South Carolina Nature Guide: August 2026
August is late, hot summer in South Carolina, with the first stirrings of fall migration — shorebirds and Swallow-tailed Kites stage along the coast, hummingbird numbers swell, the markets stay rich with peaches, tomatoes, and shrimp, and the Perseid meteors streak the warm August nights. Hurricane season runs in the background.
What to look for this week
- Tundra Swans and rafts of ducks crowd the ACE Basin impoundments at their winter peak, while Lowcountry Christmas Bird Counts wrap up across the state.
- The Quadrantid meteor shower peaks in a short, sharp burst around January 3 — best after midnight from a dark Upstate ridge at Caesars Head or the unlit ACE Basin marshes.
- A planning week in the cold Upstate, but Lowcountry cold frames keep collards and kale growing — order seeds early before favorites sell out.
Birds This Month
August brings the first real wave of fall movement to South Carolina even as summer holds. Southbound shorebird migration is in full swing on the coast — Short-billed Dowitchers, yellowlegs, Semipalmated, Western, and Least Sandpipers, plovers, and Whimbrel crowd the mudflats and impoundments at Huntington Beach State Park, Bear Island, and the ACE Basin. Post-breeding wading birds concentrate spectacularly — Wood Storks, Roseate Spoonbills, White Ibis, herons, and egrets gather in the drawn-down impoundments.
One of the month's highlights is the pre-migration gathering of Swallow-tailed Kites, which form communal roosts of dozens to hundreds over the Lowcountry river swamps before their journey to South America. Purple Martins stage in huge roosts, and Ruby-throated Hummingbirds swell in number as northern birds pass through and locals fatten for migration — fill the feeders now. Common Nighthawks begin their evening flights overhead late in the month, and the first songbird migrants — warblers, vireos, and flycatchers — start trickling through the woods.
What's Blooming
August's bloom in South Carolina is the rich late-summer flora that fuels the migration. The Piedmont and Sandhills old fields and roadsides glow with the first goldenrod, ironweed, Joe-Pye weed, blazing star (Liatris), partridge pea, mistflower, and the lingering black-eyed Susan and coneflower. The climbing passionflower (maypop) and red trumpet creeper still flower along the fences.
In wet ground, cardinal flower flames scarlet along stream banks and swamp edges, worked by hummingbirds, with swamp milkweed, lizard's tail, swamp sunflower, and buttonbush on the water. The longleaf savannas hold late meadowbeauty and orchids. Along the coast, the sweetgrass begins to plume toward its fall silvering, the salt marshes show the first hints of sea oxeye and saltmarsh aster, and gardens blaze with crape myrtle, lantana, zinnia, salvia, and the beautyberry turning toward its brilliant purple fruit. The first autumn asters appear late in the month.
Garden This Month
August is the pivot from summer harvest to the fall garden in South Carolina. The summer crops keep coming — pick okra, peppers, eggplant, southern peas, butterbeans, the last tomatoes, melons, and sweet potatoes as the season winds down — while the heat-and-humidity pressure stays high. Many spring tomatoes are spent and ready to pull, though a second fall tomato crop set out earlier is sizing up.
This is prime fall-planting time, especially the second half of the month. Direct-sow turnips, beets, carrots, radishes, fall bush beans, and a final round of squash and cucumbers, and set out transplants of broccoli, cabbage, cauliflower, collards, kale, and Brussels sprouts for the fall and winter garden — South Carolina's long, mild fall rewards it well. Water new plantings carefully through the heat, provide afternoon shade for tender seedlings, and stay ahead of fall armyworms, stink bugs, and the persistent humidity diseases. Refresh mulch, pull spent crops, and prepare beds for the cool-season planting ahead.
Zone 7b (Upstate & foothills): the fall window opens. Set out fall broccoli, cabbage, collards, and kale transplants, direct-sow turnips, beets, carrots, and a fall planting of bush beans, and keep watering the fading summer crops.
Zone 8a (Midlands & Sandhills): prime fall planting. Sow fall greens, turnips, carrots, and beets, set out broccoli, cabbage, and collard transplants, plant a fall crop of squash and beans, and keep harvesting okra and peppers.
