The Lowdown
Hey folks, Rusty here. Let's talk about the next couple of weeks at Jupiter Inlet South Jetty.
We’re looking at a real dry spell to kick things off. For the first twelve days or so, the ocean is mostly flat or just full of tiny, useless waves. The swell is barely 0.3m to 0.7ft most days, with short, weak periods. The combined swell energy is pitiful, barely hitting double digits for a long stretch. Even when the wind is clean, like on Tuesday morning with a solid offshore breeze, there’s just no swell to push anything.
You’ll be staring at a long, flat gap with nothing worth paddling for. Water temp is normal for the season, so no surprises there.
Finally, around Saturday, August 8th and Sunday, August 9th, we get a tiny pulse. On Saturday afternoon, the combined surge hits 81, and we see 2ft of ENE swell with a 9-second period. The wind is light and cross-offshore, so the waves at the jetty will have some shape. It’s not big, but it’s the first real chance of the whole run.
The best window, though, is Sunday morning, August 9th. The wind goes dead glassy out of the south. The swell is small at 0.9ft, but with a mirror-flat ocean, those little ENE pulses will look clean and rideable. The jetty can focus that energy, so if you’ve got a log or a fish, this is the time.
After that, it’s back to tiny, onshore chop. The jetty can get packed when it’s on, but for this forecast, you won’t have to fight for a wave.
Rusty.
