The Lowdown
Alright folks, Rusty here. Let’s be straight with you about the next 16 days for South Beach. I’ve looked at the numbers, and I’m not gonna sugarcoat it – this is a flat spell, plain and simple. We’re looking at a long stretch of minimal to no surf, and honestly, there’s not a single day in this whole forecast window that’s worth paddling out for. The first real chance of anything rideable just isn’t showing up.
Starting off right now, the outlook is grim. For the first week, from Thursday the 30th of July through to Friday the 7th of August, we’re looking at tiny, weak waves. The swell heights are barely registering, most of the time sitting at just 0.3 ft to 2 ft. The periods are short, mostly 3 to 5 seconds, which is just wind chop. The combined energy is weak, sitting in the single digits to low 20s (4 to 28). It’s surfable only for a floating log, and even then, it’s a struggle. The winds are mostly cross-shore or onshore, which messes up any chance of a clean face. There’s a brief moment on Tuesday morning, the 4th of August, where the wind goes glassy, but the swell is still a pathetic 2 ft with a period of 4 seconds – it’s too small to do anything with.
Then we hit a real dead zone. From Saturday the 8th of August all the way through to Friday the 14th of August, the surf is essentially non-existent. The swell drops back to 0.3 ft most days, and the combined energy is in the gutter (3 to 18). The winds are a persistent cross-onshore, making it choppy and rubbish. There’s a slight bump on Monday the 10th and Tuesday the 11th of August, with the swell getting up to 2 ft from the SE, but again, the period is a short 4 seconds and the wind is onshore. It’s just not worth the effort.
So, the best wave on offer? There isn’t one. Nothing stands out. The only break in the mix is South Beach (Miami), a consistent beach/jetty break that’s sheltered from the swell. The water temp is sitting at 87°, which is about 2° above the norm for this time of year, so it’s a bit warmer than usual. But with no swell, that’s the only story. The poor conditions are a real drag, but for a spot like this in the middle of summer, a flat spell isn't that unusual. It’s a long wait. Keep your board in the car and your eyes on the horizon, but I wouldn’t hold your breath just yet.
Rusty.
