The Lowdown
Alright folks, Rusty here. Let’s have a look at what we’ve got. I gotta be straight with you – the outlook for our area is a tough one. We’re looking at a long stretch with next to no surf on offer, so don't go getting your hopes up too high.
The first spot that shows up, Jupiter Inlet South Jetty (Palm Beach County), is an advanced wave, but let's be real: across these 16 days, every single reading in the forecast is labelled as poor surf conditions. The swell energy is next to nothing, with the highest combined energy reading hitting only a weak 66 on the 29th of August. For the first week and a half, the swell is tiny, mostly around 0.33 ft to 2 ft, coming in from the ESE or ENE, but the period is often short (around 5 to 8 seconds), so it lacks any real grunt. The water temperature is a warm 87 °F, and sitting about 2 °F above normal, so it’s a touch toastier than usual for this time of year.
We do have a few moments with clean conditions. On the morning of Monday the 18th of August, the wind is light from the west (offshore) at 6 mph, making for a clean 0.7 ft wave, but that tiny 11-second period swell just won't do much. Then on the morning of Thursday the 21st of August, it goes glassy with no wind and a 0.7 ft wave from the ENE at 8 seconds. Again, clean as a whistle, but there’s hardly any wave to ride.
Even the “bigger” days, like Saturday the 29th of August with a 3 ft swell from the ESE at 5 seconds, are riddled with cross-onshore or cross winds making it choppy. For the advanced-level guys, the jetty can offer a shape, but with this lack of size and consistency, it’s just not worth paddling out.
So here’s the plain truth: there are no good surf options in this 16-day window. The stretch of poor conditions runs straight through from the start on August 15th, all the way to August 30th. It’s a long spell of flatness for the Jupiter Inlet South Jetty. This is a blank run, and while it stings to say it, this kind of a dry spell is more normal for the area in a dead summer pattern. Keep your board in the car, but don’t hold your breath – forecasts can change, but right now, it’s all quiet.
Rusty.
