The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ in our local waters.
Right off the bat, I gotta be straight with you – the next week and a half is a bit of a grind. There’s nothing really worth paddling out for from now through the 22nd of August. We’re talking tiny ankle-biters and onshore junk, a real flat spell. You’d be better off waxing your board for later.
We finally see a glimmer of hope on Sunday the 23rd of August. Indian River (Northside) will see some small, clean waves. It’s not going to be epic, but that cross-off wind will keep the surface tidy. The combined swell energy is weak (108), with a 3ft swell from the S. It’s surfable, but you won’t be telling stories about it.
The real standout, the one that’s got my heart racing a little, is Monday the 31st of August. Now we’re talkin’. The morning session at Indian River (Northside) is where you want to be. We’ve got a solid 6ft swell rolling in from the E, with a light offshore wind making it glassy clean. The combined energy is a solid moderate push (248). This is the pick of the whole run. The water temp is about average for this time of year, so a spring suit will do you fine. Just be warned, the afternoon chops it up with a side shore breeze.
After that, the first couple days of September look pretty average again, so make the most of that Monday morning.
Rusty.
