The Lowdown
Alright folks, Rusty here. Let’s be straight with you: the next couple of weeks around here are looking pretty flat and grim. There’s just no real energy showing up to get excited about. We’ve got a long stretch of poor conditions ahead, so don’t be in a hurry to grab your board.
Looking at the whole 16-day window, it’s a tough one. The first solid week is basically a write-off. From Friday the 7th of August right through to the end of the following week, the swell is tiny and the wind is mostly onshore or cross-onshore, making a mess of things. You’ll see a bit of weak, short-period windswell from the east and southeast, but it’s barely worth a mention. The combined wave energy stays low, between 6 and 177 (weak to moderate), but it’s all poor-quality, chop-infested junk.
The only real standout – and I’m using the term loosely – comes on Wednesday morning the 12th of August. It’s not the swell size that’s the story, but the conditions. The wind goes completely glassy, dead calm, at Jupiter Inlet South Jetty (Florida). That’s a rare treat for the line-up. The swell is a tiny 0.3 ft from the northeast with a period of 9 seconds, so it’s a long-period groundswell, but there’s just no size to work with. The combined energy is a measly 7 (weak). You’ll be scratching for anything, but if you’re desperate for a paddle and some clean, glassy water, that’s your best shot. The water temperature is about average for this time of year.
For the rest of the period, there’s a little bump in the windswell around the 15th and 16th of August, but it’s all cross-onshore and choppy. The morning of Tuesday the 18th of August goes glassy again, but with a tiny 3 ft southeast windswell and a period of 5 seconds, it’s just weak and short. Nothing to get excited about.
Honestly, this is a proper flat spell. If you’re a beginner, at least there’s nothing dangerous. For the rest of us, it’s a time for longboard walks, fin tuning, or just looking at the horizon. Forecasts can change, but as it stands, there’s nothing worth rushing for.
Rusty.
