The Lowdown
Alright folks, this is Rusty. Let's be honest, this stretch is a bummer for waves. Let's get into it.
Right now, the water’s a warm 84° – a touch warmer than normal for this time of year, so you’re looking at board shorts territory. The problem is, the waves just aren't there. For the next several days, Folly Beach Pier is giving us next to nothing. We're looking at tiny, short-period slop from the ESE at barely 0.7ft to 1ft, with a side-shore breeze ruining any chance of a clean face. Wave energy is in the single digits and low teens (9 to 18) – that's basically zero power. For the whole weekend and into the start of the week, the scores are all zeros. It’s flat, choppy, and a waste of time.
Mid-week on the 23rd of July, things finally clean up a little with a cross-offshore breeze. Swell size bumps to about 3ft from the SSW, period is short at 6 seconds, and the energy hits a moderate 84. It’s not pumping, but it will be the cleanest we’ve seen. Thursday the 24th stays glassy but drops back to 3ft. Still poor quality, but you can at least see the water.
Another potential window is the morning of Tuesday the 28th of July when we finally get a glassy, dead-calm morning with a light wind. We'll have 2ft of S swell, but the energy is weak (38) and period is short (5 seconds). Great conditions, terrible waves. If you really need to get wet on a longboard in knee-high mush, that’s your spot.
The only true standout in the whole 16 days comes on the morning of Thursday the 30th of July. We see a bump to 4ft of S swell with a clean, cross-offshore breeze. The combined energy reaches 93 – the highest reading of the entire forecast. The period is still short at 6 seconds, so it’s not a groundswell, but this will be the biggest and cleanest stuff we see. After that, it all flatlines again into August. This is the reality of summer on Folly; it can be inconsistent for long stretches. Stay tuned.
Rusty.
