The Lowdown
Alright, what’s up, it’s Rusty. I’m looking at this 16-day stretch and I gotta be real with you – it’s a barren wasteland out there. We’ve got a whole lot of nothing on the horizon. The energy levels are pitiful, mostly in single digits and low teens in the early going. For example, the combined energy on Monday morning is only 28, and it stays weak for days. There's no two ways about it; this is going to be a test of patience.
We start at the Jupiter Inlet South Jetty on Monday, August 10th. We’ve got a tiny 2ft of southeast swell with a super short 4-second period, but the wind is cross-onshore out of the SE at 9 mph. The water’s a warm 86° which is average for this time of year. It’s just poor, choppy, and messy. Not worth getting wet for.
Tuesday the 11th is even smaller, just ankle-biters at 0.7ft. The wind is lighter but still onshore, keeping things bumpy. Wednesday the 12th has one glassy moment early with a faint SW wind, but the swell is only 0.3ft. You’d just be bobbing around out there. Thursday the 13th stays tiny with a cross-shore wind, and the afternoons have a chance of thunderstorms.
The weekend doesn’t get any better. Saturday the 15th sees the swell bump up to 3ft from the southeast, but the period is a sad 5 seconds and the wind is a moderate cross-onshore at 12 mph. This is just going to be a mess of closeouts and chop. Sunday is pretty much the same, and the swell fades again.
Now, Monday the 17th, the wind finally goes light offshore from the W, and it looks like the water will clean up. But, there’s practically no swell – only 0.7ft. It will be pretty, but flat. We have a few more clean mornings around the 18th, 19th, and 20th with decent wind, but the swell is still tiny and weak. The max energy we see is 42 on the 19th afternoon. It’s all tease, no reward.
We see a small bump around the 22nd with 2ft from the SE, but at 4 seconds, it’s junk. And that afternoon wind kicks back up. The last few days of the forecast are just more of the same – small, onshore slop.
So, plain and simple: there is no standout surf in this entire 16-day stretch. The Jetties are inconsistent, and with no real swell and a constant onshore flow, this is looking more like a kitesurfing forecast than a surfing one. We are in for a long, flat spell. But that’s the nature of this place sometimes. It won’t be flat forever, and forecasts can shift. Keep your board nearby and be ready when something finally shows up. This is Rusty, out.
