The Lowdown
Alright, let’s get real. The surf scene is pretty much on hold for the next stretch. Water’s a balmy 86°, which is a touch warmer than usual, but you’re gonna be sitting around waiting more than anything.
It starts off flat and messy Wednesday the 9th. We got a knee-high wave at 3ft, but the period is short and the wind is all cross-on, making it a total choppy mess. The energy is weak, in the 125 range. Thursday the 10th is the same story, slipping to 3ft and still junky. By Friday the 11th, it’s barely 2ft and the period has dropped to 6 seconds. It’s not surfable, just bump. The whole weekend and into the following week is completely flat, with waves below 2ft and periods of 4-5 seconds. You’d be better off finding a lake.
There is a tiny glimmer late in the game, around Monday the 21st. The swell bumps back up to 3ft from the NNE, with the energy back up to a weak-to-moderate 100. It’s still onshore, so it will be lumpy, but the period is at least a more reasonable 8 seconds. Tuesday through Thursday the 23rd and 24th keeps that 3ft of NE swell, but it’s cross-on and blows a bit harder. It’s not good, but it’s the only game in town.
The only break on the map is Jupiter Inlet South Jetty, and this is an advanced zone. It’s the right direction for the swell, but the size and quality are just not there. The wind is gonna be your biggest enemy, keeping anything from getting any real shape.
Honestly, for most of this period, you’re gonna be looking at a kite surfer’s paradise, not a surfer’s. It’s a long, blank stretch of about 10 to 12 days before that weak pulse of energy arrives. It’s promising, but I wouldn't be marking the calendar. Forecasts change, but this one’s looking pretty locked in. Keep the board in the car, but maybe bring a book.
