The Lowdown
Alright, Rusty here. Let’s take a look at what we’ve got for the next couple of weeks.
Honestly, I’m scratching my head a bit. There's no real surf to speak of on the horizon right now - it's a flat spell for sure at Jupiter Inlet South Jetty. We’re looking at a long, dry gap: from now all the way through to about Wednesday, August 27th, the waves are barely a ripple. Most days the swell is sitting at 0.3ft to 2ft, with weak combined energy readings - mostly in the single digits or low double digits - which is about as exciting as a flat tyre. The wind is either onshore or choppy cross-onshore, so even those tiny bits of swell are blown out junk. There’s a few glassy windows early in the run (like Wednesday August 12th morning and Tuesday August 18th morning) but with 0.3ft to 0.7ft of swell that’s more of a bath than a surf.
Things start to show a faint pulse around Tuesday morning, August 25th. The swell ticks up to 2ft from the NE with a period of 7 seconds. The combined energy barely reaches 30 - weak, but it’s the first number with some weight behind it. Still, the wind is cross-onshore all day, so it’s going to be lumpy and bumpy. Hard to get excited.
The real window, if we can call it that, lands on Thursday morning, August 27th. The morning is glassy again - SE wind at just 3 mph - and strong NE swell direction is where this spot wants it (optimum is NE). The period is 7 seconds, still short, but with 1ft and glass, that's the cleanest you are likely to see. Combined energy sits at 24 (weak still). This won't hold a clean line, but for an advanced surfer on a longboard or a foiler, there might be something knee-high and tidy.
This break is East Coast beach/jetty, and it's fairly exposed to swell, so it *can* light up. But right now, there's no real swell energy. The water temp is 86°F, which is about average for the time of year, so a warm dip at least.
For the advanced crew, the 27th morning is your best bet. For everyone else? It’s a long, flat gap until then. A blank run like this is normal for the area this time of year. Could change. Fingers crossed.
