The Lowdown
Alright folks, Rusty here. Let’s get real about the next few weeks for Jupiter Inlet South Jetty. I’ll be straight with you – this is a tough stretch. The forecast is a long, dry spell with nothing to get excited about. We’re looking at a solid 16-day gap with no decent surf. The first week and a half barely has a ripple.
Starting off Wednesday the 2nd through the 3rd, it’s all small, weak windswell – knee-high at best, with onshore or cross-shore breezes messing up any chance of a clean face. Wind energy is basically non-existent (combined energy around 22-32). Come Thursday the 4th and Friday the 5th, the wind picks up but the swell stays tiny and short-period, making it a choppy, sloppy affair. By Saturday the 6th, we get a bit of a clean-up with a light offshore and cross-offshore breeze, but the swell is pathetic – barely 0.7 ft. Sunday the 7th morning has a clean offshore wind (W, 10 km/h), but again, no power behind it.
The only glimmer comes around Wednesday the 9th. The swell bumps up to 3 ft from the NE, with a period of 10 seconds and combined energy in the moderate range (181). But it’s onshore wind (ENE, 15 km/h), so it’ll be lumpy and hard to enjoy. For the next week, from the 10th through the 16th, it’s more of the same: small, weak swells with onshore or cross-onshore wind. A couple of mornings on the 12th and 13th have glassy or light cross-offshore conditions, but the swell is only 0.3 ft to 0.7 ft. You’d be floating.
The last few days into the 17th are still marginal. The swell tries to show up a little on the 16th morning (3 ft, 5-second period from the E), but it’s weak and won’t hold shape. Honestly, there’s not a single standout session in this whole run. The water temp is sitting around 86°, which is about normal for this time of year – not a factor.
For a jetty break that’s already advanced and inconsistent, this is a rough patch. It’s the kind of run where you park the board and check the forecast again next week. Keep your chin up, though – a clean day with a little pulse can sneak in.
Rusty.
