The Lowdown
Alright, this is Rusty, and I gotta be straight with you. We’ve got a 16-day window here, but honestly, it’s looking like a long, quiet stretch for the Jupiter Inlet South Jetty.
Right off the bat, the first day, Monday August 3rd, is a total write-off. We’re looking at tiny 0.6ft easterly windswell with a short 8-second period, and the combined energy is a pathetic 14. It’s basically a lake out there. Tuesday the 4th starts with a glassy 0.6ft, but that’s just flat. The water is sitting at 85°, which is about what you’d expect for the time of year, so no surprises there.
We roll through the whole first week and into the second with the same story. The swell doesn’t crack 3ft until Thursday the 6th, and even then, it’s short-period, onshore junk. By Friday the 7th, the swell pushes up to 5ft from the east, with a combined energy of 147 (moderate), but the wind is howling onshore at 15 mph. That’s messy, blown-out conditions, not worth a paddle. The period is a weak 6 seconds, so it’s just wind slop. For a more advanced spot like this, it’s a pass.
There is a gap of several days with no real hope. The swell hangs around the 2ft to 3ft mark for the rest of the week, with onshore or cross-onshore winds, and short periods. It’s frustrating.
The only glimmer of something *less* terrible comes on the very last day, Tuesday August 18th. The morning shows a tiny 0.6ft from the ESE, but with a 9-second period and a light cross-onshore breeze. The combined energy is a measly 11, but the period is the longest we’ve seen. It’s barely a ripple, but it’s the cleanest ripple in a sea of bad options. Don’t get your hopes up.
Honestly, for the whole 16 days, there is nothing that even sniffs at a standout. The wind is almost always onshore or cross-onshore, killing any chance of a clean face. The swell is consistently small and weak. Given the setup here is a beach and jetty, the onshore winds just make it look like a better day for a kite than a surfboard.
This is a tough one. A blank run like this is pretty normal for the area in this kind of pattern. Keep the wetsuit handy, but don't hold your breath.
Rusty.
