The Lowdown
Alright, surfers, Rusty here. Let’s take a long, hard look at the next couple of weeks for the Jupiter Inlet South Jetty.
Right off the bat, I gotta be straight with you: this is a grim outlook. The forecast is a flat spell from start to finish, with literally no surf on offer worth paddling out for. The first day we see any kind of wave is July 14th, and it’s a tiny 0.3ft with a cross-on wind; that’s not surfing, that’s floating. We’re looking at a solid 16-day stretch with zero recommendations. The wave energy is consistently weak, with values barely breaking into double digits – most days are sitting in the single digits, which is about as weak as it gets.
The whole period is a write-off, but let’s walk through the best of a bad bunch. The closest we get to anything surfable is the morning of July 15th. That Wednesday morning shows a glassy, offshore wind from the NNE at 3 mph, which is a dream for clean conditions. The swell is a tiny 2ft from the NE with a short period of 8 seconds. The energy is still crap at 29. It’s not surfable, but if you were to look at the water, it would at least look pretty. The water temp is sitting at 86°, which is about normal for this time of year.
The same can be said for the morning of July 16th, with a clean cross-offshore wind from the NNW, but again, only 1ft of weak, short-period junk. Thursday morning the 24th shows a little more energy, hitting 20, but that’s still a long way from being rideable, and the wind is cross-on. The 25th of July has the highest energy in the whole run at 30, but it’s still a pathetic 1.0ft. For a spot like this, which is fairly consistent and exposed to the NE, it’s a real bummer. The jetty can handle some size, but we’re not getting any. For a beach/jetty setup with this much wind and no swell, honestly, this looks more interesting for a kite than a surfboard for the next two weeks.
Hang in there, crew. The forecasts can always change, but for now, leave the boards in the shed.
