Weather in South Carolina in March
March is the Goldilocks month for South Carolina. Winter's chill is gone but summer's brutal humidity hasn't arrived. Charleston averages 55-72°F with mostly sunny skies and the occasional afternoon shower that clears in 30 minutes. The coast is slightly cooler — Kiawah and Hilton Head run 52-68°F with a breeze off the Atlantic.
Inland at Congaree and the Midlands, temps push a bit higher during the day (58-75°F) and drop to the mid-40s at night. Rain averages 3-4 inches for the month, spread across 7-8 days — but these are quick passing showers, not all-day washouts. Pack a light rain jacket and you're covered.
- •March is the driest spring month in coastal SC. April and May bring more rain, so March gets you the bloom without the downpours.
- •Water temperatures hover around 58-62°F — too cold for casual swimming but fine for surfers in wetsuits at Folly Beach.
What to Pack
Layers are everything in March. Mornings start cool enough for a light sweater, afternoons warm to t-shirt weather, and evenings on the waterfront call for a jacket. Comfortable walking shoes are non-negotiable for Charleston's cobblestones. Bug spray for Congaree — the mosquitoes wake up in March. Sunscreen for beach days and garden walks.
Charleston in Bloom: Azaleas and Plantation Gardens
This is it. March is why people fly to Charleston in spring. The city's legendary plantation gardens hit peak azalea bloom, turning acres of landscape into walls of pink, purple, red, and white. The live oaks dripping Spanish moss provide the backdrop. Your camera roll will not survive.
- •Peak azalea bloom in Charleston typically runs from mid-March through early April. Plan for the last two weeks of March for the safest bet.
- •Magnolia Plantation on a Saturday in March is packed. Weekday mornings are a different planet — quiet, misty, and photogenic.
- •The Festival of Houses and Gardens (Historic Charleston Foundation) runs late March through April. Self-guided tours of private homes and gardens for $50-75. Book ahead.
Magnolia Plantation and Gardens
The crown jewel. Magnolia Plantation has been growing azaleas since the 1680s — 340+ years of garden refinement. March brings peak bloom across 70 acres of Romantic-style gardens, with over 900 varieties of camellias and azaleas. The boardwalk through the Audubon Swamp Garden is worth the extra $8.
Admission is $30 for adults (gardens only). The house tour adds $15, the garden boat tour adds $10. Go for the garden and swamp walk — the house is interesting but the gardens are the main event. Arrive at opening (9am) on weekdays for the lightest crowds.
| Category | Price Range |
|---|---|
| Garden admission | $30 adult |
| House tour add-on | $15 |
| Swamp Garden | $8 |
| Garden boat tour | $10 |
Middleton Place
America's oldest landscaped garden, designed in 1741. The terraced butterfly lakes and azalea hillsides are more structured than Magnolia's wild romanticism. Admission is $32 for adults. The stableyards with heritage breed animals give kids something to do while you photograph the reflecting pools. On-site restaurant serves Lowcountry lunch with ingredients from the property's garden.
Cypress Gardens
If you want the iconic South Carolina photo — the one with the flat-bottom boat gliding through a flooded cypress swamp with azaleas reflecting in black water — this is the place. Flat-bottom boat rides are included in the $10 admission. Yes, $10. It's Berkeley County's best-kept secret and a fraction of the price of the big plantations.
Kiawah Island: Early Beach Season
Kiawah Island in March is the move for people who want a beach vacation without the summer circus. Ten miles of pristine beach, mostly empty. Air temps in the mid-60s to low 70s. The Ocean Course — rated #1 public course in America by Golf Digest — is playable without melting. Resort rates are 30-40% below July prices.
The island's nature programs run year-round, with March bringing guided kayak tours through salt marshes ($65/person), birding walks along the beach ($25), and bike rentals ($12/hour) on 30+ miles of paved trails. Loggerhead sea turtles don't nest until May, but dolphins are active in the nearshore waters all month.
| Category | Price Range |
|---|---|
| The Sanctuary resort | $350-550/night (March) |
| Villa rentals | $200-400/night |
| Ocean Course green fees | $250-350/round |
| Kayak tour | $65/person |
| Beachwalker Park day pass | $10 |
| Bike rental | $12/hour |
Where to Stay on Kiawah
The Sanctuary at Kiawah Island Golf Resort is the flagship — a massive oceanfront hotel with spa, pool, and direct beach access. March rates run $350-550/night versus $600-900 in summer. Villa rentals through the resort or VRBO start at $200/night for a 1-bedroom with ocean view.
For budget-friendlier options, stay in nearby Johns Island or Folly Beach (20-30 minutes away) and day-trip to Kiawah. Beach access passes are $10/day for non-resort guests at Beachwalker Park on the west end.
The Ocean Course
Home of the 2012 and 2021 PGA Championships. Green fees in March run $250-350 per round — expensive, but about $100 less than peak summer rates. The course runs along 2.5 miles of oceanfront with salt marsh views on every hole. Wind is a factor year-round. Caddie recommended ($50 + tip).
Beaufort and the Lowcountry
Beaufort is what Charleston was 20 years ago — gorgeous, historic, walkable, and not yet overrun by bachelorette parties. The antebellum homes along Bay Street face the Intracoastal Waterway, and the town moves at the speed of a shrimp boat. March brings warm enough weather to actually enjoy the waterfront without the summer gnats.
