The Lowdown
Alright, this is Rusty, and I'm looking at the outlook for the next couple of weeks. Honestly, it's a bit of a slow stretch for the most part, but we've got a little window of hope tucked away in the second week.
The whole 16-day window kicks off on Wednesday, July 29th, and we’re looking at a long, dry spell. Right through to the morning of Saturday, August 8th, it’s a real struggle. We’re talking over a week of tiny, weak waves and crummy conditions. The swell is barely a ripple, with combined energy stuck in the single digits (7) and wind is not doing us any favors. It’s a desert out there.
Then, the morning of Saturday, August 8th finally shows a pulse. `Jupiter Inlet South Jetty` gets a lift with a 3ft swell from the ENE, with a period of 10 seconds, and the combined energy jumps to 243 (moderate). The wind is light off-shore, making for clean conditions. It’s surfable, but the wave comment says "very ordinary conditions," so don't expect a classic. It's a bit of a tease, but it’s the first real sign of life.
The real standout, though, is the morning of Tuesday, August 11th. This is the best we’ve got. The swell is a consistent 4ft from the NE, with a 11-second period, and the combined energy is a solid 268 (moderate). The wind is a glassy, light offshore from the W, so the face will be silky smooth. The wave comment even says "expect good surf conditions." This is the one. For an advanced spot like the Jetty, this is going to be a proper session. Shortboarders, get on it. This is a long period groundswell, so it'll have some punch, and the clean conditions will be a blessing.
After that, Wednesday the 12th and Thursday the 13th mornings still offer some knee-to-waist high NE swell (3ft) with clean off-shore winds, but the energy is a little lower (195 and 164). It’s still surfable, but Tuesday morning is the clear winner.
The water temperature sits at around 86°F, which is about normal for the time of year, so you can go in boardies.
Rusty.
