The Lowdown
Alright folks, Rusty here, checking in on the local stretch. Honestly, the outlook for the next couple of weeks is a long, drawn-out session of mediocrity with one real bright spot way down the line. For the most part, we're looking at small, wind-affected lines that are just going to leave you frustrated. The water temp is sittin' around 56°, which is pretty much average for this time of year, so no surprises there.
First up, Chadbourne Gulch. We've got a little bump of swell comin' in on Wednesday the 12th, around 7ft from the NW, but it's a short-period 8-second wind swell. The combined energy is moderate (818). The wind is light offshore out of the WNW, so it'll be clean, but the quality is only marginal. It's a beginner spot, so if you've just gotta get wet, go for it, but don't expect any gems.
From there, we hit a real flat spot. Thursday the 13th through Monday the 17th is just a grind. Swell drops right off. We're lookin' at waves around 2ft to 3ft, mostly from the SSW with long periods of 15 to 19 seconds. That sounds good on paper, but the wind is mostly cross-onshore, messin' up any potential. The energy dips down into the hundreds (443-719), which is weak. There's nothin' here worth paddlin' out for. Honestly, if you're a kiter, those afternoon breezes and the small swell might be your jam, but for a surfboard it's a no-go.
Tuesday the 18th gets a bit of a pulse, but it's ugly. An afternoon jump to 8ft from the NW, combined energy jumpin' to 1020 (moderate), but it's a short-period 7-second wind swell. The wind is a moderate cross-onshore breeze at 12 mph. That's choppy, messy, and at that size, it's pushin' into expert-only territory anyway. Not worth it.
We then drift through another patch of tiny, cross-onshore slop from Wednesday the 19th through Sunday the 23rd—waves mostly under three feet, weak energy, nothin' to write home about. Just a frustrating stretch.
But here's the standout. You need to circle Sunday the 23rd of August on your calendar. That afternoon, Chadbourne Gulch looks like it will finally turn it on. We're lookin' at a solid 7ft swell from the NW, combined energy is crankin' with a strong 1138. The wind goes dead calm, with the report sayin' "glass." That's a *major* positive. That NW swell will be linin' up perfectly under glassy conditions. At 7ft, it's solid—this is for the experienced crew, not beginners. Expect some proper waves. It's a consistent break, but it can get crowded, and with a forecast like this, it will be. Get on it early.
After that, the swell fades again. Monday the 24th and Tuesday the 25th see it drop back to the 4ft to 2ft range. The very end of the outlook, Wednesday the 26th, has a tiny 2ft glassy session, which would be a nice little mellow surf for a log, but nothin' like that Sunday.
So, to sum it up: the next two weeks are mostly a bust. Save your energy, do the yard work, wash the wetsuit, and go all-in for that Sunday the 23rd at Chadbourne Gulch. That's the one.
Rusty.
