The Lowdown
Alright folks, Rusty here. Let's have a look at what we've got coming up for Folly Beach.
To be straight with you, the next 16 days are a tough stretch. We’re looking at a long gap with hardly a wave worth paddling for. The whole period is filled with small, weak surf and the occasional onshore wind making a mess of things. It kicks off with nothing rideable and it’s going to be a long wait. The first few days look pretty flat, and honestly, it stays that way for the bulk of the forecast. There’s a lot of days there where you’d be better off doing something else.
The water temp is sitting at a warm 85°F, about 3°F warmer than usual for this time of year, so you can get away with a shorty or just boardies.
We don’t really get a standout session, but if you’re desperate, a couple of mornings *might* offer something clean, but the swell will be tiny.
Let’s run through it. From the start, Monday the 24th has a tiny 2ft of weak, short-period S swell with a cross-on wind. It’s choppy and not worth your time. Tuesday morning the 25th is cleaner with a light cross-off breeze, but the swell drops to a pathetic 0.7ft. That pattern of ankle-bite waves and mixed wind holds through until the end of August.
There’s a glimmer on the morning of Monday the 31st. It’s glassy, with a light offshore wind, and we see a slight bump to 2ft from the SE with a period of 7 seconds. The combined energy is still weak (41), so it’s a really small, slow day, but it’ll be the cleanest surf you’re likely to see all week. The water will be smooth, so if you have a longboard or a foiling setup, you might find a dribbly one.
Moving into September, early on Tuesday the 1st, we see a long-period groundswell of 1ft from the SE with a period of 16 seconds. That's a very long period for a tiny wave, which means long waits between sets and it might break too straight for Folly’s beach break, but we do get clean conditions with a cross-off wind. The energy is still low (55). Wednesday the 2nd morning is similar with a clean cross-shore and 1ft, but the period drops to 13 seconds.
The next real notable, and probably the “best” of a bad bunch, is later on. Friday morning, September the 4th, sees a slightly bigger pulse. We’re looking at 2ft from the ESE with a 13-second period. The combined energy finally breaks into the moderate range at (123). The wind is a moderate cross-shore, so it won’t be perfect, but that’s the biggest, most powerful swell in the whole outlook. It's not big by any standard, but it's the only time we get some real energy in the water.
After that, it fades back into tiny, weak windswell again. The weekend of the 6th and 7th has small 2ft to 3ft stuff from the E and ENE, but it’s all onshore and messy. The period drops short, and the energy is weak again.
So, there you have it, folks. A long flat spell with a couple of clean but tiny windows, and only one morning where the energy picks up to a mediocre level. This is a tough one for Folly. The board stays in the van for a while.
That's it from me.
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.
