What to look for in nature in South Carolina this October

When do the leaves turn in the South Carolina mountains?

• The escarpment parks

  Usually late October into early November; possibly earlier and duller this year · Table Rock, Caesars Head, Jones Gap, Keowee-Toxaway, Devils Fork and Oconee state parks

  These are the parks South Carolina State Parks lists first for foliage, and they sit where the mountains drop abruptly onto the Piedmont, so a single overlook shows several elevations turning at different speeds. At Caesars Head, Raven Cliff Falls, a 420-foot cascade, is a 6.6-mile round trip. Their weekly foliage reports are the best way to time a drive this year.

• Sassafras Mountain, first to turn

  Usually the earliest color in the state · Pickens County, on the North Carolina line

  At 3,553 feet, Sassafras is the highest point in South Carolina, and its summit platform, finished in 2019, looks out in every direction. Its ridgetop hardwoods tend to turn before the valleys do. The platform doubles as a hawk-watch station, so bring binoculars for both jobs.

• Piedmont and Midlands woods

  Mostly November · Sweetgum, hickory, dogwood and red maple along creeks and fencerows

  Below the mountains the season slides later. Dogwoods and sourwoods redden first, sweetgums follow in a mix of purple, red and yellow on the same tree, and the hickories go gold. In the Congaree floodplain the bald cypresses turn a rusty orange later still, usually well into November.

Where can you watch hawks and falcons migrate over South Carolina?

• Late broad-wings, then the October mix

  First days of October for broad-wings; all month for the rest · Caesars Head overlook and Sassafras Mountain, best 10 a.m. to 5 p.m.

  A few late kettles of broad-wings can still pass in the first week. After that the flight turns to sharp-shinned and Cooper’s hawks, red-tails, kestrels, the odd peregrine or osprey, and turkey vultures, which average more than 900 a season at Caesars Head and more than 3,200 at Sassafras. The good days follow a cold front, when a northwest wind strikes the escarpment and lifts the birds. Volunteers keep the tally; ask them what has been moving.

• Falcons on the coast

  Early to mid-October is the classic peregrine window · Botany Bay Plantation WMA, Edisto Island

  The Edisto count is a different animal. Its averages run to about 10,500 turkey vultures, 253 American kestrels and 68 peregrine falcons per season, the peregrines racing south along the beach from the Arctic. Botany Bay is a wildlife management area, so check hunt-day closures before you go.

• Oystercatchers gathering at Cape Romain

  Fall into winter · Cape Romain National Wildlife Refuge, Awendaw and McClellanville

  The refuge’s 22 miles of islands and marsh hold the largest wintering population of American oystercatchers on the Atlantic and Gulf coasts, and the flocks build as the season turns. The islands are reached only by boat, from Garris Landing or on the concession ferry to Bulls Island; the Sewee Visitor Center on Highway 17 is open Wednesday to Saturday, 9 to 5.

• Warblers out, sparrows and kinglets in

  Through October · Hedgerows, wax myrtle thickets and park edges statewide

  Yellow-rumped warblers arrive for the winter and work the coastal wax myrtles, whose waxy berries few other birds can digest. Kinglets and white-throated sparrows follow, and the last hummingbirds slip away.

When do monarchs pass through South Carolina?

• Groundsel bushes on the islands

  Flowering August through October · Dune edges and marsh margins; Folly, Sullivan’s, Kiawah, Huntington Beach

  The late monarchs fuel up on groundsel tree, a native coastal shrub that the Wildflower Center lists in flower in August, September and October. Male and female flowers grow on separate plants, and in fall the females turn silvery with plumed seeds, as if dusted with frost. A north-wind day at Huntington Beach State Park can put a steady line of monarchs low over the dry sand; one Monarch Watch correspondent estimated ten thousand in a single day there.

