Table - best surf conditions forecast for Folly Beach over the next 16 days.
Alright, let’s talk Folly Beach, same story but in feet and miles per hour.
We’re looking at a flat start. For the first several days, the swell is tiny, just 0.7ft to 1ft at best, with short intervals. Wave energy is weak, barely registering. The wind does go glassy on Tuesday morning the 14th, which makes the surface look like a mirror, but there’s nothing to ride.
The first little bump comes Friday morning the 17th. You’ll see about 2ft from the SSW with a light cross-off breeze, 10 mph. It’s clean, but still weak. More of a longboard glide.
From Sunday the 19th, size picks up to around 4ft by the afternoon, but it arrives with a fresh 20–30 mph cross-onshore wind, making it lumpy and choppy. The swell direction is from the S to SSW, which isn’t ideal for Folly’s best exposure. Energy climbs to 88, so there’s some grunt, but the quality’s poor.
Your best shot is Tuesday morning the 21st. Swell is about 3ft from the SSW with a 15 mph cross-off breeze, so the surface is clean. Combined energy is moderate at 77. It’s not a pumping day, but it’s the cleanest you’re going to get with that much size. Expect some company, as crowds can show up sometimes.
Beyond that, the forecast goes back to small, poor surf with onshore wind most of the time. There’s a 4ft pulse on Wednesday afternoon the 22nd, but it’s lumpy and cross-onshore.
So, the pick of the week is that Tuesday morning the 21st. Clean, waist-high, and the most user-friendly of the lot. For beginners or anyone wanting an easy session, that’s the window.

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.
