The Lowdown
Hey folks, Rusty here. Let’s be straight with you – the next 16 days out at South Beach (Miami) are a real bummer. We’ve got a long stretch of nothing worthwhile, stretching from now all the way through to early August. The swell is tiny, the wind is mostly onshore or cross-shore, and the energy is weak. The water temperature is sitting right around 87°, which is a couple of degrees warmer than usual for this time of year – so it’s a touch toastier than normal, but nothing too wild.
The first real chance of anything at all? Not until around the 28th of July. Tuesday morning, the wind swings to a light cross-offshore from the SSW, and the water cleans up. The swell is a pathetic 2 ft out of the south, with a period of only 4 seconds – that’s pure wind chop, not groundswell. The combined energy is a measly 12 (weak). It’s not good, but it’s the cleanest we’ll see for a while.
Honestly, if you’re after a paddle, there’s nothing here. The setup is a sheltered beach/jetty, and the swell never gets above 3 ft, with such short periods that waves are just crumbly and weak. If you’re a kiter, maybe you could make something of the cross-shore winds on the 20th and 21st, but for a surfer? Forget it. The whole 16-day window is a write-off – a blank run that’s pretty normal for this area in summer.
The best on offer is the early morning of the 28th, but even that’s a stretch. The wind is clean, but the swell is sad. I’d wait for a proper system to roll through. Forecasts can change, but right now, South Beach is a no-go.
Rusty.
