Table - best surf conditions forecast for Jupiter Inlet South Jetty over the next 16 days.
Alright folks, Rusty here. Let's have a look at what's coming up for Jupiter Inlet South Jetty.
Straight up, I gotta be honest with you – the next two weeks are lookin' flat, real flat. We've got a long, dry spell ahead. The first record we see kicks off on Saturday, July 11th, and from there right through to Sunday, July 26th, there's not a single day that's worth paddling out. That's a solid 16-day stretch of nothing but tiny, weak dribble. The combined swell energy is next to nothing, with most readings sitting below 30 (weak), and just a few days barely tickling the 20s. It's a tough run for this area.
The water temp is sitting at a warm 86°F with an anomaly of 1°F, so pretty average for this time of year down here.
You'll see little pulses of 1 ft to 3 ft swell from the SE and NE directions, but the period is always short – 3 to 8 seconds. That's just windswell mush, no grunt behind it. There's no standouts, no best on offer, just a whole lot of "poor surf conditions" across the board. Winds are mostly cross-on or onshore, keeping things choppy and messy. The only bright spots are a couple of glassy or clean mornings on Thursday July 16th and Friday July 17th, but with only 1.0 ft to 1 ft of swell, you'd be chasing ankle-biters.
Forget the board for a while. If you're a kiter, that Saturday afternoon July 25th with 12 mph cross-onshore winds and 2 ft messy swell might be more interesting, but for a paddle surfer, it's a blank run. Forecasts can always change, but as it stands, this stretch looks like a write-off.
Stay tuned, Rusty.
