The Lowdown
Alright, Rusty here again for the imperial crew. Dunes Hotel (Miami) is a sheltered beginner spot, and over the next 16 days, we are scraping the barrel. The swell is tiny, the wind is often messy, and this stretch of coast just isn’t giving. The water is running about 87° and a bit warmer than usual for this time of year. Don't plan your session around it yet.
We kick off Thursday afternoon, August 20th, with a pathetic 1ft swell from the south at a piddly 3-second period. A storm risk and 12 mph crosswind makes it a write-off. Friday the 21st is worse—0.3ft of NE nothing. This poor surf carries on for days. Saturday the 22nd? 0.3ft again with cross-onshore breeze. Monday the 24th slaps us with 2ft of onshore slop. We are in the doldrums. The combined energy readings are mostly single-digit figures, like 6 and 4, showing zero power.
Way down the line, we have a slight shift. On Monday, August 31st, a glassy morning with 3 mph wind from the SW cleans up a 1ft ENE swell with 14 energy. It’s tiny, but the surface will be like glass. The standout, believe it or not, is Friday, September 4th. The morning is glassy with a 1ft NNE swell at an 8-second period and the energy jumps to 43. That’s still a small wave, but it has some grunt compared to everything else. The afternoon bumps up to 2ft with 53 energy but the wind turns onshore at 12 mph and chops it up. That is the absolute best we get after a gap of over a week of nothing. For riding a surfboard, it's a long dry spell. For a kite, there might be something in the breezy afternoons.
Rusty, signing off.
