The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook for South Beach (Miami) is a tough one. Over the next 16 days, from July 17 through to August 1, there’s just nothing to get excited about. Every single session shows poor surf conditions, with the wave comment saying exactly that. The swell is tiny, mostly under 2 ft, and the combined energy never gets past a weak 82 (that’s the highest we see on July 30 afternoon). The water is warm – about 87° on the 17th, which is a touch warmer than normal for this time of year – but that’s the only bright spot.
South Beach is a sheltered beach/jetty setup, and it’s consistent when conditions are right, but the optimum swell comes from the north-northeast. Unfortunately, the entire forecast window is dominated by south, southeast, and east winds and swells, which just don’t line up. The wind is mostly cross-on or cross, and often moderate to fresh, so the surface is choppy or lumpy. For a beginner-friendly spot like this, it’s a real bummer.
There are no standouts, no hidden gems, no surfable days. It’s a flat run, and for this area, that’s not unusual when the swell direction is wrong. Forecasts can change, but as it stands, you’d be better off saving the gas and waiting for a proper NNE pulse. Keep an eye on the long-range – sometimes a late-season shift can surprise us, but for now, it’s a no-go.
Rusty.
