The Lowdown
Alright folks, Rusty here. Let's give you the rundown for Chadbourne Gulch over the next couple of weeks.
Honestly, it’s a bit of a bleak stretch for most of this period. We’ve got a mix of small, weak swells and light but persistent onshore breezes that’ll keep things mushy. Water temp is around 57°F, which is pretty standard for this time of year - nothing out of the ordinary there.
Your best bet in the near term is Tuesday the 11th. We’re looking at a NW swell around 6ft in the morning, with a period of 8 seconds. The energy is moderate at 680. Wind is light from the west, which is okay. It’s not going to be epic, but there’ll be something to push you around. The afternoon picks up a little to 7ft with a slightly longer 9-second period, and the energy bumps to 824. Wind stays light, but it’s a touch cross-onshore. Expect some ripples on the surface. This is about as good as it gets for the first week.
Wednesday the 12th and Thursday the 13th keep that same NW swell around 7ft and 6ft respectively, but the wind turns more cross-onshore, which will knock the shape around. It’s rideable but nothing to write home about.
Then things really taper off. From Friday the 14th through to the following week, we’re looking at a drop in size. The swell swings around to the SSW, but it’s smaller. You’ll see waves in the 2ft to 4ft range with periods varying, some of those long-period ones over 15 seconds. But the energy drops into the moderate to weak range, and the light cross-onshore winds persist. A lot of these days are marginal at best. There’s a chunk of time here, around the 17th and 18th, where it’s just poor. It looks more like a lake than an ocean. You’d be better off with a kite than a paddleboard on days like that.
Now, there is a little glimmer of hope towards the end. On Saturday the 23rd, the morning still looks rough, but the afternoon is interesting. The wind goes glassy, which is exactly what we want. There’s a SSW swell around 2ft with a long 18-second period. The energy is moderate at 445. It’s tiny, but with those clean conditions, it could be a fun longboard wave at the Gulch. That’s your standout for the second week, though as we get that far out, I’d take it with a grain of salt.
The last few days of the month see the size stay small and the cross-onshore winds return, so it’s back to the drawing board. The Tuesday the 26th afternoon does have a light onshore wind and a 2ft swell, but the energy is still moderate.
So, to sum it up: don’t get too excited for the next week or so. Tuesday the 11th is your best early call, and that’s not saying a whole lot. The real hope is that glassy, clean little pulse on the 23rd. Keep an eye on that one. It’s been a tough run, but there’s always something on the charts.
Catch you in the water.
Rusty.
