Alright, Rusty here. Let’s be straight with you – looking at the next 16 days for the Jupiter Inlet South Jetty, it’s gonna be a long, quiet stretch. The forecast is basically a flat spell with no real surf to get excited about. From Sunday July 12th all the way through to Monday July 27th, the model keeps spitting out tiny, weak waves. That’s a solid 16-day gap where nothing really stands out as worthwhile.
The water temperature is sitting at 86°, which is about 1° warmer than usual for this time of year – nothing crazy, just a little on the warm side for a summer paddle.
The overall wave energy is a pretty sad story. Most days the combined energy is down in the single digits or low teens (like 9, 10, 17, 29 on the highest end), which is what we call “weak” energy. The swell heights barely break 2 ft, and the periods are short, mostly between 3 and 9 seconds. That’s not groundswell, that’s just wind slop.
There are a few mornings where it goes glassy or gets a light cross-offshore breeze from the NW or WNW – like on Friday the 17th and Saturday the 18th of July, or Sunday the 19th – but the swell is so small (0.7 ft to 1 ft) that it’s barely a ripple. The swell direction is mostly from the NE and ESE, which is fine for the jetty, but without any size, it’s just a lake.
Even the “best” options on offer are a total non-event. For example, Monday morning July 13th is glassy with a 0.3 ft NE swell, or Thursday morning July 16th is also glassy with 1 ft from the NE. But honestly, those are just flat days with a clean surface. There is no punch, no power, no decent wave to ride.
This is a break that’s fairly consistent normally, but this run is a blank one. The only thing worth noting is that if you’re a kite surfer, the strong onshore winds (ESE up to 16 mph later in the week) and the small, choppy surf might be more your speed than paddle surfing. For the rest of us, it’s a board-waxing and sunset-watching kind of forecast.
Rusty.
