Cape Mendocino Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s cut through the noise and get down to what matters. We’ve got a 16-day window ahead, and I’ll be straight with you: it’s a mixed bag of frustration and promise. Don’t get too excited for the next week, because conditions are going to be fighting us. But there are a couple of windows where it could all line up.

The first stretch, from Wednesday the 9th through Friday the 11th, is pretty rough. We’ve got swell, but it’s being chopped up by a solid cross-shore breeze. The energy is moderate, sitting around 328 to 713, but that doesn’t mean much when the surface is blown out. Cape Mendocino will be a mess, with lumpy conditions and poor surf. We’re looking at the 2ft to 3ft range, so there’s something moving, but it’s not clean enough to be fun. This is one of those times you’re better off finding something else to do.

Then, we get a reprieve on Saturday morning, September 12th. The wind dies, it turns glassy, and the ocean cleans up. That’s your first real window. There’ll be a 3ft SW swell with a 14-second period, and the energy bumps up to 732. It’s not huge, but it’ll be clean. Cape Mendocino is exposed and picks up that SW groundswell well. This is an advanced spot, and the light winds will make the paddle out a bit easier with those longer gaps between sets. Still, with 3ft and that longer period, it’s not going to be a wave count, but the quality will be there. This is probably the best wave-to-crowd ratio you’ll find in this first batch.

After that morning, the wind picks up again and we're back to cross-shore chop for the rest of the weekend. The swell fills in a bit, hitting 5ft and 6ft by Sunday, but that fresh breeze will ruin it. We’re back to poor conditions.

Then we hit a bit of a lull from Monday the 14th through Tuesday the 15th. The swell drops right out, down to 1ft to 2ft, and the energy fades to between 199 and 355. Combined with the wind, it’s about as bad as it gets. This is a real dead period.

Now, keep your eyes on the second week. Things start to get interesting around Wednesday the 16th. The wind goes light, and the swell starts to build again. By Thursday morning, September 17th, we have a standout window. The conditions turn glassy with a 6ft NW swell and a 9-second period. The energy is solid, hitting 657. This is going to be the pick of the whole run. Cape Mendocino will be handling the NW swell well, and those clean conditions are a huge plus. It’s a bit bigger, 6ft is getting more serious, but for the advanced crew, this will be the one to circle. The winds stay light through Friday the 18th, with swell holding at 5ft, so there’s potential for a couple of good sessions. But remember, these longer period swells are prone to breaking a bit straight at beach breaks; Cape Mendocino is exposed, so it could be a bit full-on, but the clean conditions should help.

We get a final little tease on Sunday morning, September 22nd, with light winds and a 3ft SW swell. It’s not big, but with that glassy surface, it’s worth a paddle. The energy is moderate at 434. We’re right back to more cross-shore wind in the afternoon, so don’t sleep in.

So, to wrap it up: the start of this run is a write-off. You’ve got one decent morning this Saturday, but the real deal is next Thursday and Friday. That’s the best quality and size combination you’re going to get. The long-range stuff is promising, but we all know forecasts can change. Keep your fingers crossed.

Rusty out.
