The Lowdown
Alright, it’s Rusty here. Let’s break down what’s happening for the next couple of weeks.
To be honest, we’re lookin’ at a pretty flat run. The first proper chance at a wave doesn’t roll in until Wednesday, July 22nd, and even then, it’s nothin’ to write home about.
The water is about 76°, which is a touch warmer than usual for this time of year. Feels nice, but it won’t put a bend in the wave.
From Friday the 17th all the way through Tuesday the 21st, it’s pretty much dead. Tiny, weak swell with the combined energy barely hittin’ 20-30 (weak). The wind is all over the place, mostly cross or onshore, and you’d be fightin’ chop if you even tried to paddle out. Don’t bother.
The first real window is Wednesday morning, July 22nd at Indian River (Southside). We’ve got a bit of a bump: about 3ft from the SSE, with a 9-second period. The combined energy hits 138 (moderate), which is the best we’ll see. The wind is clean offshore from the W, which is a big plus. It’s surfable, but it’s an advanced spot, and with that size, it’s not for the beginners. This is a beach/jetty setup, so it’ll be a bit of an effort. The best of the week, but it’s a low bar.
After that, it’s back to the small stuff. Thursday the 23rd to the end of the month, the swell drops to around 1-2ft. There are a couple of glassy moments, like Thursday afternoon the 23rd and Saturday morning the 25th, but the energy is just too weak to get a proper ride.
The first week of August is more of the same – tiny, weak, and messy. The combined energy numbers stay low, mostly under 100 (weak), and the wind is mostly cross or onshore. Tuesday morning the 28th has a little bit of swell from the S, but it’s short period and the wind is cross-off, so it’s just a mediocre window.
If you’re a kite surfer, the windier days might look a bit more fun than a paddle board. But for a regular surfer, this is a tough stretch. The break is fairly consistent around here though, so it won’t stay this bad for long. Keep an eye on the forecast.
Rusty, signing off.
