The Lowdown
Alright, this is Rusty. Let’s talk about your local surf.
Honestly, the next couple of weeks look pretty flat. We’ve got a long stretch ahead with hardly any rideable swell. For the first ten days or so, from Tuesday the 14th through to around Friday the 24th, it’s a write-off with tiny waves and poor conditions. There’s a bit of a gap here where nothing is worth paddling out for. It’s not until Saturday the 25th of July that we see a tiny flicker of life, and even that is a very small window.
If you’re really keen and want to get wet, your only real look is 21st Street (Miami) on the morning of Saturday the 25th. We’ve got a small swell coming in from the Northeast at about 1 ft with a long period of 11 seconds. The combined wave energy is only a weak 33, so it’s not powerful, but that longer period will give the waves a little more shape. The wind is a cross-onshore from the Southeast at 12 mph, so it’ll be a bit bumpy and choppy, but the water temperature is sitting about a touch warmer than normal for this time of year.
This spot is inconsistent, so catching a set will take patience. The swell is small, so it’s fine for beginners. You can expect crowds here often.
Honestly, for most of this period, the surf quality is just poor. The wind is always coming from the side or onshore, which messes up any tiny bump. It’s a real bummer, but it tends not to stay poor for long in these parts. Forecasts can change.
Stay patient, Rusty.
