The Lowdown

Alright, this is Rusty, and I gotta be straight with you... the next couple of weeks are looking pretty bleak for a paddle.

For the next 16 days, starting now, there’s basically nothing on the table. We’re looking at a long, frustrating stretch of tiny, weak surf. The only spot that ever gets a mention is the Jupiter Inlet South Jetty. It’s an advanced spot, but it’s rarely breaking, and even when it does, the conditions are just not there.

The first real chance of anything rideable doesn't show up until well into the second week. The water temp is sitting around 87°, which is a touch warmer than usual for this time of year, but nobody’s gonna be worrying about that with no waves.

The whole run is plagued by tiny swells, mostly from the east and northeast, barely scraping 0.7 ft for the first week. The energy is pathetic, with values like 12 (12) or 19 (19) – that’s barely a ripple. Winds are mostly light and variable, with some glassy moments on Tuesday the 18th afternoon, but there’s nothing for that wind to work with.

Things start to look a little less terrible around the 28th of August, with a few morning sessions showing a cross-offshore breeze from the southwest, and the swell trying to pick up a bit. On the morning of the 29th, we get a rare offshore wind from the WSW, with the swell holding around 1.0 ft from the ENE with a period of 10 seconds. The combined energy is still weak at 31 (31), but it’s the best we’ve seen. By the 30th of August, the swell nudges up to 1 ft and the energy hits 45 (45) – still small, but the early morning on the 30th has a clean look with a light cross-offshore breeze.

If you absolutely have to get wet, the first few days of September are the only window that might offer something. The morning of the 1st shows a 2 ft swell from the ENE at 8 seconds, with light cross-onshore winds from the ESE. The energy is up to 57 (57) – the highest in the whole forecast, but it’s still a tiny, short-period windswell with a messy wind. The 2nd of September morning is similar with 1 ft from the NE, but the wind is a stronger ESE at 12 mph, making it choppy.

Honestly, for a spot that’s already fairly inconsistent, this is a pretty normal blank run. The forecast can change, but right now, it’s a hard pass. The setup here is more interesting for kite surfing than a traditional paddle session.

This is Rusty, signing off. Better luck next time.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions.

Further information to help with frequently asked questions about our surf forecast for Jupiter Inlet South Jetty may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
