The Lowdown
Alright crew, Rusty here. Let’s be straight about the next couple of weeks. It’s a total flat spell. We’re looking at a long stretch of nothing, with days and days of no real surf.
The only break on the map is Jupiter Inlet South Jetty, and the news is all bad. The entire 16 days is filled with poor surf. The water’s a warm 85°F, which is about average for this time of year.
We kick off on Friday, July 31st with a tiny 0.3ft easterly swell, but the wind is offshore from the WSW, keeping it clean. The combined energy is a weak 5, so it’s barely a ripple. That’s the high point, which tells you everything.
Saturday, August 1st sees a bump to 0.7ft from the ENE, but it’s cross-offshore in the morning. By the afternoon, the wind goes onshore from the SE, and the swell hits 2ft but with a terrible 4-second period – that’s just wind chop.
Sunday the 2nd through Tuesday the 5th is the same story: tiny waves, mostly wind-affected. The swell tries to get a little energy on the 4th with a glassy morning and 1.0ft from the ENE, but it’s still poor.
We get a slight uptick on Friday, August 7th. The swell holds at 3ft from the ENE, the period stretches to 9 seconds, and the combined energy hits 111 – that’s moderate energy. But the wind is onshore in the morning and cross-onshore in the afternoon, so it’s going to be a bumpy mess. It’s the only day with moderate energy, and the conditions ruin it.
From there, it’s back to tiny, weak swell. A few glassy mornings on the 8th, 9th, 10th, and 12th of August, with 0.7ft to 2ft of short-period swell, but the energy is weak (between 28 and 50). The 12th has a 0.7ft swell with an 11-second period, which is a longer period, but it’s so small it’s not worth paddling for.
The rest of the run into the 15th of August is just more of the same: tiny, weak, onshore slop. There’s nothing here that’s worth a second look. The Inlet is completely asleep.
This is a classic blank run for the area. It’s normal, but it’s a bummer. Keep the board on the rack, check back later, and maybe take the boat out instead.
Rusty.
