The Lowdown
Right now, the ocean’s flat as a pancake out here, and honestly, it’s looking pretty bleak for the next week and a half. We’re talking tiny, wind-chopped slop with almost no push behind it. The swell energy is weak, sitting in the low-to-mid 50s (52) at best on Wednesday morning, and it just fades from there. You’d be fighting an onshore breeze for nothing.
That run of nothing stretches from now through the 27th. Days of ankle-biters, with the odd pulse of knee-high mush. The winds are mostly cross or cross-on, keeping things bumpy. It’s the kind of stretch where you check the cam and immediately think, “nah, not worth the drive.”
Then, on Monday the 28th, things finally wake up a touch. The morning brings a bit more size, pushing to around 4.3ft, with moderate energy (251). Still, the wind is on it, so it’s not going to be pretty—more of a messy, lumpy option than a clean one. The period is only 8-9 seconds, so it’s short-period windswell, not the good stuff.
The real standout window is the 29th into the 30th. Tuesday afternoon gets a funky bump, with swell jumping to 6.6ft and energy spiking hard (911), but that’s a bit of a junky, powerful swell with an onshore flow. Not for the faint-hearted. Then Wednesday morning is your best bet overall. The swell drops back to a more manageable 2.6ft but the period jumps to 13 seconds (377), and we get a cross-offshore breeze. That combination—cleaner water, long-period groundswell—will actually shape up nicely at breaks that can handle that kind of swell. That’s your standout, but it’s a one-morning deal before the wind swings onshore again.
For context, the water temp is pretty much average for this time of year, nothing crazy there.
So, if you’re keen, pencil in Wednesday the 30th. You’ll want a spot that handles a longer period, because a 13-second swell at a beach break like this can run a bit straight. It’s not a classic, but it’s the best we’ve got on the board.

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.
