The Lowdown
Hey folks, Rusty here. Let’s get into what’s on the table for Chadbourne Gulch. This spot is a beginner-friendly, fairly consistent beach break, and it’s got a bit of a mixed bag over the next couple of weeks.
The water temperature is sitting at 59°F, which is about average for this time of year, nothing crazy there.
The early part of the window is a bit of a tough go. Saturday afternoon the 8th kicks off with a 6ft NW swell, but the period is a short 7 seconds and the combined energy is weak (576). The wind is offshore, but the forecast is calling it marginal. Sunday the 9th sees a bigger pulse of 8ft NW swell by the afternoon, but again, a short period and the energy is still moderate (1085). The wind goes cross-on in the morning, so it’s not clean.
The first real standout comes on Monday the 10th, in the afternoon. That’s when we get a 7ft NW swell, with a 9-second period, and the combined energy is moderate (939). The wind goes glassy, which is a massive positive. The waves will be clean and well-shaped for a beginner spot. This is the best early call.
Tuesday the 11th and Wednesday the 12th also have glassy afternoons with similar 7ft and 6ft NW swells, offering more clean conditions, but the energy is a touch lower. Good for a paddle on those days.
There’s a bit of a lull from the 14th through the 17th. The swell drops to 3ft to 3ft, though there’s a glassy window on Saturday the 15th afternoon with a very long period 16-second SSW groundswell. That’s a long period, so it’ll be a bit more lined up, but the energy is moderate (610). Worth a look if you’re keen.
The second week gets a bit more interesting. Saturday the 22nd afternoon has a solid 8ft NW swell, but the period is short again at 7 seconds, and the energy is moderate (827). The wind is glassy though, so it’ll be clean. That’s a promising one, but being a week and a half out, keep an eye on it.
Overall, the best bet is Monday the 10th afternoon for the cleanest combo of size, shape, and glassy conditions. The 22nd afternoon is a long-range standout if it holds.
Stay stoked.
Rusty.
