The Lowdown
Alright, Rusty here, and this forecast has me scratching my head a bit. We're looking at the next couple of weeks around Jupiter Inlet South Jetty, and honestly, for all you paddle surfers, it's a bit of a flat spell.
The water's sitting pretty warm at 86°, which is about a degree warmer than usual for the time of year, so at least a dip in the ocean feels good. But the surf? It’s a no-go for quite a stretch.
We start off with the first few days—Thursday the 3rd through the weekend—and there’s just nothing happening. We’re talking tiny, wind-affected dribble. The swell energy is weak, with the combined energy reading under 100 (29 on Thursday morning, for example), and the period is short, around 5 seconds. That’s just wind slop.
That quiet spell stretches all the way through until Tuesday the 8th. There's a glimmer on the charts with a bit more swell energy on the 9th and 10th of September, but it’s all spoiled by onshore winds. The combined energy climbs into the 200s (283 on Wednesday afternoon the 9th) with some 3 ft to 4 ft swell from the NE, but the wind is howling onshore or cross-onshore. That combo will just churn up a messy, choppy lineup. It would look far more interesting for kite surfing than paddle surfing right now.
We then slide into another quiet patch. From the 11th right through until the 17th, the swell drops back down, the energy is low again (mostly under 100), and the wind is mostly onshore. It’s a big blank run of poor surf conditions with no real standouts. The 17th of September shows a tiny bump with combined energy of 108 and 3 ft from the NE, but again, the wind is onshore. It just doesn't come together for a quality wave.
Bottom line: There are no good surf options in this 16-day window. For the Jupiter Inlet area, a blank run like this is more normal during the summer doldrums, so don’t get too bummed. Forecasts can always change, but right now, it’s best to leave the board in the car.
Rusty.
