The Lowdown
Alright folks, Rusty here. Let's look at the Jupiter Inlet South Jetty outlook. Straight up, this is a lean run. The next week and a half is a tough watch. We've got days of tiny, weak, onshore junk that just isn't gonna give you a ride worth paddling for. The first solid window doesn't open until the 3rd of September, and even then, it's not going to be firing. The water temp is sitting at 86°, which is about average for this time of year.
The first real chance to get wet comes Thursday morning, the 3rd. The swell is small, around 1 ft from the ENE with a decent 13-second period, and we’ve got a light cross-offshore breeze from the SW. The combined energy is weak at 68, but it’s the cleanest we’ve seen. It’s surfable, but you’ll be scratching for waves.
The standout, and I mean the best on offer in this whole 16-day window, is Friday morning, the 4th. A true offshore wind from the West, which is the optimum for this jetty, will groom that 2 ft, 14-second E swell into something fun. The combined energy kicks up to a moderate 136, and the clean conditions will make the most of it. It’s not big, but it’s the pick of the bunch. Expect crowds for this one.
Saturday morning the 5th still has some clean surf with light cross-offshore wind, but the energy drops back. After that, we slide back into onshore winds and choppy conditions until the 7th.
Hold on, Monday afternoon the 7th gets interesting. The wind goes glassy, zero mph, with a 3 ft NE swell and a combined energy of 121 (moderate). That’s a rare window of absolute clean conditions. That 3 ft, NE swell will be perfect for the jetty. It's not the biggest, but glassy conditions at the jetty are a treat.
Tuesday the 8th looks decent again with clean offshore winds from the WSW and a solid 3 ft, 9-second NE swell. The energy holds at a moderate 125. This will be another solid session before it all fades.
So, the weekend of the 4th and 5th, plus the Monday the 7th and Tuesday the 8th, are your only real shots. The rest is a flat, choppy write-off. Keep your expectations low, but keep an eye on that Friday the 4th morning and that glassy Monday afternoon.
Rusty.
