The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for South Beach (Miami) is a tough one. We’re looking at a long stretch with barely a ripple, so don’t get your hopes up for anything worth paddling out for.
The whole 16-day run is dominated by tiny, weak swell. The combined energy barely ever gets above 30 (25-26 is the highest we see), which is just weak, anemic stuff. We’re talking knee-high dribble at best. The only swell that shows up is from the SE and SSE, but it’s short-period slop (4 seconds) that won’t wrap in here like it should, especially with this break being sheltered and needing something from the NNE to really work. Basically, the swell direction is all wrong.
We start on Friday the 14th of August with a cross-onshore breeze and 1ft of junk. Saturday the 15th is more of the same – 2ft with a cross-onshore wind. It’s just poor, choppy conditions. Then from Sunday the 16th onward, it flatlines. For days on end, we’ve got 0.3ft surf. Even though we get a few glassy mornings on Monday the 17th and Tuesday the 18th with the wind going light or variable, there’s simply no wave to ride. The water temp is about average for this time of year, for what that’s worth.
There’s nothing here to highlight as a standout. That 2ft on Saturday the 15th might look like something, but with the cross-onshore wind and weak energy (26), it’s just a messy, tiny dribble. If the wind were offshore, it’d be a different story for the micro-swell, but it’s not. For anyone looking to paddle, this is a write-off.
The only thing that’s even semi-consistent here is the lack of surf. It’s a blank run. Given the setup, if you *had* to be on the water, this looks more interesting for a kite than a paddleboard.
Stay patient, and check back – things can change.
Rusty.
