The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Right off the bat, I gotta be straight with you – it’s a drought. We’re looking at a solid 16-day stretch, from the 29th of August all the way through the 13th of September, and there isn’t a single session worth paddling out for. Not one. The swell is tiny, the wind is mostly rubbish, and the energy just isn’t there.

The first few days around the 29th and 30th of August are a total write-off. We’re talking wave heights of 0.7ft to 3ft with short-period, weak windswell coming from the east and southeast. The wind is onshore or cross-onshore, making it messy and choppy. The combined energy is pitiful, sitting at only 23 to 47 (weak energy). It’s just not surfable.

That pattern just drags on through the first week of September. The first few days of the month are more of the same: tiny waves, onshore wind, and poor conditions. The swell energy barely cracks 40 on a good day. It’s frustrating.

We do get a couple of glassy mornings on the 5th and 6th of September, which is a tease. The wind drops to nothing, and the surface is clean. But the swell is still only 1ft with a period of just 4 to 5 seconds. It’s ankle-biters with no push. You might get a wobble, but you won’t get a ride.

The second week is just as bleak. The 7th through the 13th of September shows the same story: tiny swells, mostly from the east and southeast, with heights lingering around 0.3ft to 1.0ft. Energy levels are in the single digits and low teens. Even the glassy moments on the 11th and 12th of September can’t save it because there’s simply no wave to surf.

The only break in the file is Jupiter Inlet South Jetty, and it’s not bringing anything to the table. It’s an advanced spot, fairly consistent, but when the swell is this flat, even the jetty can’t work its magic. The water temperature is about what you’d expect for this time of year, so no surprises there.

The wind is mostly onshore, with a few brief windows of light or glassy conditions, but the swell is too small to do anything with. For a beach/jetty setup like this, with such weak swell and frequent onshore wind, it honestly looks more interesting for kite surfing than paddle surfing right now. There’s just not enough push for a proper wave.

Sometimes you get a blank run like this, and it’s normal for the area when the tropics are quiet. Don’t lose hope, though – forecasts can change, and it tends not to stay this flat forever.

Rusty.
