The Lowdown
Alright folks, Rusty here again.
Let’s be real – Folly Beach is in a flat spell for a good while. From the 15th through the 25th of July, it’s mostly tiny, choppy, onshore junk. You’re looking at swell heights under 2 ft for days, with weak combined energy in the low double digits (9 to 19). The wind’s all cross or cross-onshore. There is literally no surfable recommendation in that whole stretch.
The water’s about 85°F, which is a touch warmer than normal – feels like a bathtub, but not a wave pool.
Finally, on the morning of Sunday, July 26th, things turn. We get a 4 ft SSW swell, with a clean cross-offshore breeze from the west. The combined energy jumps to 125 (moderate). That’s the first real chance to get wet. The period is short at 6 seconds, so it won’t be a classic groundswell – a bit bouncy – but it’s a wave you can actually ride.
Then the morning of Tuesday, July 28th offers another 3 ft SSW swell with clean offshore wind and energy at 80. A solid backup.
Also, look at the mornings of July 30th – we get glassy conditions with a 3 to 3 ft SSW swell. Zero wind, smooth as a mirror. That’s a quiet, clean session for the patient surfer, likely with no crowds.
For a beginner-friendly beach like Folly, those 3-4 ft clean days are perfect. The crowds are *sometimes* a factor, but there’s plenty of beach to spread out. Don’t bother with the first ten days. Your window is July 26th, 28th, and the glassy 30th. That’s it.
Rusty.

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.
