The Lowdown
Alright folks, Rusty here. Let’s be straight with you. I’ve looked at the next 16 days for our patch, and I gotta say, it’s a tough one. The word "poor" is everywhere in the data, and for good reason. We’re looking at a long, dry spell with very little to get excited about.
The first real hope doesn’t show up until Wednesday the 16th, and even then, it's a "maybe" situation. Before that, from now through Tuesday the 15th, you’re looking at tiny, weak dribble. We’re talking waves barely breaking 1 ft, mostly from a short-period easterly windswell with energy values in the single digits to teens. It’s just not worth paddling out for anything serious.
Alright, so let’s talk about the one spot that has any pulse at all: Walton Rocks (Power Plant). This beach and reef set-up is the only break putting anything on offer, but it's a real mixed bag.
On Wednesday the 16th, we finally see a bump. The swell jumps a bit, coming from the NE at 3 ft, with a short, punchy period of 7-8 seconds. The combined energy hits the 118 to 120 mark (moderate) which is the best we’ll see all forecast. The problem? The wind is howling onshore from the NE at 15-18 mph. That’s going to turn any potential wave into a wind-chopped, blown-out mess. It’s not a friendly paddle, and honestly, this looks more like a kite-surfing setup than a clean surfing day.
The rest of the week into the weekend stays in the doldrums. Thursday the 17th has a little 3 ft NE swell left over, but the energy drops off (93 to 96) and the onshore winds chop it up again. Friday the 18th gets smaller, and that trend continues right through the end of the month.
There is one funny little window on Saturday the 19th morning. The wind goes dead calm, glassy. The swell, though, is laughable at just 1.0 ft with a 7-second period and energy of 17. It’ll be flat, but if the tide is right and you’ve got a log, you might find a knee-high crumbler at the river mouth section.
After that, it’s a string of tiny, cross-offshore days from the 20th to the 23rd, but the swell energy is just pathetic, never breaking 20. For the rest of the forecast into the 27th, it’s back to onshore winds and tiny surf.
Bottom line: There are no standouts here. The 16th is the biggest, but it’s ugly. If you’re a beginner, this whole 16-day run is a write-off. For the experienced crowd, maybe the early glass on the 19th offers a chance for a longboard session on a micro-wave. Otherwise, we’re in a classic Florida flat spell. It tends not to stay this way forever, and forecasts can change, but right now, the ocean is telling us to take a break.
Rusty.
