The Lowdown
Alright, Rusty here. Let’s talk about what’s shaping up at South Beach (Miami) over the next couple of weeks.
Honestly, it’s a tough stretch. The whole 16-day window is one long, flat gap with no real surf to get excited about. The water is a touch warmer than normal at 87°, but that doesn’t help the waves. We’ve got tiny, weak swells coming from the NNE mostly, but the energy is way too low – mostly between 6 and 52 (moderate wave energy) – and the periods are short, under 8 seconds, meaning no power at all. The wind is almost always cross-on or onshore from the east or southeast, keeping things choppy and messy. For the better part of the first week, from Thursday the 10th right through to Sunday the 20th, it’s flat and blown out.
There is a little glimmer late in the run. Starting around Monday the 21st, we get a switch. The wind turns cross-offshore from the NNW, and the swell picks up a touch to 2ft from the NNE, with a period up to 8 seconds. Combined energy climbs to 38 (moderate wave energy) and the surf is described as clean. It’s small, but at least it’s clean for a morning session. Then on Wednesday the 23rd, we see the best of the bunch: offshore wind from the WNW, 16 mph, with a 3ft NNE swell, period 7 seconds, and energy ramping up to 105 (strong wave energy). It’s still rated as poor surf conditions, but with moderate offshore wind cleaning it up, that’s the standout moment on offer for the whole outlook. The afternoon of the 23rd keeps that clean, cross-off feel too. By Thursday the 24th, the swell gets a little bigger – up to 5ft – but the wind turns cross-on again, so it gets choppy.
If you’re a beginner, the early part is flat and the later part sees waves up to 5ft, which is fine for learning if the wind isn’t ripping. For the crew on bigger boards, the clean windows on the 21st and 23rd are worth a paddle. The week-two stuff is promising but less certain. Nothing here for experts – the max swell stays under 5ft.
Given the long flat spell and the day-after-day of poor conditions, it’s one of those periods where the beach looks better for a flat-water session or maybe a kite setup if the wind really pumps. But for a surfboard, you’ve got to wait until the very end of the run.
Stay patient.
Rusty.
