The Lowdown
Alright, folks, Rusty here again. Let’s break it down in the old-school numbers. This 16-day stretch is a total bummer. We’re looking at a long, flat patch from now through the 20th of August, with hardly any surf to speak of.
The only spot on the map is Jupiter Inlet South Jetty, and even it’s struggling. The water’s sitting at a warm 85°, which is pretty average for the season.
Kicking off the first week, from Wednesday the 5th through the 12th, it’s all tiny and weak. Swell heights are barely 0.7ft to 4ft, with short periods of 4 to 7 seconds. The wind is a mess—mostly cross-onshore or onshore, with some thunderstorms thrown in. The combined energy is tiny, from 7 to 91 (weak energy). Not worth paddling out.
The middle of the run, from the 13th to the 16th, doesn’t get any better. Swell heights are still 0.3ft to 3ft, and the wind is still cross-onshore or onshore. The energy is even lower, maxing out at 36 (weak energy). There’s a couple of glassy mornings on the 12th and 17th, but with that little swell, it’s just flat.
The final few days, from the 17th to the 20th, are more of the same. Tiny bumps of 0.7ft to 3ft, short period, and mostly onshore or cross-onshore winds. The energy is negligible, never breaking 45 (weak energy). You’d be better off looking for a kite session.
The best bet might be the morning of the 17th of August, when the wind goes glassy. But even then, the swell is only 2ft from the SE with a 5-second period. It’s a long shot, but if you’re itching, that’s your window.
Rusty, signing off.
