The Lowdown
Alright folks, it's Rusty here. Gotta be straight with you – this 16-day outlook for the Folly Beach area is a bit of a tough one. Right off the bat, things are looking flat and poor. In fact, there's no real surf to recommend for a solid two weeks. The first good energy doesn't show up until late in the run.
Let's break it down. From August 11th right through to the morning of August 25th, we grinding through a long, flat spell. The combined wave energy is almost always below 100 – weak stuff. Most mornings we get a clean surface with light offshore winds, like that glassy NW wind on Saturday the 15th, but the swell is barely a ripple at 1 ft from the SE. It's enough to get wet, but you won't be catching much. The afternoons are worse, getting chopped up by moderate SSW breezes. It's a tough stretch for a paddle surfer. Honestly, if you're into it, some of those afternoons with the cross-onshore wind and bumpy conditions might be more interesting for a kite session.
Now, hang in there because things wake up on Tuesday the 25th. This is the one and true standout in the period. That Tuesday morning, we've got a pulse of swell – 4 ft from the East with an 8-second period. The wave energy bumps up to a solid moderate 159. It's blowing a fresh 19 mph NNE cross-offshore wind, which will keep the surface clean. 4 ft is getting into that territory where it's not for beginners, but for the rest of us, it'll be a fun morning. The wind will be howling, but it's offshore, and that makes all the difference.
After that, it drops off quickly. The swell hangs around into Tuesday afternoon at 4 ft, but the wind swings cross-shore and makes it lumpy. By Wednesday the 26th, the energy is fading fast back into the weak zone (61), and it's a lumpy cross-chop again.
So, the bottom line is this: get ready for a whole lot of nothing for the next two weeks. The water temperature on the 11th is sitting at 86°, which is a touch warmer than normal for this time of year, but it won't help the waves. The only real chance for a decent session is that Tuesday the 25th morning. Circle that date, keep your fingers crossed the forecast holds that far out, and be ready to go when that NNE wind kicks up.
Keep the faith,
Rusty
