Twenty First Street (Miami Beach)

Twenty First Street (Miami Beach) is an urban Atlantic beach break over sand with clean water and a noticeable chop. The spot is best thought of as a place that can offer something to multiple boardsports, but conditions matter: surfing tends to be exposed and peaky, and it often becomes messy or closes out near the shore. For wind sports, winter and early spring provide the most supportive, most consistent wind angles for riding. For wind: the most favorable directions are generally from the NNE through SSE, aligning with winter frontal patterns. Typical winter conditions are described as moderate reliability, with a stated typical range around 12–25 knots. A late-spring pattern can include occasional afternoon sea-breeze influence, while summer is described as lower reliability. Kite sizes are commonly selected in a broad winter range, reflecting seasonal wind strength. For surfing: it’s described as an exposed beach break that works only when conditions line up well. Guidance points to low tide as the key window, with rides typically short and fast—often closing out as they reach the shore. The working swell direction is tied to north–northeast to east-northeast (reported as NE/E/ESE depending on source wording), with a stated working swell-height window roughly 0.5–1.5 meters. Larger swells can make paddling out difficult and the water can get messy. Safety is a priority at this spot. Reported hazards include rips, swimmers, obstacles/urban infrastructure elements such as rock groins/jetties and buoy lines, along with pollution concerns after heavy rain, sharks (seasonal reports), and seasonal jellyfish/Portuguese Man o’ War. Kitesurfing also has operational restrictions: riding is limited to designated zones and you must keep distance from swimmers and the shore. Ocean Rescue contacts are provided for local emergency response, and seasonal lifeguards may be present.
