The Lowdown

Alright folks, Rusty here. Let’s talk about what’s on the menu for Jupiter Inlet South Jetty over the next couple of weeks.

To be straight with you, this is a tough stretch. We’re looking at a long, dry spell of tiny surf and onshore breezes that just won’t give us a break. The first proper surfable wave doesn’t even show up until Friday, the 7th of August, and even then it’s a bit of a mess. So if you’re jonesing for a wave, you’re going to be waiting a while.

The water temperature right now is sitting at a warm 85°, which is pretty much spot on for this time of year. No surprises there.

Let’s run through it. From Saturday the 25th of July all the way through to Thursday the 6th of August, it’s a wasteland. We’re talking flat, weak, wind-affected slop with swell heights barely scraping 1 ft, and most of the time it’s even smaller. The combined energy is laughable – mostly single-digit or low double-digit values (like 23, 13, 8). You’ll get a few windows of clean conditions when the wind goes light offshore (like Sunday morning the 26th and Monday morning the 27th), but with no swell to push, it’s just flat and glassy. That’s a long wait for nothing.

Now, the one time the ocean tries to wake up is around Friday the 7th of August. The swell picks up a bit, hitting 4 ft from the ESE on Friday morning, and the combined energy climbs into three digits (112). That’s moderate energy, but here’s the rub – the wind is cross-onshore out of the SE at 9 mph, so it’s going to be bumpy, choppy, and messy. The period is a short, wind-swell style 5 seconds, so the waves will be weak and crumbly. This is a spot that’s fairly exposed, but with that short-period ESE swell and onshore wind, the quality just isn’t there. It’s not going to be a clean line-up, and the crowd factor is something to consider – this spot is often busy, so expect company even in average conditions.

For the rest of the weekend of the 8th and 9th of August, it drops back down. Swell fades to 3 ft-3 ft, energy drops to 71 and 53, and the cross-onshore wind sticks around. It’s still not great. The setup is a beach/jetty, and with the wind and weak, short-period swell, honestly, this is looking more like a day for the kite surfers than paddle surfers. The waves are too weak and chopped up for a proper session.

There’s no standout session here. The best you can hope for is the morning of the 7th of August, but only if you’re desperate. The forecast confidence is higher for the near-term flatness, and the long-range blip on the 7th is as uncertain as it is disappointing.

So, I’ve got to call it like I see it. There are no good surf options in this 16-day window. The consistent flat spells and poor wind alignment mean it’s a blank run. For Jupiter Inlet, that’s unusual – it tends not to stay this poor for long, and forecasts can change, but right now, the board stays in the car.

Rusty.
