The Lowdown
Alright, folks, Rusty here. Let’s cut to the chase – we’re looking at a rough patch for the Jupiter Inlet South Jetty.
Scrolling through the whole 16 days, it’s a long stretch of nothing much. The swell is tiny, the conditions are poor, and the sea is just lying there. The combined wave energy is weak, barely reaching 20 (20) in the early part of the forecast, and that’s the best of a bad lot.
For the first week, from Wednesday July 22nd right through the end of the month, it’s a write-off. Swell heights are around 0.6 to 0.7 feet, but it’s short-period, wind-chopped junk. Wind is mostly cross-on or onshore, so it’s messy. A few mornings, like Sunday the 26th, Monday the 27th, and Thursday the 30th, the wind goes light offshore or glassy, but the swell is only 0.2 to 0.3 feet. It’s clean, but it’s not enough to get wet for.
The one glimmer, and it’s a faint one, is on the morning of Sunday, August 2nd. We get a 20 mph offshore wind from the west, but the swell is just 0.2 feet from the east with an 8-second period. The energy is a low 12 (12). It’ll be clean, but you’ll be waiting for a wave that barely shows up. It’s a maybe, not a plan.
Later that afternoon on the 2nd, the wind jumps to a fresh 30 mph offshore, but the swell is only 0.6 feet from the south-southeast with a 4-second period. That’s pure windswell, and it’s going to be weak and bumpy. The energy is 18 (18). Not worth the paddle.
Water temp is 86°F, which is about 0.9°F above normal for this time of year – nothing notable.
So, honestly, there are no good surf options in this 16-day window. It’s a quiet spell. The Jetty normally gets some action, so a blank run like this is a bummer, but it’s part of the deal. Keep an eye on it, but don’t hold your breath.
Rusty.
