The Lowdown
Right, well, lookin' at the forecast for the next sixteen days, I gotta be straight with you… it’s a bit of a flat spell for the Jupiter Inlet South Jetty. There’s barely a ripple to get excited about, and the whole stretch is a write-off for surfers.
The first week is a total dud. From Sunday the 26th to the 6th of August, we're looking at ankle-snappers at best. The swell heights are tiny, from 0.3ft to 3ft, and the combined wave energy is pitiful, with the highest reading hitting just 44 (the entire period is in the weak range). The wind is all over the place—offshore, cross-off, and glassy at times—but with no swell to work with, it’s like a beautiful engine with no gas. The water temp is about average for the time of year, so nothing to write home about there either.
The one bright spot is the quality of the wind windows. You’ll see clean conditions on several mornings, like Monday the 27th with a light offshore, and Wednesday the 29th with a moderate offshore. But honestly, with waves that small, it’s just a nice day at the beach, not a surf session.
Moving into the second week, from the 7th to the 10th of August, it’s more of the same. The swell stays pathetic, with the occasional 2ft bump from the south or east, but the period is super short at 4 to 7 seconds. That’s just windswell, no push. The wave energy is still weak, never breaking 24. The winds are generally onshore, adding a bit of chop to the mix. A glassy morning on the 8th of August is as good as it gets, but again, with 0.6ft of swell, it's a flat day.
So, honestly, there is not a single standout in this entire 16-day window. The whole forecast is a “poor surf conditions” report card. The best you can say is that the jetty will be clean at times, but there’s no wave to ride. If you’re a kite surfer, maybe the bigger wind days in the first week could offer something, but for a paddle surfer, the forecast is a blank run. This is pretty normal for the area during this quiet season, so don’t get too down about it—forecasts can change.
