The Lowdown
Alright, Rusty here. Let's get real about what’s on the table for the next couple of weeks.
Honestly, it’s a tough stretch for South Beach (Miami). This spot is a sheltered beach and jetty setup, and it’s consistently getting hit with onshore to cross-onshore winds from the east and southeast. The first week is a write-off. From Saturday the 29th of August right through the following week, we’re looking at tiny swells, mostly around 0.3 ft to 3 ft, with short, weak periods of 3 to 4 seconds. The combined swell energy is laughably low, peaking at just 39 on the scale (moderate energy), but it's all wind swell. Every session is flagged as "poor surf conditions." Don’t even bother paddling out until we get past the first week—it’s nothing but choppy, weak lines.
There’s a short glimmer on Sunday morning, September 6th, when the wind goes glassy calm from the SSE. But the swell is a pathetic 0.3 ft with a 7-second period. Combined energy is 2. That’s basically a lake. Not worth the wax. The same happens again on Monday, September 7th morning with another glassy window, but again, almost no swell. The water temperature anomaly is about average for this time of year, so at least you won’t freeze while you’re floating around doing nothing.
The second week doesn’t get much better. By Tuesday, September 8th morning, we finally get a light cross-offshore wind from the WNW, and the swell period stretches to 13 seconds—that’s a long-period groundswell. But the height is only 0.3 ft and the combined energy is a measly 8. It’s clean, but there’s nothing to ride. For the rest of the week and into the next weekend, the pattern stays the same: tiny, inconsistent swells and mostly onshore winds. There is absolutely no standout window here. This is a long, flat spell for the neighborhood. If you’re desperate for a wave, you’re better off checking the jetty on one of the glassy mornings in early September, but keep expectations in the gutter.
