The Lowdown
Alright crew, Rusty here. Let’s call it like it is – this 16-day outlook for Jupiter Inlet South Jetty is a flat spell. The first any surf worth mentioning shows up on Wednesday morning, July 15th, and even then it’s a stretch. From now until then, don’t bother.
Water temp is a warm 86°, which is right on the money for this time of year.
The whole run is tiny swells, mostly from the NE and ENE, with heights barely scraping 3 ft and periods mostly under 8 seconds. That’s short-period, wind-driven junk. The combined energy is weak, mostly in the single digits or low double digits (13, 29, 30), so there’s no power behind it.
Wednesday morning, July 15th, is your first chance. We’ve got a tiny 2 ft NE swell, but the wind is glassy – dead calm. If you’ve got a soft top and just want to sit in clean, flat water, go for it. It’s not surf, but it’s a session.
Thursday morning, July 16th, is similar: 1 ft NE swell, glassy, with a light offshore from the WNW. Clean, but barely a ripple.
Friday morning, July 17th, another glassy morning with a tiny 0.7 ft ENE swell. Same story: clean, not enough to ride.
The rest of the period is a mix of light offshore and cross-onshore winds, but the swell never builds. Afternoons get chopped up by sea breezes, and the few clean mornings have nothing to work with. The combined energy tops out at 35 (July 23rd afternoon), but that’s still weak, with a 0.7 ft ESE swell and a 5-second period – messy, short-period mush.
No standouts. No big swell, no long-period groundswell, no power. This is a blank run, and it’s normal for summer here, but it still stings.
Keep your eyes on the charts, things can turn. For now, maybe take the week off.
Rusty.
