The Lowdown
Alright folks, Rusty here. Let's be straight with you: if you're looking for a proper surf this next couple of weeks, Folly Beach is not the place to be. The whole 16-day window is pretty much a write-off. We've got a long, flat stretch from now through to mid-September, with nothing but tiny, weak dribble that's barely worth paddling for. There's a bit of a bump in the energy towards the end of the window, but the wind is going to absolutely trash it. This is one of those periods where you're better off finding something else to do.
From today, Thursday the 10th, right through to Saturday the 19th of September, the swell is puny, mostly below 2ft, and the wind is rarely your friend. You'll see some glassy mornings – like Monday the 14th and Tuesday the 15th – but even then, the waves are just knee-high dribble with a combined energy from 12 to 30 (weak energy). It's clean, sure, but there's nothing to ride.
The only real pulse of energy shows up on the 19th and 20th. On Saturday morning the 19th, we get a clean 3ft swell from the ENE, but it's a short period of 6 seconds, so it'll be weak and crumbly. The energy is a moderate 56. The real kicker is the wind – on that Sunday the 20th, it's howling out of the ENE at 22 mph, and the same for Monday the 21st. That's cross-shore and lumpy, making a mess of the 3ft to 3ft swell. The combined energy gets up to 99 (weak energy) on Monday afternoon, but with that wind, forget it. That's more of a kite surfing deal than a paddle surf session.
The biggest swell we see is towards the end, on Wednesday the 24th and Thursday the 25th of September. The 24th brings a 6ft east swell with a combined energy of 635 (moderate wave energy). But again, the wind is a strong cross-onshore, so it's going to be choppy and blown out. Then on Friday the 25th, we have 6ft from the east with a whopping 680 energy (moderate wave energy). That's the biggest of the bunch, but the wind is still a messy onshore breeze. For the experienced crew, there might be a few makeable ones in there if you can handle the chop, but for the average surfer, this whole period is a big miss.
There are no standout days here. Nothing to get excited about. The waves just aren't cooperating.
Rusty.

Information about the Folly Beach Surf forecast
The above surf forecast table for Folly Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Folly Beach can be found by selecting the local surf guide option on the grey menu. Our Folly Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Folly Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Folly Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
