The Lowdown
Alright folks, it’s Rusty here. Let’s be real: this next couple of weeks at Jupiter Inlet South Jetty is looking flat. Real flat. We’re in for a long stretch of tiny, weak surf that’s barely gonna register. The good news? It’s not gonna stay like this forever, but for now, you can leave the big boards at home.
We’re starting off on Friday, July 31st, with nothing. A measly 0.3ft of easterly windswell, with a short period of 10 seconds. The combined energy is a pathetic 3 (weak energy). Total write-off. The water temp is about average for this time of year, so no surprises there.
The weekend isn’t any better. Saturday, August 1st, we’ve got 0.7ft from the ENE at 9 seconds. The energy is up to a whopping 9 (still weak) but the wind is off in the morning, making it clean. It’s still tiny, though. By the afternoon, the seabreeze kicks in from the ESE, making it choppy. Sunday, August 2nd, is more of the same: 0.7ft, 8 seconds, weak energy (13), and cross-shore winds.
We roll into the next week with a slight bump. Monday, August 3rd, the swell nudges up to 3ft from the SE, but the period is a short 5 seconds, so it’s all windswell junk. The energy is 45 (still weak), and the wind is cross-shore, creating some chop. Tuesday, August 4th, is a funny one. The morning goes glassy, totally calm wind, but the swell is back down to 2ft at 4 seconds. It’s clean, but it’s gutless. The afternoon gets ruined by onshore wind.
The next week continues the same story. Wednesday, August 5th, through to the weekend of August 8th-9th, we see a few days with 2ft to 3ft swell, but it’s all short-period, wind-driven slop. The energy levels stay in the weak to low-moderate range (39 to 57) but the quality is just not there. The wind is a mess, mostly cross-onshore or onshore, making it choppy and bumpy. On Sunday, August 9th, the morning goes glassy again with a 2ft swell, but it’s still 4-second junk.
The second week, from August 10th through the 15th, is a flat bust. The swell drops back to 1ft to 2ft, all short period, with energy levels tanking again. There are a few glassy windows, like the morning of Monday, August 10th, and the morning of Saturday, August 15th, but the surf is too small to do anything with. The combined energy on the 15th is just 6. There’s simply nothing to get excited about.
For a spot that’s fairly exposed and needs a decent NE pulse to work, this is a long, dry spell. If you’re a kiter, you might find something to do on the windier afternoons, but for paddling, it’s a no-go. The best of a bad bunch is the glassy mornings with the tiny peaks, but honestly, it’s hardly worth the paddle out.
Rusty.
