The Lowdown
G'day, I'm Rusty. Let's be straight with you—this is a tough stretch for South Beach (Miami). The water is running a touch warmer than normal at 87°, about 2° above the long-term average for this time of year, so it's notably warm but not extreme.
Honestly, looking out over the next 16 days, there's nothing to get excited about. The whole forecast window is a write-off for decent surf. From Wednesday the 19th of August all the way through to Thursday the 3rd of September, every single day is labelled "poor surf conditions." The combined swell energy stays weak, rarely cracking 20 (3 to 43 range), with most days sitting below 20—that's barely a ripple. Swell heights are tiny, mostly 0.3ft to 3ft, with periods short and messy, often under 6 seconds. Winds are nearly always cross-onshore or cross, keeping things choppy and blown out. You'll get a few glassy mornings around the 30th of August and 31st of August, but with next to no swell, it's flat calm, not surfable.
There are no standout days or breaks here. The only break in the guide is South Beach (Miami)—a sheltered beach/jetty setup that's consistent but rarely sees quality. With the swell direction mostly from the east or northeast, it's not lining up with the optimum NNE direction either. This is a blank run for surfers. If you're into kite surfing, the choppy, onshore afternoons with moderate breeze might offer some fun, but for paddle surfing, leave the board at home.
Hang in there—forecasts can change, but for now, it's a long wait.
