The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this 16-day window around Jupiter Inlet South Jetty is a tough one. The swell just doesn’t show up with any real energy or decent direction, and when it’s not flat, the wind is messy. We’ll be looking at a long stretch of small, weak, and often choppy conditions. The good news? The water is sitting at a warm 85°, which is pretty much bang on average for this time of year, so at least you won’t need a thick suit.

The first recommendation doesn’t come until Sunday morning, August 2nd, and even then it’s a real struggle. A tiny 0.7ft ENE swell with an 8-second period is all we’ve got, with a weak energy reading of just 7. The wind is a cross-off from the SSW at 9 mph, which keeps the surface clean, but there’s just no wave to ride. This pattern of small, poor surf continues straight through the first week. Monday morning (August 3rd) gives us a glassy 0.7ft E swell, but it’s another dud. By Wednesday the 5th, the swell bumps up to 2ft from the SE, but with a short 4-second period and a moderate cross-onshore wind at 12 mph, expect choppy, weak waves. The energy creeps up to 24, but it’s still not enough.

We see a slight bump in size on Thursday the 6th, with a 3ft ESE swell and a 5-second period, but it’s onshore and messy. That energy climbs to 56, but the quality is poor. Friday the 7th sees the biggest push of the period – a 5ft E swell with a 6-second period, and the combined energy hits 129. But with a moderate onshore wind at 16 mph, it’s a choppy, blown-out mess. This is honestly more interesting for kite surfers than paddle surfers. Saturday the 8th offers a 3ft ENE swell with an 8-second period and a cleaner morning – the wind is a gentle onshore from the ENE at 9 mph, but the energy is decent at 166. Still, the onshore wind and lack of a clean pocket make it a tough call.

After that, the second week is a real drag. From Sunday the 9th all the way through to Monday the 17th, the swell stays tiny, never cracking 4ft, and the period is short (4-7 seconds). The wind is almost always cross-onshore or onshore, from the SE or ESE, at 9-16 mph. The energy readings are low, mostly in the teens or under 100. The only glimmer is on Monday morning, August 17th, when the wind goes glassy from the SW at 3 mph, but the swell is just 0.7ft from the E with an 8-second period – it’s a flat, glassy morning. There’s simply nothing to get excited about.

If you’re a beginner, the swell never gets big enough to worry about, but it’s also never good enough to learn on. The jetty is a fairly exposed break, but the swells are all coming from the wrong direction (ESE, SE, E) when the optimum is NE. The crowds are often an issue here, but with surf this poor, you’ll have the place to yourself. It’s a blank run, plain and simple.

Rusty.
