The Lowdown
Alright, folks. Rusty here. Let’s be straight with you – this is a tough one for Folly Beach. We’ve got a 16-day window ahead, but don’t go getting your hopes up. The models are showing next to nothing worth paddling out for. The water’s sitting at a warm 86°, which is a touch warmer than normal for this time of year, but that’s about the only good news.
Right from the start on Monday, August 10th, it’s a no-go. We’re looking at a tiny 2ft swell from the south with a short, weak 4-second period – that’s just wind bump. The combined swell energy is a measly 20, and with a cross-on breeze from the south, it’s choppy and messy. That’s the story for the whole first week, really. You’ll see glassy mornings on a few days, like Friday the 14th and Saturday the 15th, but the swell is practically non-existent – 0.3ft and 1ft with barely any energy (2 to 8). There’s nothing to surf.
We roll into the second week, and it’s more of the same. The morning of Tuesday, August 18th, shows a long-period groundswell from the ESE at 15 seconds, but it’s only 0.7ft. That’s a tease. There’s a bit of a bump on Wednesday the 19th afternoon, with a 3ft swell from the ESE and the combined energy finally hitting 217 – that’s moderate energy. But the wind is a cross-on mess at 25 km/h, making it choppy and poor. For a beach break like Folly, that kind of period and onshore wind is just a washing machine. Honestly, it’s looking more interesting for kite surfing than paddle surfing on those days.
The few glassy mornings we do get, like Friday the 21st and Saturday the 22nd, are accompanied by knee-high dribble – 1ft and 2ft – with no push. The combined energy on those is still weak (34 and 36). There’s just nothing to get excited about. The entire 16-day run is a blank. For Folly, that’s a bit of a bummer, but it happens. The crowd is sometimes a factor here, but with no surf, the only people on the beach will be the sandpipers.
Stay patient, keep an eye on the forecasts, and I’ll be back when it’s worth charging.

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.