The Lowcountry — the coastal plain stretching from Charleston through Beaufort to the Georgia border — is defined by its tidal creeks, salt marshes, and barrier islands. March is when everything turns green again. The spartina grass in the marshes goes from winter brown to vivid green, and the live oak canopies fully leaf out.
- •The Beaufort International Film Festival runs in late February/early March. If your dates overlap, grab tickets — small-town festival with surprisingly good films.
- •Shrimp season opens in late spring, but March restaurants serve frozen-fresh local shrimp that's still leagues better than chain restaurant fare. Try Plums on Bay Street.
Hunting Island State Park
South Carolina's most visited state park, 15 minutes from Beaufort. The beach is wild and undeveloped — no condos, no boardwalks. Climb the 167-step Hunting Island Lighthouse ($2) for panoramic views of the marsh and ocean. The maritime forest trails are shaded and flat. Camping is $25-40/night for tent and RV sites.
The north end of the beach has dramatic boneyard trees — dead oaks and pines toppled by erosion, bleached white by sun and salt. It's the most photographed spot on the South Carolina coast after Charleston.
Gullah Geechee Culture
The Lowcountry is the heartland of Gullah Geechee culture — the distinct African American heritage of the Sea Islands. St. Helena Island near Beaufort is a cultural center. Visit the Penn Center ($10), one of the first schools for freed slaves. Take a Gullah heritage tour ($35-50) to hear the language, taste the food (expect red rice, shrimp and grits, she-crab soup), and understand a culture that's been here since the 1600s.
Congaree National Park: The Forgotten Gem
South Carolina has a national park and almost nobody knows it. Congaree protects the largest intact expanse of old-growth bottomland hardwood forest in the southeastern United States. We're talking trees that were growing when the Constitution was signed. The canopy here is one of the tallest in the eastern US, with loblolly pines exceeding 160 feet.
March is ideal — the floodplain forest is green but the summer mosquitoes haven't reached full plague levels yet. The 2.4-mile Boardwalk Loop is accessible and flat, winding through the old-growth cypress and tupelo. Free admission. Yes, it's a national park with zero entrance fee.
- •Congaree is 20 minutes southeast of Columbia, the state capital. Easy day trip if you're driving between Charleston and the mountains.
- •Bring bug spray regardless of season. This is a swamp. The mosquitoes have their own zip code.
- •Ranger-led canoe tours on Cedar Creek are free but limited to 20 people. Sign up at the visitor center on arrival.
| Category | Price Range |
|---|---|
| Park admission | Free |
| Camping (primitive) | Free (backcountry permit required) |
| Ranger canoe tours | Free |
Best Hikes
The Boardwalk Loop (2.4 miles, flat) is the must-do and suitable for all fitness levels. For more, the Weston Lake Loop Trail (4.4 miles) takes you deeper into the floodplain with views of an oxbow lake. The River Trail (10 miles one-way) is for serious hikers who want to reach the Congaree River.
Check the flood gauge before visiting — when Cedar Creek floods (it happens several times a year), parts of the trail system go underwater. The boardwalk stays accessible in moderate floods, but ground-level trails can be impassable.
Synchronous Fireflies
Congaree is one of the few places in North America where synchronous fireflies put on a coordinated light show. The event happens in late May/early June, not March, but if you fall in love with Congaree on your March visit, mark your calendar and enter the lottery for firefly viewing spots. It sells out instantly.
Where to Eat and Stay
Lowcountry cuisine peaks in spring. She-crab soup appears on every menu from Charleston to Beaufort, shrimp and grits is religion, and the oyster roast season extends through March before the warm months bring harvesting closures. Expect to eat very well for not a lot of money.
| Category | Price Range |
|---|---|
| Charleston boutique hotel | $200-400/night |
| Mount Pleasant motel | $100-150/night |
| Beaufort B&B | $150-250/night |
| Husk dinner entree | $30-50 |
| Rodney Scott's BBQ plate | $14-18 |
| Casual dinner per person | $20-35 |
Charleston Dining
Husk (Sean Brock's landmark) remains the reservation to chase — Southern ingredients, no exceptions, $30-50 entrees. FIG on Meeting Street is more approachable and equally excellent. For casual, hit Rodney Scott's BBQ on King Street for whole-hog barbecue that won a James Beard Award. The brisket line moves fast.
Upper King Street has become Charleston's restaurant row. Walk it on a Friday night and you'll pass 30 places worth eating at. Budget $20-35 per person for a sit-down dinner without drinks; add $15-25 for cocktails.
Where to Stay in Charleston
The Historic District puts you within walking distance of everything but commands a premium — $200-400/night at boutique hotels like The Spectator or Hotel Bennett. The Restoration on King Street is a solid mid-range pick at $180-280/night. For budget, look at motels on the Mount Pleasant side of the Ravenel Bridge — $100-150/night with a 10-minute drive downtown.
Beaufort Stays
The Anchorage 1770 is a boutique inn right on the waterfront ($180-300/night). City Loft Hotel offers modern rooms from $130-200/night. B&Bs in the historic district run $150-250/night and include breakfast that's actually worth waking up for.
