The Lowdown
Alright folks, Rusty here. Let's have a look at what Folly Beach has cookin' over the next couple of weeks.
Honestly, it’s a bit of a flat spell for us on Folly for the next week and a half. We've got a long stretch starting from Tuesday the 15th all the way through to the 28th where the ocean just isn't showing much love. Tiny, weak, and messy is the name of the game for the bulk of that time, so don’t bother paddling out unless you want a nice float. The wind is mostly cross or cross-onshore, keeping things choppy and lumpy. We're talking combined energy values hanging in the paltry range (8 to 89), so the ocean is just sleeping.
Now, there is a little flicker of life right at the very end of the window. On the morning of Tuesday the 29th of September, the charts are lighting up. We’ve got a combined energy value of 430 (moderate wave energy) rolling in, a noticeable jump. The summary swell height is 5 ft from the ENE with a moderate 7-second period. That’s a bit of a beefy, short-period windswell—nothing too clean—but the real key here is the wind. It’s showing glassy conditions. Absolutely perfect, clean, no-ripple conditions for that dawn session. For a spot like Folly Beach, that early morning glass before the seabreeze kicks in is pure gold. That’s your one true standout, but you have to wait for it. Wednesday the 30th also cleans up nicely with a cross-offshore breeze from the N, but the swell drops fast.
Before that little burst, keep an eye on the morning of Monday the 21st of September. The swell is tiny at only 1 ft, but it's glassy again. It might not have the push for a proper wave, but if you’ve got a longboard and just want the place to yourself, that's your only other chance for absolutely clean conditions. Crowds are *sometimes* an issue here, but on a flat, glassy morning in September, you'll likely have the place to yourself.
So, the story is: wait it out. Save the wax for the 29th, set the alarm, and prepare for a great glassy session on some moderate-sized ENE swell. Everything else is a skip.

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.
Folly Beach is 8 km (5 miles) from the city of Mount Pleasant. If you plan a vacation in South Carolina, look for hotels and other accommodation in Mount Pleasant. Mount Pleasant has rooms for a wide range of budgets as well as car hire and transport links.
