The Lowdown
Alright folks, Rusty here. Let’s cut to it. The outlook for our go-to, Jupiter Inlet South Jetty, is a tough one. We’re in for a long dry spell before we see anything that’s actually worth paddling for.
The first week and a half is pretty much a bust. We’ve got weak, small swell and a persistent cross-onshore wind that’s going to keep things choppy and ugly. On Thursday the 10th, we had a tiny 3ft NE swell with a short period, and the cross-on breeze just cleaned out any chance of a decent wave. The combined energy is in the low double digits (95). That’s the story for days. The water is a bit warmer than usual for this time of year at 86°, but that’s about the only positive. If you want to kite, you could have fun, but for a paddle surfer, this is a solid "stay home."
It isn’t until Monday the 22nd that we see a real pulse of energy. Swell from the NE builds to around 5ft, and the energy hits 270. But the wind is screaming from the NE at 31 mph, making it a blown-out mess. You don’t want to be out there.
The one and only stand-out window comes on Wednesday the 23rd. The wind finally plays ball, swinging offshore from the WNW. For the morning, it’s going to be clean. The swell holds at 4ft from the NE, with solid energy (209). The period is still short at 8 seconds, but that offshore wind will make a huge difference. It’s a little bigger than 5ft so it’ll be one for the advanced crowd only. Thursday the 24th and Friday the 25th keep the size between 4ft and 5ft, but the wind goes cross-shore and the period drops, so the quality will fade.
If you want a wave in this forecast, your one real shot is the morning of Wednesday the 23rd. The rest is a long, boring wait. It happens sometimes.
Catch you on the beach,
Rusty
