Stand-up paddleboarding is a different game from kayaking or a boat ride. You’re upright, fully exposed, and sooner or later you’re going in the water. If you’re new to what stand-up paddleboarding is, the short version is this: plan your outfit for swimming, not for a stroll on the dock.
Dress for the water, not the air. The tea-colored water in the harbor runs cold in winter and warm by June, and what you’re wearing when you fall in matters more than how you look paddling out.
Start with What You’d Swim In
The base layer is simple. Wear what you’d wear in the ocean:
- Board shorts or a swimsuit, anything quick-dry and synthetic. It dries fast when you’re back on the board, and it won’t drag you down when you’re in the water.
- A rash guard, optional in summer but useful if you burn easily or plan to be out more than an hour. A short-sleeve or long-sleeve UPF top covers you without adding much warmth.
- No cotton. A cotton shirt gets heavy when wet and clings uncomfortably. Leave it for the drive home.
Summer vs. Winter
Charleston’s seasons change what the base layer actually means.
Summer, roughly June through September: the air is hot and the water is warm. A swimsuit or board shorts plus a rash guard is plenty. The bigger concern is the sun, not the temperature.
Winter and shoulder seasons: the water in Charleston Harbor and the Lowcountry waterways gets genuinely cold, dropping into the 50s. If you fall in, cold water takes the breath out of you fast. Add a wetsuit or neoprene layers, and consider neoprene booties. A 2mm to 3mm full wetsuit is a reasonable investment if you paddle from November through March.
Sun Protection Comes First
You’re standing on an open board with nothing overhead. The reflection off the water adds to the exposure from above. Even on a partly cloudy day, an hour on the water without protection will burn you.
- A hat with a brim, ideally with a chin strap so it stays on when the wind picks up.
- Sunglasses with a retainer strap, since polarized lenses cut the glare off the water and a strap keeps them on your face when you fall, not on the bottom of the creek.
- Sunscreen on every exposed surface. Reapply if you’re out longer than 90 minutes, because sweat and water strip it.
- A UPF long-sleeve rash guard doubles as both sun protection and minor warmth on cooler mornings.
The afternoon thunderstorm season in summer (June to September) adds another thing to plan around. Check the forecast before you launch. A storm building to the west is not something you want to be standing on an open board for.
Safety Gear You Actually Wear
Before you get to optional accessories, two things aren’t optional:
A leash. It connects your ankle to the board. When you fall, the board stays with you instead of drifting 50 yards downwind. On a tidal waterway with any current at all, an unleashed board moves faster than you can swim. Check what to know before your first SUP session for more on reading the current before you launch.
A personal flotation device (PFD). A life jacket is required by law on the water. The practical solution is an inflatable belt-pack PFD, which sits around your waist and doesn’t interfere with paddling at all. It doesn’t look like a bulky life jacket, and it deploys fast if you need it. You can compare inflatable belt-pack PFDs on Amazon to see the options.

Footwear
Many paddlers go barefoot on the board, which is fine once you’re on the water. The issue is getting there.
Charleston’s launches often cross oyster beds or cut through marsh edges. Oyster shells are sharp and will cut through the soles of your feet without warning. Water shoes with a rubber sole solve this. They’re lightweight, drain fast, and you can paddle in them or slip them off once you’re clear of the bank.
What to Bring (and How to Carry It)
Even a short session needs a few things you don’t want to get wet:
- A dry bag for your phone, keys, and any cards. Clip it to the board or wear it as a waist pack. A zip-lock bag works in a pinch, but a proper dry bag is more reliable.
- Water. You’re standing in the sun for an hour or more. Bring more than you think you need.
- A dry change of clothes in the car. You will be wet at the end.
Finding the right spot to launch also matters for what you’ll need on your feet. The places to paddleboard around Charleston vary from sandy boat ramps to grassy banks to oyster-edged creek access, so footwear that works at one spot may matter more at another.
FAQ
Do I need a wetsuit for summer SUP in Charleston?
Not in peak summer. Water temperatures in July and August are warm enough that a swimsuit is fine. A wetsuit becomes useful from November through March when the water gets cold enough to be a risk if you fall in.
Can I wear regular sunglasses on the water?
You can, but they’ll sink if they come off. A retainer strap costs a few dollars and keeps them on your face. Polarized lenses are worth the upgrade for cutting the glare off the water.
Is a life jacket required for SUP?
Yes. Under South Carolina law, you need a Coast Guard-approved PFD on the water. A belt-pack inflatable PFD is the practical choice for stand-up paddleboarding since it doesn’t restrict movement.
What if I’m only going out for 30 minutes?
Same rules apply. Sun and current don’t care how long you planned to be out. Leash, PFD, sun protection, no cotton. That’s the short list.
