The Lowdown
Alright folks, Rusty here. Let's be straight with you. I've been staring at the charts for Jupiter Inlet South Jetty and, to be honest, it's looking pretty grim for the next couple of weeks. We've got a long stretch here where the conditions just aren't in our favour for a decent paddle. There are no standouts on offer, so we'll run through the whole period to give you the full picture.
We kick off Friday morning, August 7th, with a weak 4ft ENE swell running at a short period of 6 seconds. The wind is cross-onshore from the SE at 12 mph, making things choppy. The combined energy is a weak 124, and it's really just poor surf all around. That trend holds through the weekend and into the start of the next week. The swell drops right off, with Sunday morning seeing just 1ft at 7 seconds, and the wind staying mostly cross-on. You might see a bit of shape on Saturday afternoon when the wind turns a little more onshore, but the swell's dropping to 2ft, so there’s not much to work with.
Monday and Tuesday are flat to tiny, with anything from 0.7ft to 2ft. The energy figures are pitiful, dropping to single digits at one point on Monday afternoon (9). We do get a glass-off on the Wednesday morning of the 12th, with zero wind and a glassy surface, but the swell is a measly 0.3ft. You'd be floating out there. Thursday morning the 13th gives us a very light offshore from the WSW at 3 mph and clean conditions, but again, it's only 0.3ft. That's just not ridable.
We limp through the rest of the second week. The swell tries to pick up a little around the 15th and 16th, hitting around 3ft from the SE, but the cross-onshore wind keeps it jumbled and messy. Another glassy moment appears on Monday morning the 17th, with zero wind and a 0.7ft ESE swell at a longer 9 second period. That longer period is nice for quality in theory, but at that size, there's just no push. The last week of the outlook (from the 19th to the 22nd) shows a bit more onshore wind and swell hovering around 2ft to 3ft from the ESE and NE. The energy finally gets back above 50, hitting 61 on Saturday the 22nd afternoon, but the wind is fresh and onshore. It's a windswell setup that's more suited for a kite or a foil than a standard surfboard.
Honestly, for a spot that’s fairly exposed, this is a poor run. There is no day in this 16-day window where the stars align to give a quality wave with clean winds. The water temp is sitting at 85°F, which is about normal for this time of year, so at least you can have a nice swim.
Hang in there, the forecasts can always change. As it stands though, leave the boards at home.
Rusty.
