The Lowdown
Alright folks, Rusty here. Let me be straight with you: right now, we’ve got a real flat spell on the cards for Folly Beach (Folly Beach). The finder is showing zero good surf options across the entire 16-day window, and every single session is flagged as “poor surf conditions.” There’s not a single standout day to get excited about. The forecast is basically a long stretch of tiny, wind-affected slop.
The water is sitting at 87° – that’s much warmer than usual for this time of year, so at least the paddle will be pleasant.
We start Thursday the 20th with tiny 1 ft swell from the SE, period a weak 8 seconds, and a light cross-shore breeze. The combined energy is a measly 11 – barely a ripple. Friday the 21st is even worse, with 0.7 ft swell and a choppy cross-onshore wind. Saturday the 22nd morning cleans up with a light cross-off breeze, but the swell is still only 0.7 ft. By Saturday afternoon, a short-period 2 ft S swell rolls in but with a moderate cross-onshore, making it choppy. Sunday the 23rd offers the best-looking wind of the first week – clean cross-off breezes in the morning and afternoon – but the swell is just 2 ft of short-period windswell, and combined energy only reaches 36. That’s not enough to get you up and riding.
From Monday the 24th through the end of the month, we see a mix of tiny swells (0.7 ft to 3 ft) and mostly cross-onshore or cross winds. The highest combined energy in the whole run is 70 on the morning of Friday the 28th, with a 3 ft SSW swell and clean cross-off wind, but it’s still a short-period, weak swell that won’t produce any real shape. Winds stay light and clean at times, especially on the 29th and 30th mornings when it’s glassy, but the swell is only 1 ft.
The first week of September doesn’t look any better. The first few days of September serve up more of the same: tiny swells, cross-onshore winds, and poor conditions. The 3rd of September morning sees a 2 ft E swell with a 7-second period, and combined energy climbs to 59 – still not enough to call it surfable.
The takeaway is simple: there’s nothing on offer for the next 16 days at Folly Beach. The breaks are inconsistent, the swell is weak, and the wind is rarely on our side. For a spot that’s fairly exposed, it’s a frustrating run. If you’re desperate to get wet, you might find a tiny, clean bump on the glassy mornings, but don’t expect to catch anything with any push. For paddle surfing, it’s a bust. The setup looks more interesting for kite surfing than paddle surfing on those days with a bit more wind.
Hang in there, check back – forecasts can change.

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.
