The Lowdown
Alright, listen up. Right now, the ocean’s flat and ugly. Monday morning you’ve got ankle-biters at Sebastian Inlet-First Peak, but it’s poor. Water temp is about 84.6°F, which is pretty normal for this time of year, so nothing wild there. But honestly, there’s nowhere to go.
We’re looking at a long stretch of junk through the middle of the week. By Wednesday, the swell bumps up a little—maybe chest high—but the wind is howling onshore at 19 mph from the NE and it’s just a mess. The energy is moderate, around 198 to 208, but it’s short-period windswell. Not worth the paddle.
Thursday stays poor, with the wind easing a touch but still cross-onshore. The swell hangs around 4ft, but it’s still short-period and choppy. Friday morning looks a bit cleaner with a light NE wind and a little more shape to the 3ft waves, but it’s still not a standout.
Here’s the deal: from Monday through most of next week, the surf is just not there. There’s a long, dry spell from the 14th all the way through the 24th. Sure, there are waves, but they’re all poor. This is a drought, plain and simple.
Now, the one window that’s got some life. On Friday the 25th, we finally see a change. The morning is clear, the wind drops to a light offshore from the S at 6 mph, and the swell comes up to 4ft from the NE with a period of 8 seconds. The energy’s moderate, around 218, and they’re calling it “expect good surf conditions.” That’s the one. It won’t be huge, but it’ll be clean and there’s some push. That’s your best bet of this whole stretch.
The weekend after—Saturday the 26th—has similar size, around 4ft, but the wind goes onshore again and it just gets messy. The following week starts to pick up more energy, with Tuesday the 29th showing a bigger pulse of 4ft from the ENE with periods around 9 seconds, and the energy jumps to strong, around 405. But again, the wind is cross-onshore and choppy. It’s got power, but it’s not going to be pretty.
So, keep your expectations low. There’s one morning—Friday the 25th—that’s got a chance to be fun. Out at Sebastian Inlet-First Peak, it’s a beach/jetty setup, so with a little luck and a clean offshore, you might get a few. It’s not going to be epic, but it’s the best of a pretty poor run. Hang in there, because things might loosen up after this.
Stay salty.
