Jupiter Inlet South Jetty Surf Forecast and Surf Report

Well, to be blunt, the next week and a half at Jupiter Inlet South Jetty is looking pretty grim. We’ve got a whole run of tiny, weak swell – nothing over `0.2m` to `0.5m` for the first stretch, with periods down around `7` to `9` seconds. That’s just not doing anything for us. The water’s warm, sitting at `30°`, which is a touch warmer than normal for this time of year, but you won’t be feeling it while you’re just bobbing around with nothing to ride.

The wind isn’t helping either. For most of this first week, it’s onshore or cross-onshore, with a bit of chop and bump. There are a couple of glassy moments early on – Sunday and Monday mornings are dead calm or light – but the swell is just non-existent. It’s a frustrating combo: clean surface, but nothing underneath.

We finally see a bump in the swell around Wednesday the 16th, with `1.7m` to `1.9m` pushing in from the NNE/NE, and the energy jumps to `358` to `394`. But it’s all chopped up by a solid `25 km/h` cross-onshore wind. Same story on Thursday – still over a metre of swell, but the wind has it all mushy and messy. Forget it.

Friday the 18th and Saturday the 19th drop back down to under a metre, and the wind is still not your friend. Honestly, the first nine days are a write-off.

Now, here’s where it gets interesting. The 23rd of September is where things finally click. We’ve got a pulse of `1.6m` to `1.8m` from the NE, and the energy is building – `479` to `542`. That’s moderate energy, but the key is the wind: it swings offshore, light and clean. The jetty will start to shape up proper. Morning of the 23rd looks the pick, with a light `15 km/h` cross-offshore breeze and clean conditions.

The 24th is even better in terms of wind – light offshore from the W at `10 km/h`, with swell holding at `1.6m` to `1.8m` from the NE. Clean, lined-up, and the jetty should be doing its thing. This is looking like the standout morning of the whole outlook.

Then the 25th – this might be the biggest day. We’re looking at `2.0m` to `2.1m` of NE swell, still with that light offshore wind out of the W, and the energy is cranking – `615` to `625`. That’s strong energy, and it’s going to be pushing a lot of water through the jetty. This is the one to circle in the calendar. It’s still a week and a half out, so don’t book the day off work just yet, but if it comes together, it could be the best surf we’ve seen in a long while.

The 26th drops back a touch to `1.4m`, but the wind is still offshore or cross-offshore, keeping things clean. A solid, fun day, but the 25th is the standout.

After that, it’s back to the same story – onshore winds and choppy conditions from the 27th onward. The swell is still around `1.2m` to `1.4m`, but it’s messy and not worth the paddle.

So, bottom line: if you can wait, the window from the 23rd to the 26th of September is where it’s at. The 25th is the pick of the bunch – biggest swell, clean conditions, and the jetty will be firing. It’s a long way out, but that’s the one to keep an eye on. Before that, don’t bother.

Rusty.
