so these flat spells won’t last forever. The standout is definitely Tuesday, August 11th afternoon for the experts, and Wednesday, August 19th is a solid second option for the more confident crew.
Rusty out.
