The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one. We’re looking at a solid 16-day window, but honestly, it’s a real flat spell for Folly Beach. There’s nothing on the table that I’d call a proper surf session. The first few days are a total write-off, and that sets the tone. We’ve got a long stretch of poor conditions with hardly any energy.
For the first week, from Sunday the 6th right through to the end of the week, it’s a no-go. We’re talking tiny, weak swell with cross and cross-onshore winds messing everything up. The combined energy barely gets going, with values like 10 (weak) on Sunday morning, and even when it climbs to 204 (moderate) by Tuesday afternoon the 8th, the wind is fresh and onshore, so it’s lumpy and choppy. The water temperature is sitting at a touch warmer than normal for this time of year, about 84°, but that’s the only positive.
We get a few mornings with clean conditions due to light offshore or cross-off winds, like on Sunday the 13th and Tuesday the 15th, but the swell is still tiny – only 2ft and 1ft. The period is short, around 4 to 9 seconds, so there’s no push or power. It’s just not worth paddling out for.
The second week is more of the same. We see a few mornings with clean conditions, like Thursday the 17th and Friday the 18th, but the swell is practically non-existent – 2ft and 0.3ft. The period jumps up to 13 seconds on the 17th and 18th, suggesting a long-period groundswell, but there’s almost no height behind it. It’s a tease. By the end of the window, on Monday the 21st, the wind is howling at 22-25 mph from the NE, making it messy.
So, what’s the best on offer? Honestly, there isn’t one. If you absolutely had to pick a moment, the cleanest conditions might be on the morning of Sunday the 13th, with light cross-off wind and 2ft of S swell at 4 seconds, but it’s weak and short. That’s about as good as it gets, and that’s saying nothing.
It’s a bleak outlook for paddle surfing. The conditions are so poor for so long that, frankly, if you see any bump in the water, it might be more interesting for kite surfing than trying to catch a wave on a log. Folly Beach (United States) just isn’t delivering this time.
Keep an eye on it though – these flat spells don’t last forever.
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.
