The Lowdown
G’day, this is Rusty. Look, I’m not gonna sugarcoat it—the next 16 days at Dunes Hotel (Miami) are a total flat-out bust. The spot is sheltered from the swell, and the only waves we’re seeing are tiny, weak wind-slop running 0.3ft to 3ft, with combined swell energy barely reaching 38 (very weak). Water temp is about 87°F, with a 1°F anomaly—pretty average for the season.
The first half-decent chance comes Saturday morning, August 15th, with a 3ft swell from the southeast at a period of just 5 seconds—that’s short-period, wind-driven junk. Winds are cross-onshore at 16 mph, so it’s gonna be choppy and messy. Not worth the drive.
After that, it’s a long, dry spell. The rest of August and into late August stays flat—tiny 0.3ft to 1ft waves, mostly onshore or cross-onshore, with periods barely hitting 10 seconds. The only nice moments are a couple of glassy mornings on Monday, August 17th, and Tuesday, August 18th, but with 0.3ft swell, it’s just a flat, oily lake. No rideable surf.
For kite surfers, there’s a bit of wind—like Saturday afternoon, August 15th, with 16 mph cross-onshore, and Wednesday afternoon, August 19th, with 16 mph cross-onshore—but for paddle surfing, it’s a total write-off. This spot’s sheltered nature is really letting us down. Forecasts can change, but right now, I’d say leave the boards at home.
Rusty.
