Alright, Rusty here again. Let’s break it down in feet and miles per hour.
Honest truth: the Jupiter Inlet South Jetty is looking pretty dead for the next two weeks. The first recommendation kicks off now, but it’s a long, flat stretch ahead.
We start Wednesday the 8th of July with tiny, weak surf. Waves are only 1 ft from the southeast, with a short period of 4 seconds. The combined energy is a pathetic 10 (weak). To make it worse, we’ve got a cross-onshore wind at 6 mph, putting a nasty bump on the surface. Water temp is 86°, about normal for the season.
From Thursday the 9th all the way through to Tuesday the 22nd of July, it’s just poor. The swell never gets above 3 ft, usually hanging around 0.7 ft to 2 ft, and the period stays short. The wind is almost always cross-onshore from the southeast or east-southeast, keeping things choppy. The energy never hits 50 on the combined scale – it’s flat.
There’s one small moment on Thursday the 23rd of July in the morning: the wind goes light cross-offshore from the southwest at 3 mph, so it’ll be glassy. But the swell is still only 1 ft from the south-southeast with a 4-second period, and energy at 17 – barely a ripple. Not worth paddling for.
Don’t bother. This is a classic summer flat spell. The jetty can handle a bit of direction, but there’s no push. This kind of dead run is just how it goes around here sometimes. Stay patient.
Rusty.
