The Lowdown
Alright, let me tell you straight up, the next two weeks are lookin' pretty slim for proper waves around here. This ain't no firing season, that's for sure.
We’ve got a long stretch of small, weak energy coming in, and the best of it is honestly pretty modest. The main spot to talk about is Rincon - Rivermouth. It’s a point break that’s fairly consistent, exposed to WNW swell. Right now, we’re looking at small SSW and SW swells, mostly in the 1ft to 2ft range with some pretty long periods – 18 seconds early on. That’s groundswell, so it’ll have some shape, but the size is just so tiny it’s hard to get excited. The water temp is sitting about average for this time of year, so no surprises there.
The first real window where it might be worth paddling out looks like Saturday afternoon the 19th of September. You’ve got a 2ft SW swell with an 18 second period, and the wind goes light cross-offshore, cleaning things right up. The combined energy sits at 219 (moderate), which is about as good as it gets in this run. It’ll be tiny, but glassy and lined up. Still, for the size, it’s more of a longboard or foiling wave than a proper shortboard session.
Monday afternoon on the 21st is another similar one – 2ft SW at 17 seconds, light cross-off wind. The energy’s up a touch at 239. Again, small, but clean. If you’re after the best of a bad bunch, these afternoons are your pick.
There’s a real gap from the 22nd onward where the wave energy drops back into the 100s, the swell period slowly shrinks, and mornings are plagued by cross-onshore or cross winds. The afternoons stay cleaner with those cross-off breezes, but the surf stays marginal and ordinary.
The standout, if you can even call it that, would be the Saturday afternoon the 19th and Monday the 21st at Rincon - Rivermouth. The winds are good, and the consistency is there for a point break. But don't expect any size at all – this is a micro-swell window. Crowds are likely at this spot, especially when it’s clean.
So, bottom line: don't book time off work. We’re in a long, quiet patch. Keep the wax warm and hope the forecasts change. It can’t stay this flat forever.
