The Lowdown

Alright folks, Rusty here. I’ve had a good look at the charts for Jupiter Inlet South Jetty, and I gotta be straight with you – it’s a tough stretch. The next couple of weeks are looking pretty flat and sad, with barely a ripple to get excited about. We’re looking at a long dry spell here, so don’t be in a rush to load up the boards.

The pattern starts off with a weak, short period swell from the SSE on Monday, July 20th, but it’s a total write-off. We’re talking a tiny 3 ft max with a crappy 4-second period, and the wind is a messy cross-shore. The combined energy is weak as dishwater at just 31. It’s the same story through Tuesday and Wednesday – tiny swell, onshore or cross-onshore breezes, and just poor, choppy conditions. The swell drops to almost nothing by Thursday the 23rd and Friday the 24th, with combined energy values barely above 5 and 16. Honestly, it’s not worth paddling out for.

We do finally get a bit of a reprieve on Saturday, July 25th. The morning is glassy calm with a light 1 ft, 8-second swell from the ENE. The wind is dead flat, so the surface will be like a mirror, but the energy is still super weak (26). This is really the only window in the first week that might give you a cruisy, small-wave session on a longboard. Saturday afternoon gets a bit of a cross-on breeze, so hit it early.

Sunday the 26th through to the end of July stays pretty flat. A few mornings see a light offshore wind (WSW or W) which will clean up the 0.7 ft to 1.0 ft dribble, but it’s barely surfable. The energy is in the single digits or low teens. Friday, July 31st, has a glassy afternoon with a 0.7 ft, 9-second swell, but it’s just too small.

As we flip into August, there’s a slight increase in activity on Saturday the 1st and Sunday the 2nd, with a SE swell bumping up to 2 ft and 3 ft and the combined energy getting into the 30s and 40s. The period is still short and weak (4-5 seconds), and the wind is mostly cross or cross-on, so it’s going to be a messy, lumpy mess. The final few days show a bit of energy from the NE, but the wind is onshore and the quality is poor.

So, the only standout here is Saturday morning, July 25th. The glassy conditions are a major positive, but don’t expect any power. For a spot that’s fairly exposed, we just aren’t getting any love. The water temp is about average for the time of year. This is a long stretch of quiet water, so it’s a good time to do some maintenance on your gear.

Rusty.
