The Lowdown
Alright, let’s talk about the next couple of weeks at Jupiter Inlet South Jetty. Honestly, it’s a bit of a flat spell we’re looking at. There’s no surf on the table right now, and we’re staring down a long stretch of small, messy conditions. If you’re desperate for a paddle, you’re going to be disappointed for a while.
The water temp is sitting at 87°F, which is a touch warmer than usual for this time of year—nothing crazy, but you’ll notice it’s a bit bath-like.
Tuesday afternoon kicks things off with a tiny 1ft NE windswell, but it’s lined up with an onshore ESE breeze and the energy is weak (44). Not worth getting wet. That sets the tone for the next week and a half—nothing but tiny, weak, and mostly onshore or cross-onshore junk.
We do see a slight bump mid-week, Wednesday the 9th and Thursday the 10th, with waist-high at best 3-3ft NE swell, but the period is short, around 8 seconds, and the wind is on it. The combined energy is still weak to moderate (126-138), and the surf is just poor. A couple of small windows Thursday morning with lighter ESE wind might offer something rideable, but don’t expect any glory.
From Friday the 11th through the weekend and into Monday the 14th, it drops back down—swell heights under 2ft, periods dropping to 4-7 seconds, and the energy numbers fall into the teens and twenties. That’s barely a ripple. The jetty’s just going to be a lake.
We’ve got a long, flat, boring gap here. Don’t even bother checking the cam until around Wednesday the 16th. Even then, we’re only seeing 3-3ft from the east, with short 5-second periods and a persistent onshore wind. It’s still poor surf, and the energy is weak (up to 51). Nothing to get excited about.
The following week—from the 17th through the 19th—it’s more of the same. East-southeast swells in the 2-3ft range, short period, onshore breezes. It’s all just wind chop and texture. If you’re a kiter, maybe it looks more interesting than for a surfer, honestly.
Toward the end of the window—Monday the 21st and Tuesday the 22nd—the wind finally swings offshore out of the northwest, which will clean things up. But the swell is still tiny, only 1-3ft, with a short period. The jetty might look glassy, but there’s just not enough push to make it fun.
The final days, the 23rd, show a little more promise with a moderate offshore west wind, but the surf is still just 1-2ft, and everything is too weak to be considered decent.
So, bottom line: there’s no standout session on offer here. This is a full two-week stretch without a single day that gets the heart racing. The only thing you can count on is the water being warm. If you absolutely have to get in, the cleanest looks are the 21st through 23rd with the offshore wind, but keep your expectations low—it’s not going to be a day for the memory bank.
Rusty out.
