The Lowdown
Alright, let's get into it. Rusty here, and I'll tell you straight – the next two weeks are a tough watch for Folly Beach. We've got a long stretch of flat, weak, and messy conditions ahead where nothing really comes together.
We're starting off with no real surf to speak of. Thursday kicks things off with barely a push. The water temp is sitting at 83°, which is about a degree and a half warmer than usual for this time of year, so a little bit of that summer warmth is hanging on, but that’s where the good news ends. The swell energy is tiny, barely registering a 36 on the energy scale. It's weak, and it's not going anywhere.
From here, it's a long stretch of poor conditions. We'll see a few days where the wind lightens up and the water gets clean, like Saturday morning and Sunday morning, but the swell is just too small – 1 ft to 1 ft – to even get excited about. The period is short and the energy is barely there. This is a real dry spell. We're looking at a gap of nearly a week and a half of nothing worth paddling out for.
Now, the only time things start to show a pulse is around Saturday the 19th and Sunday the 20th. The swell finally bumps up a bit, with Saturday morning seeing a clean 3 ft from the E with a 7-second period and 70 units of energy. Not big, but the cross-offshore wind from the NNE keeps it clean. That energy climbs to 117 on Saturday afternoon as the swell hits 3 ft, but the wind swings onshore and chops it up. By Sunday, a fresh breeze from the ENE at 19 mph has the waves lumpy and messy. It's a tease.
The best shot in this whole forecast is Wednesday the 23rd. We finally get a decent combination. The morning starts with a clean 4 ft swell from the E, with a period of 8 seconds and moderate energy of 149. But the key here is the wind: a strong 22 mph offshore from the W. That's going to clean it right up and hold the faces open. It'll be a bit of a battle to get out, but the reward will be some fun, punchy walls on the sets. By the afternoon, it drops back to 3 ft but stays clean with a lighter WSW breeze. This is the standout window, plain and simple.
Overall, there's a lot of waiting for a short window. For the beginner to intermediate crew, that swell on the 23rd is manageable, but the offshore wind makes it a bit trickier. For experts, it's a welcome break from the flat spell. If you're itching for a paddle, that Wednesday morning is your only real call. For everything else, save the drive.

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.
