The Lowdown
Alright, I’ll level with you—this is a rough one. The whole 16-day window from now through to mid-August is looking pretty flat for the Jupiter Inlet South Jetty. There’s just no swell to speak of. The biggest wave height we see is a paltry 3 ft on the morning of Monday, August 3rd, and even that’s coming from the SE with a short period of 4 seconds, which is barely a ripple. The combined energy of all swells directed here rarely cracks 30 (weak energy), with most days sitting in the single digits or low teens. That’s about as weak as it gets.
The weather throws in a few chances for offshore winds—like on the morning of Wednesday, July 29th, with a clean 12 mph offshore from the W—but with zero swell, it’s just a glassy, empty ocean. The water temperature is sitting at 86°F, which is about 1°F above normal for this time of year, so it’s not unusual—just warm.
Honestly, there’s no standout day here. Not one. The first few days of the window are completely flat, and the tiny bumps that show up later in the first week and into the second are too small and short-period to surf. The break is fairly consistent on paper, but when the swell is this absent, it’s just a waiting game. For a spot like this, a blank run is more normal than you’d hope. Expect at least a 10-day stretch with no real surf, and then nothing promising even after that.
If you’re desperate, kite surfers might find something in the onshore breeze on the afternoon of Saturday, August 1st, when the wind shifts SE at 6 mph and the water gets a slight bump, but for paddle surfing? Leave the board at home.
