The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next couple of weeks are looking flat as a pancake for our stretch of coast. We’re talking about Jupiter Inlet South Jetty, and honestly, there’s barely a ripple on offer.
Right from Monday afternoon, August 3rd, it’s tiny. We’re looking at a weak 0.7ft swell out of the east with a short period of 8 seconds and combined energy of just 13 – that’s whisper-quiet. The water’s sitting at 85°, which is pretty average for this time of year.
Tuesday morning, August 4th, sees the wind go dead calm – glassy conditions – but the swell remains a pathetic 0.7ft from the ESE. You could paddle around on a longboard but you won’t be catching anything worth writing home about. By Tuesday afternoon, a risk of thunderstorms rolls in with a light onshore breeze, swell bumps up to just 1.0ft but the period drops to 7 seconds.
Wednesday the 5th gets a bit more active wind-wise, but the swell stays under 2ft with periods as low as 4 seconds. That’s windswell junk, not proper surf. The combined energy struggles to hit 13. The pattern doesn’t change much – Thursday through Sunday sees a slight increase to maybe 4ft on Friday morning, but the period is still a short 5 seconds, and the wind is onshore or cross-onshore. Energy barely gets into the 62-85 range, which is weak.
The entire second week, from August 10th onward, is a total write-off. We’re looking at swells under 3ft, periods of 4-5 seconds, and wind states that are mostly onshore or cross-onshore. Nothing worth loading up the boards for.
The only tiny glimmer is way out on Tuesday, August 18th. The swell direction shifts to the NE, picking up to 3ft with a period of 7 seconds and energy of 72. The wind is light cross-onshore. It’s still poor surf conditions according to the charts, so don’t get your hopes up.
There are no standout days here. Not one. The best advice I can give is to leave the boards in the car, maybe take the kite out if you’re into that because the beach setup with the wind might be more interesting for that crew. Forecasts can always change, but for now, it’s a long gap of nothing.
Stay patient.
Rusty.