Zone 8b (lower Coastal Plain & Lowcountry): the long fall season begins. Start the cool-season transplants under shade, direct-sow fall greens, and plant a second crop of squash, cucumbers, and beans for a generous Lowcountry fall harvest.
What's at the Farmers Market
August keeps South Carolina markets richly abundant. Peaches continue from the Ridge and Pee Dee orchards into the month — the late varieties among the sweetest of the year — alongside watermelon, cantaloupe, muscadines and scuppernongs beginning, and the first figs. The vegetable tables stay full of tomatoes, okra, peppers, eggplant, butterbeans, southern peas, sweet corn, squash, cucumbers, and field peas.
On the coast, Lowcountry shrimp is at its peak, plump and abundant. Boiled-peanut stands, cut flowers, herbs, and local honey round out the markets in Charleston, Columbia, Greenville, Beaufort, and the Pee Dee. Choose peaches by fragrance and ripen firm fruit on the counter. Pick tomatoes heavy and fragrant, kept at room temperature. Choose a watermelon heavy with a creamy ground spot, pick okra small and tender, and select figs that are soft and fully colored — they don't ripen further off the tree, so use them quickly. Buy shrimp firm and translucent and keep it well iced.
Night Sky This Month
August offers one of South Carolina's best night-sky events of the year — the Perseid meteor shower, which peaks around August 12, one of the most reliable and prolific showers, sending bright meteors and fireballs across the sky after midnight. Head to a dark site for the best show: the Upstate's Caesars Head and Table Rock State Park, the ACE Basin marshes, or the unlit beaches at Huntington Beach State Park, where astronomy clubs often hold a Perseid watch.
The summer Milky Way still arches high across the sky, its glowing core in Sagittarius and Scorpius rich with star clouds, nebulae, and globular clusters for binoculars and telescopes. The Summer Triangle of Vega, Deneb, and Altair rides nearly overhead, and the Andromeda Galaxy begins to climb in the northeast late in the night, a faint smudge to the naked eye from dark skies. The printable South Carolina night-sky guide gives this year's exact Perseid peak timing, planet positions, and the best dark-sky locations.
Butterflies & Pollinators
August keeps South Carolina's butterfly numbers high as the late-summer broods build toward fall. The swallowtails remain numerous — eastern tiger, zebra, spicebush, black, giant, and the coastal palamedes — alongside abundant gulf fritillaries, cloudless and sleepy sulphurs, common buckeyes, red-spotted purples, viceroys, American and painted ladies, and clouds of skippers on the late flowers.
The monarch's final summer brood begins to give rise to the migratory generation that will fly south. Cloudless sulphurs reach big numbers and stream southward late in the month, and long-tailed and silver-spotted skippers, and the southern fiery and ocola skippers, work the gardens. In the coastal Lowcountry, look for southern strays like the little metalmark and the increasing gulf fritillary. Watch the blooming lantana, zinnia, ironweed, and Joe-Pye weed for nectaring butterflies, and check milkweed and passionflower for caterpillars. Keep nectar flowers blooming and water available — the late-summer garden is one of the best butterfly stops of the year.
Trees This Month
August holds South Carolina's forests in full, slightly tired late-summer leaf, with the summer-flowering trees finishing. The crape myrtle still blazes across the towns and roadsides, and the chaste tree and late magnolia show scattered blooms. The native devil's walkingstick lifts its great white flower clusters at woodland edges, and the black gum (tupelo) shows its very first early-turning scarlet leaves — among the earliest hints of fall.
The fruits ripen across the canopy. The acorns swell and begin to drop from the oaks, the black gum and devil's walkingstick set blue-black fruit for migrating birds, the native beautyberry turns brilliant purple, and the cabbage palmetto (the state tree) ripens its small black drupes along the coast. The live oaks, southern magnolia, cabbage palmetto, and wax myrtle hold their evergreen Lowcountry green, and the bald cypress still stands richly green in the swamps. The pines hold their full crowns. The forest is preparing, quietly, for the coming turn of the Southern fall.
