21st Street (Miami) Surf Forecast and Surf Report

Alright, this is Rusty. Let me tell you what's happenin' here. We're gonna look at the 16-day window for the Miami area, and I gotta be straight with you – it's a tough stretch. There's a long gap of flatness and poor conditions right off the bat.

From Saturday the 29th of August, all the way through to the end of the first week of September, there's just nothing to get excited about. We're looking at tiny, weak swell – mostly around 0.7ft to 2ft from the east and southeast, with periods that are short and choppy. That combined energy is just pitiful, barely cracking 44 (moderate wave energy) at best, and mostly sitting in the weak double digits. The wind is a mess, too – mostly onshore or cross-onshore, making it a choppy, lumpy mess. Really, it's a write-off for paddle surfing. The water is a touch warmer than normal at 87°F, about 2°F above average, but that's the only thing going for it.

The first glimmer of hope comes on Thursday the 3rd of September. The swell height bumps up to 4ft from the ESE, with the combined energy hitting 112 (moderate wave energy). But the wind is still a problem – cross-onshore and gusty, with a risk of thunderstorms. It's still not a recommendation, just less terrible.

You see a few days with some period in the swell, like on the 1st of September when we get a 12-second period, but the swell height is only 0.7ft. It's a tease.

We go through a long, flat spell until we get to the 10th of September. That Thursday morning, the wind goes glassy out of the southwest, and the swell is 1ft from the NE with a 10-second period. The combined energy is 29 (weak wave energy). It's clean, but the wave is tiny. Same story on the 12th of September, Saturday morning, glassy again, but we're looking at a 0.7ft swell. The 13th of September, Sunday morning, we get another glassy window with a 0.7ft swell from the east. It's clean, but it's a knee-high dribble at best. The conditions are perfect for a longboard or a sup, but there's no power behind it.

To be honest, with the persistent onshore flow and lack of substantial swell, and the beach-break setup, this whole period looks more interesting for kite surfing than paddle surfing. The wind is consistent, even if the swell isn't.

There are no standout surf days in this 16-day window. The forecast for the second week looks just as flat as the first. I'd say keep the board in the car, but don't hold your breath. The forecasts can change, but right now, it's a real bummer.

Rusty.
