The Lowdown

Alright, let’s get this straight. The next couple of weeks are about as flat as a pancake around here. We’re looking at a long stretch of poor surf, with the first real glimmer of anything surfable showing up around the 19th. That’s a solid week and a half of waiting, so if you’re itching for a wave, you might want to find something else to do for now.

The energy in the water is just weak. Early on, we’re looking at combined energies in the 60s – that’s just a pulse, not a swell. It’s tiny stuff, knee-high at best, and with the wind mostly cross or cross-on, it’s going to be a messy mess. There are a few glassy moments, like the morning of the 11th, but the swell is a pathetic 1ft at 7 seconds. It’s not worth the paddle.

The gap is long. From now until the 19th, there is nothing that gets blood moving. The 15th has a bit of a pulse, but the period is a woeful 4 seconds, so it’s just wind chop. The 19th is when things finally start to change. We see a proper groundswell trying to show up, with a period jumping to 13 seconds. It’s still small, only 1ft in the morning, but the energy climbs into the 60s. The wind is cross-offshore, which is a good sign. That afternoon is glassy, and the swell is holding at 1ft with a 13-second period and energy up to 67.

That’s your first real window. It’s not big, but it’s clean and lined up. Then the 20th morning looks even better. We’ve got a 2ft east swell with an 11-second period and the energy jumps to 96. With that cross-offshore wind, Sebastian Inlet-Third Peak (Florida) should have some clean little peelers. It’s a beach/jetty setup, so long-period swell can be a bit straight, but the jetty can focus it. This is your standout. It’s not a day for the big boys, but for a log or a fish, it’ll be fun. There will be some crowds likely, it’s a consistent spot, but the clean conditions will be worth it.

The morning of the 21st is a bit of a letdown, with the energy dropping back to the 40s, but the afternoon bounces back with a 2ft swell and energy at 73. Another glassy one. That’s your second option.

After that, it’s back to junky onshore wind and small, weak swell. The 22nd and 23rd are write-offs. The energy is in the teens and twenties, and the wind is onshore. Forget it.

So, to sum it up: the first 10 days are a total blank. The standout is the morning of the 20th, with clean 2ft waves and decent energy. The afternoon of the 19th and 21st are also worth a look. The water temp is about average for this time of year, so no surprises there. It’s a test of patience, but there are a couple of fun windows if you’re keen.

Rusty.
