Jupiter Inlet South Jetty Surf Forecast and Surf Report

Hey, Rusty here again. Let’s talk about the Jupiter Inlet South Jetty (Jupiter Inlet South Jetty) for the next couple weeks. To be straight with you, the start of the run is weak sauce. From Wednesday the 16th on through the weekend, there’s not much on offer. The wind is a messy cross-onshore at 12 to 16 mph, and we’re seeing a lot of storm clouds and choppy, short-period junk. Swell heights are between 2 ft and 5 ft, but it’s all over the place. The combined energy is weak to moderate, reading between 42 and 296. It’s just not worth the paddle.

The early part of next week, Monday the 22nd and Tuesday the 23rd, is still gutless. The swell drops, the wind turns straight onshore, and we’re left with ankle-biters and a lot of nothing. The energy readings are down around 22 and only picking up to 80. It’s a bummer.

Things start to pick up a little from the 23rd, but it’s still not clean. We get a bump of ENE swell, with size coming up to a consistent 5 to 6 ft, and the energy climbs into the moderate range, 191 to 491. But the wind is still onshore, blowing 16 mph or more, making it lumpy and bumpy. The period is short, around 6-7 seconds, so it’s not going to have any punch. It’s surfable for a log, but don’t expect any gems.

Now, here’s the reason you keep your eyes on the horizon. Monday the 28th of September is the big one. We’re looking at a massive jump. The swell hits 16 ft in the morning and goes to 18 ft in the afternoon. The combined energy reading is an incredible 4220 and then 6228. This is a serious, powerful groundswell with a 10-second period. It’s a cleanup day for sure, only for the most experienced chargers. The wind is onshore at 16 mph, which will put some texture on it, but with that kind of size and power, it’s going to be heavy.

Tuesday the 29th is still monumental. The swell is a staggering 15 ft in the morning and 11 ft in the afternoon, with a very long 11-second period. The energy is off the charts at 4658 and 6602. The word is, it’s too big for this spot, which is saying something. Even when it backs off on Wednesday the 30th to around 8 ft, it’s still a solid, powerful pulse that’s not to be taken lightly.

So, the first ten days are a write-off. But mark your calendar for the 28th and 29th. That’s the window for the real deal. It’s a distant forecast, so don’t bet your life on it, but it’s got the look of a proper big-wave event. If you’re not an expert, stay on the beach and watch the show. This is Rusty, out.
