The Lowdown

Hey folks, Rusty here. Let’s be straight with you—this outlook for Jupiter Inlet South Jetty is a tough one. We’re looking at a solid 16-day window, but the first week and a half is basically a write-off. There’s just no surf to get excited about. From Monday afternoon, July 27th, all the way through to the start of August, we’ve got tiny, weak swell—mostly 0.3ft to 1.0ft—with periods barely cracking 8 to 10 seconds. The combined wave energy is basically a whisper, sitting between 5 and 14 (weak energy). Winds are mostly offshore or cross-offshore, so it’s clean, but you’re looking at flat, wobbly nothing. A few mornings have that glassy, inviting look, but there’s no push behind it. The water temp is sitting at 86°F with a 1°F anomaly, so it’s about average for this time of year.

We slog through a few days of risk t-storms and onshore junk toward the end of the first week and into the second. By Thursday, August 6th, the swell tries to bump up to 2ft, but it’s a short-period 4-second windswell from the ESE, and the wind is onshore, making it choppy and messy. The energy climbs to 31 (weak), but still, it’s poor surf conditions. That pattern of poor quality holds through the weekend.

Now, here’s the one glimmer. On Monday, August 10th, we get a moment of calm. The morning goes glassy—wind is dead calm from the WSW, 0 mph. The swell is 2ft from the SE, period 4 seconds, and energy is 31 (weak). It’s small and sloppy, but glassy conditions mean it’s the cleanest you’ll see all window. That’s the best on offer, and it’s still a far cry from good. The real standout? Tuesday, August 11th morning. The swell picks up to 3ft from the ESE, period 5 seconds, and the wind is a light offshore from the SW at 6 mph. Energy jumps to 49 (still weak). For this break, that’s the pick of the litter—a clean, small wave for the advanced crew looking to get wet. But honestly, it’s not much. If you’re a beginner, the swell never gets over 5ft, so you’re not in danger, but there’s almost nothing to ride.

Given the constant poor surf conditions and the lack of any real swell, this setup is more interesting for kite surfing than paddle surfing on most days, especially when the wind is cross-on or onshore.

Signing off, Rusty.
