The Lowdown

Alright, Rusty here. It’s a pretty flat spell coming up for the next couple of weeks.

Honestly, if you are looking for a wave to actually ride, you are not going to find much love in this 16-day window. The whole outlook is filled with "poor surf conditions" and wave heights that won't get you out of first gear. We’ve got a solid stretch of basically no surf starting now through the weekend and into the middle of the next week. The energy is just not there.

Alright, let’s be real, there is only one spot worth blowing the dust off your board for, and that’s Jupiter Inlet South Jetty (Jupiter-Inlet-South-Jetty). It’s a beach/jetty break that’s going to need a bit of a swell bump to work. The water is sitting at 86°F, which is about a degree and a half warmer than normal for this time of year – that's a nice touch if you’re out there.

We have a pretty long wait. The only real pulse of energy shows up way down the line. Around Wednesday the 9th of September, the morning shows a bump of swell from the NE pushing 4ft. The combined wave energy hits 165 (moderate wave energy), which is the most we’ll see. The problem is the period is only 8 seconds, so it’s a short-period windswell, not a groundswell. It gets messy too, with a 9 mph onshore wind making for a choppy mess. It won't be clean, but for a break that’s rated advanced and fairly consistent, it's the most size we’ll get for the experts to try and find a bump out of the chop.

By Thursday the 10th, the swell legs drop back to 3ft from the NE, but again with onshore wind. The energy is still moderate at 162, but the quality just isn't there. It’s going to be a messy, bumpy affair for the few days that have any height.

Don’t get too excited by the occasional glassy morning because the swell is tiny – we’re talking 0.7ft or 1ft. On Saturday the 12th, there’s a glassy morning with the wind dropping to zero from the NE, but with a swell of only 1ft and a period of 8 seconds, you’ll be sitting there floating. The same goes for Sunday the 13th morning with a tiny little bump from the SSE.

For the second week, it’s a write-off. Nothing but ankle-biters. The 16th and 17th of September just show waves around 0.7ft. It's a long, dry spell.

Signing off, Rusty.
