The Lowdown
Alright, Rusty here, and I've gotta be straight with you. Lookin' at this stretch for South Beach (Miami), I'm calling it like I see it: this is a flat spell. A real bummer.
We're talkin' a solid 16-day window here, and the honest truth is, there's nothin' to get excited about. The whole run is a gap. Not a single day on offer has anything worth paddling out for. The combined swell energy never cracks even a weak 100 (it's all between 1 and 26), and the wave heights are tiny – mostly flirting with 0.7 ft to 2 ft. That's ankle-snappers and knee-high slop, at best.
The wind is mostly cross-onshore or onshore, keeping things choppy and messy. Even when we get a light breeze, the swell just isn't there. There are a couple of moments on August 28th and September 2nd where the period bumps up to 12 seconds, hinting at some long-range energy, but the swell heights are still below 0.7 ft. It's all tease, no payoff. The water is a warm 87°F though, which is a touch warmer than normal for this time of year, so at least you won't be cold while you're sitting on the beach wishing for a wave.
This kind of blank run is more normal for the area, so don't be too surprised. It’s a sheltered spot, and when the juice isn't flowing, it's just flat. For a break like South Beach, you need a proper eastern or northeasterly push to get any life in it, and we just don't have that.
Stick to the paddleboard or find a pool. There's just no surf to be had here. Rusty out.
