The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for Chadbourne Gulch over the next couple of weeks.
It’s a bit of a slow start, to be honest. The first few days are pretty uninspiring, with small, weak swell and partly onshore winds. The water's sitting at just under 55°, which is about two and a half degrees below where you'd expect for this time of year, so you'll want that extra rubber.
The real standout window looks like Tuesday, August 18th. That afternoon, the wind is set to go glassy with a clean 3-foot SSW groundswell. The combined energy is moderate, but with those conditions it's going to be smooth and nearly perfect. For a beginner-friendly break, you couldn't ask for much more than that. Just be mindful that crowds are sometimes a factor here.
Later in the run, on Saturday, August 22nd afternoon, another glassy window pops up. This time with a 5-foot NW swell. It's a little more size, but the same clean conditions. Again, that's going to surf real nice for a point break. The water temp will be a bit chilly, but if you're rugged up, it's worth the paddle.
After that, the forecast gets a little more mixed and a few of the bigger swells later in the second week are paired with less-than-ideal winds or the swell period is too short, keeping things a bit ragged. We're looking at a lot of marginal calls from the 23rd onwards through to the 29th, so keep your expectations in check. There's a bit of energy on the 27th and 28th, but the wind isn't playing ball for that peak quality. It's rideable, but not the standout sessions those earlier glassy windows promise.
Stay keen, and keep an eye on the sky.
