The Lowdown
Alright folks, Rusty here, checking in on the local surf scene. Let's be straight up about what we're working with for the next couple of weeks.
Right off the bat, I gotta tell ya, it’s a tough stretch for paddle surfing at Jupiter Inlet South Jetty. We’re looking at a real dry spell here. For the first several days, we’ve got practically no swell to speak of, with wave heights barely a ripple at 0.7ft. Combine that with onshore winds and the constant threat of thunderstorms, and the conditions are just plain poor for surfing. The wave energy is minimal, reading only around 10 (weak energy). This flat spell runs all the way from Monday the 14th through to the end of the week.
Now, the water temp is sitting at a balmy 87°, which is a touch warmer than normal for this time of year – a nice detail, but you won't be needing a wetsuit to enjoy these tiny waves.
Things do start to look a bit more interesting heading into the following week. By Wednesday the 16th, we see a bump in swell, but it comes with a cross-onshore wind and a lot of stormy energy, so the surf quality remains poor. The combined swell energy jumps up to 111 (moderate wave energy) on Wednesday morning, but it's messy and short period at 6 seconds.
The only glimmer of hope, and I mean the one and only standout in this whole 16-day window, looks like it could be the morning of Saturday the 26th of September. We’ve got a solid NE swell pushing 5ft, with a period of 9 seconds. The combined wave energy hits 359 (strong wave energy), which means there’s some real grunt in the water. What’s crucial is the wind is light from the NE, making for clean conditions with just a light cross-onshore texture. This is the best looking window we have, but keep in mind it’s a week and a half out, so the forecast is promising but not locked in.
For the rest of that second week, we hover around the 3ft to 5ft range, but the winds are never quite right, staying cross-onshore and keeping things choppy. A few mornings like the 27th and 28th of September have a glimmer with lighter wind, but it’s still only "marginal" at best.
So, the long and short of it: keep your expectations low for the next week. The real potential is that Saturday the 26th of September, but it's a long ways off. Stay tuned, and keep an eye on the sky.
Rusty.
