The Lowdown
Rusty here. Let's break down what's ahead on your stretch.
Honestly, the next 16 days are a pretty quiet affair. We're looking at a big, long gap of nothing much before a single window of opportunity shows up. For the first 11 days, from Sunday, September 13th, right through to Wednesday, September 23rd, it's all tiny surf and poor conditions. Swell heights are mostly 0.3 ft or less, with combined energy in the single digits or low tens – real weak stuff. Wind is messy, mostly cross or onshore, so even that tiny bump gets torn up.
The only real chance to get wet comes on Thursday, September 24th. That morning, we see a NNE swell at 3 ft with a 10-second period and moderate energy (117). The wind is a light cross-off from the NNW, so it'll be clean. But the afternoon is the real standout. The wind goes glassy, the swell holds at 3 ft from the NNE, and the combined energy bumps up to 135. For a sheltered spot like South Beach (Miami), that's about as good as it gets. It's a beach and jetty break and it's consistent, so you can expect some fun little waves. Water temp is about average for this time of year.
After that, Friday the 25th onward, the swell fades and the wind gets messy again. So if you're looking for a paddle, your one and only window is that Thursday. Make it count.
Rusty.
