The Lowdown
Alright gang, Rusty here, and I’ve got the outlook for your stretch of sand. It’s a grim picture, plain and simple.
We’re staring down a solid 16-day spell with practically nothing on offer. From now all the way through the end of July and into the first few days of August, the wave energy is just pathetic.
The only spot that even pops up is Jupiter Inlet South Jetty. Water temp is 86°, which is about what you’d expect for the season, nothing out of the ordinary.
For Tuesday the 21st, you’ve got a tiny 3ft swell from the SSE, but it’s paired with a shocking 5-second period and a cross-on wind from the SSE at 15 mph. The combined energy is a lousy 33. It’s just messy, choppy junk. That story repeats through Wednesday, Thursday, and Friday. Swell heights hover around 1ft to 2ft with zero punch, and the wind is either cross-on or onshore the whole time.
Saturday the 26th morning has a clean look with a 1ft swell from the ENE and a light offshore wind from the west at 6 mph. But the period is only 8 seconds and the energy is a weak 20. It’s clean water, but you’d be fighting for scraps.
From Sunday the 27th through to Wednesday the 5th of August, the bottom falls out. The swell drops to 0.7ft or 1ft. There are some glassy or clean moments on the 28th and 29th, but trust me, you can’t ride what isn’t there. The energy numbers are in the single digits or low teens—dead flat. Tuesday afternoon the 28th has glassy conditions, but on a 0.7ft swell? You’d just be bobbing around.
Even into August 4th, it’s 2ft from the SSE with a 4-second period and a 9 mph onshore wind. More suited for a kite session than a paddle.
For a break that’s usually fairly consistent, this is a big, ugly donut. Don’t hold your breath. If you see a ripple, consider yourself lucky.
