The Lowdown
Alright, this is Rusty. Gotta level with you, the next couple of weeks are going to be a real test of patience around here. We’re looking at a long, drawn-out spell of tiny, weak surf that’s barely worth a paddle. There’s nothing on offer from the start through most of the second week.
For the first nine days or so, from Wednesday the 2nd through to Monday the 14th of September, it’s just a flat spell. We’re talking ankle-snappers at best, with combined swell energy struggling to even crack triple digits most days—sitting at a weak 83 (moderate energy) at the absolute best. The wind does go clean and glassy on a couple of afternoons, like Friday the 4th with a dead calm sea, but with waves only 1 ft from the SSE, you’d be floating. The swell direction is mostly way off the optimum and the period is short. It’s just not gonna happen.
We finally get a little pulse of life toward the end of the window. Tuesday the 15th shows some hope with a small NE windswell starting to show, and it hits a mark on Wednesday the 16th. That Wednesday morning looks like the pick of the entire forecast. Indian River (Southside) should see a clean 4 ft wave from the ENE under a light offshore breeze. The combined energy jumps to 266 (moderate energy), which is the biggest number we’ve seen by a long shot. It’s not massive, but after so long with nothing, that’s a standout. Thursday the 17th keeps the clean trend going with a 6 ft swell from the E under offshore winds, though the period is a short 6 seconds, so it’ll be a bit lumpy and crumbly.
So here’s the deal: the wait is brutal, but that Wednesday morning, September 16th, is worth flagging on your calendar. It’s the best we’ve got. Keep the faith, and your board waxed. Rusty.
