The Lowdown
Alright folks, it’s Rusty here. Gotta be straight with ya – the 16-day window for South Beach (Miami) is a tough one. We’re looking at a long stretch of flat, weak conditions that just won’t give us a proper wave. The whole forecast period is basically a write-off for paddle surfing.
Starting Monday, September 7th, we’ve got a tiny 0.3ft swell from the NE with a short period – the combined energy is a measly 4 to 6 (weak energy). It’s labelled “poor surf conditions” straight through. The wind is cross-offshore or glassy on Tuesday morning, which would be perfect for clean waves, but there’s simply no swell to work with. The water temp is about average for this time of year, so nothing unusual there.
We move through the next few days, and it’s the same story. Wednesday the 9th sees a bump to 1ft and 3ft from the NNE, but with a period of only 8 to 9 seconds and onshore wind, the energy only climbs to 48 and 89 (still weak). Still poor. Thursday and Friday are just more of the same – tiny, weak, onshore slop. The combined energy barely cracks double digits, staying in the 4 to 51 range all week.
The weekend of the 12th and 13th is flat. 0.3ft to 0.7ft. No energy. The following week is just as grim. By the 20th of September, we get a tiny 1ft to 2ft NNE swell with a bit of a cross-offshore breeze, but the energy is only 20 to 29 (weak). The period is short, and it’s still “poor surf conditions.” This spot is a sheltered beach/jetty, so it needs a proper push from the NNE to work, and it just isn’t coming.
Honestly, there are no good surf options here. Not a single day in the 16 days offers anything worth paddling out for. The setup looks more interesting for kite surfing than paddle surfing on the few days with a breeze. The area is going through a blank run, and it’s a common thing for this stretch of coast. Forecasts can change, but as it stands, leave your board at home.
Rusty.
