The Lowdown
Alright, Rusty here. Let’s have a look at the next couple of weeks for us.
Truth be told, it’s a pretty grim stretch for the South Jetty at Jupiter Inlet. We’re looking at a long, slow run of small, choppy, and mostly onshore junk. There isn’t a single standout session in the whole 16-day outlook. The first solid recommendation doesn't even show up for a while because the surf is so small and weak. We’re essentially looking at a two-week gap of poor conditions.
Starting from Sunday the 30th of August, it’s all tiny, wind-affected slop. Swell heights are hovering around 0.7 ft to 2 ft (0.2m to 0.5m), with periods so short they’re barely breaking. The wind is mostly onshore or cross-onshore from the east and southeast, keeping the surface messy and bumpy. The combined energy is weak, sitting in the low teens to 40s – that’s the sound of nothing happening.
Toward the end of the first week and into the second, we get a brief tease of a little more size around the 3rd and 4th of September. Swell bumps up to 3 ft to 3 ft (0.8m to 1.0m) from the ESE and SE, but the period is still a weak 5 seconds. The wind is a moderate cross-onshore, making it choppy and hard to love. The energy lifts to a ‘moderate’ reading of 83 and 67, but the quality just isn’t there – it’s a mess.
Things go totally flat again from the 5th of September onward, with swell barely scraping 1 ft (0.4m) and energy readings falling into single digits. There’s a glassy morning on the 7th of September, but with a 0.3 ft (0.1m) swell from the NE, it’s basically a lake. The best wind we see is a glassy or light cross-offshore window on the morning of the 11th of September, but it’s over a paltry 0.3 ft (0.1m) of swell from the SE. Not worth paddling for.
That little uptick on the 14th of September (Monday) shows 3 ft (1.0m) from the NE with a 6-second period, but the wind is onshore ENE at 15 km/h. The energy reading of 66 is still moderate, but the conditions are poor.
Honestly, for this stretch, you’re not missing much if you hang up the board. The jetty needs a better swell direction and some clean wind to fire, and we’re not getting either. For a break this exposed, it’s a real bummer. If the wind holds onshore and the swell stays weak, this setup might actually be more interesting for kite surfing than paddle surfing, if that’s your thing.
Keep the faith, though. Small spells like this don’t tend to last forever around here.
Rusty.

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.
