Right then, let’s have a look at what’s on the table for 21st Street (Miami) over the next couple of weeks.
Honestly, mate, it’s a bit of a grim stretch. The water’s a touch warmer than normal for the time of year at 87°, but that’s about the only highlight. We’re staring down the barrel of a flat spell with nothing worth paddling out for across the entire 16-day window.
Starting from this Sunday morning, the 5th of July, it’s all tiny, weak slop. Swell heights are hanging around 0.7 ft to a max of 3 ft, and the wave energy is practically non-existent – we’re looking at readings as low as 7 and never even cracking a hundred. The periods are short and fat, mostly 3 to 8 seconds, so there’s no push or power behind anything.
The wind is the real killer. It’s cross-shore or cross-onshore for almost the whole run, and those afternoon breezes are going to have it choppy and messy. There’s maybe a glimmer on Tuesday the 7th of July morning with a light breeze and clean conditions, but with that swell being just 0.7 ft and weak, it’s barely a ripple.
The swell direction tries to shuffle around a bit in the second week, with a sniff of NNE and NE direction around the 14th to 17th of July, but again, the height and energy just aren’t there to back it up. It’s all poor surf, every session, every day. If you’re desperate for a splash, you might find a knee-high wobble, but don’t expect a ride. The break itself is inconsistent, and this blank run is just the reality of the setup right now.
Nothing’s happening. No standouts, no hope spots. The forecast can always change, but for now, leave the board in the car.
