The Lowdown
Alright, folks, Rusty here. Let's cut to it. The surf outlook for the next couple weeks is honestly a bummer. We are looking at a long stretch of small, gutless, and mostly crummy wind swell. If you're jonesing for a wave, you might find a sliver of hope, but don't get your hopes up for anything with any real power. This is a classic flat spell.
The water's sitting right around 85°, which is pretty much what you'd expect for this time of year.
Our first tiny grain of hope shows up on Saturday the 8th. There's a little pulse of east-northeast swell around 3ft, but a moderate cross-onshore breeze is going to make it lumpy. The energy is weak to moderate (119), but it's still not a good surf day. It's a poor surf day, no two ways about it.
Then it's back to nothing. From Sunday the 9th all the way through to Saturday the 15th, it's a total wasteland. We're talking knee-biters under 3ft, with periods of just 4 or 5 seconds. The wind stays mostly onshore or cross-onshore, chopping up whatever little ripple is there. There isn't one single window in that whole stretch that I'd even tell a grom to bother with. It's flat and it's messy.
There's a moment on the morning of Sunday the 16th where the wind drops out completely and it goes glassy. But with a swell of only 1ft and a short 5-second period, it's still hopeless. You might catch a knee-high slop if you're lucky, and it will look pretty, but there's nothing to ride.
Moving into the second week, starting Monday the 17th, we finally see the wind turn offshore. The mornings on the 17th and 18th have a light west-southwest breeze and the ocean will be clean. But again, we're dealing with tiny swells around 2ft. The energy is weak, with values in the low 20s. It's going to look glassy and inviting from the sand, but it's still very small and lacking any punch. It might be a fun longboard session if you just want to get wet on a clean face, but the paddle is likely to be more work than the ride.
So, the long and short of it is: there are no standout days, no real swell on the horizon. The Jetty is usually a consistent spot, but this kind of blank run happens. It won't stay poor forever, and forecasts can change, so keep an eye on it. But right now? The board is staying in the car.
Rusty, out.