• Monarch City in the Upstate

  September into October · Greer and pollinator gardens across the Upstate

  Greer is the first community in South Carolina named a Monarch City USA, and its pollinator gardens are a stopover in the September-to-November passage. In the Upstate the flight is close to done by mid-October, so the last monarch on a zinnia there is worth a dated note on the pollinator watch plate.

What changes on the South Carolina coast in October?

• Oysters and clams reopen

  Opens half an hour before sunrise, Thursday, October 1; through May 15, 2027 · Public and State Shellfish Grounds with open water quality

  The daily limit is two U.S. bushels of oysters and half a bushel of clams, on no more than two calendar days in any seven, with at most three personal limits per boat or vehicle, and clams must be at least an inch thick. Twenty-seven grounds are reserved for recreational pickers. Rain, spills or a storm can close grounds overnight, so check the state’s shellfish closure map or call 1-800-285-1618 before you go. Cull in place, leaving dead shell and small oysters on the bed, and recycle your shells.

• Fall white shrimp

  Shrimp baiting season, noon September 11 to noon November 9 · Creeks, sounds and tidal rivers

  The fall shrimp are white shrimp, grown fat in the estuaries over the summer. SCDNR says they head out to the ocean when the water falls to about 60 to 65 °F, usually at four to five inches long. The 60-day baiting season is fixed by law and opens at noon on the last Friday on or before September 15; the resident license is $25, and baited shrimp may not be sold.

• The last loggerhead nests of a big year

  Nesting season officially ends October 31 · Cape Romain, Kiawah, Edisto, Hilton Head and beaches statewide

  The 2026 season was one of the strongest ever recorded. Preliminary counts on seaturtle.org stand at 8,038 loggerhead nests, plus 15 green turtle nests and a Kemp’s ridley; the state record is 8,775, set in 2019, and 2025 managed only 3,902. By August 10 Cape Romain alone had 3,437. Laying ended in August; volunteers watch the final nests hatch through October. Keep beachfront lights off, fill holes and knock down sandcastles, and call SCDNR at 1-800-922-5431 for a sick, injured or dead turtle.

• King tides, October 26–28

  Morning high tides, Monday through Wednesday, starting the day of the full moon · The Charleston peninsula and low-lying coastal roads

  October is the tide-flooding month in Charleston: NWS Charleston’s records count more minor flood events at the harbor gauge in October than in any other month. NOAA’s predictions for Charleston Harbor this year peak at 6.76 feet above mean lower low water at 8:18 a.m. on October 26, 6.87 at 9:06 a.m. on October 27 and 6.85 at 9:57 a.m. on October 28. Minor flooding begins at 7.0 feet, so the forecast sits just under the line, and an onshore wind or a rainy morning can push it over. NWS Wilmington has already flagged October 26–28 for possible sunny-day flooding on the northern coast.

What can you see in South Carolina’s night sky this October?

• The moon hides Jupiter

  Tuesday, October 6, about 4:16 to 5:20 a.m. EDT · Low in the east; the moon 12 to 14 degrees up at the start

  The crescent, 20 percent lit, clears the horizon around 3 a.m. (3:03 in Charleston, 3:10 in Greenville), the planet glittering beside it. IOTA, the occultation timers’ association, lists the vanishing at 4:17 a.m. in Charleston, Myrtle Beach and Charlotte and 4:16 in Augusta and Savannah, with the moon 12 to 14 degrees high. Jupiter pops back out from the unlit side at 5:19 in Charleston, 5:20 in Myrtle Beach and Charlotte, 5:18 in Augusta and 5:17 in Savannah, the moon then standing 24 to 27 degrees high. Columbia and Greenville are absent from the list, but their times should differ by only a minute or so. Both events come in full darkness, well over an hour before dawn twilight begins. Binoculars are enough to watch it go.

• The Hunter’s Moon

  Evenings of Sunday, October 25 and Monday, October 26 · Rising in the east-northeast

  Fullness comes at 12:12 a.m. Monday, so Sunday and Monday evenings both offer a full-looking moon. Sunday it rises at 6:04 p.m. in Charleston and 6:07 in Columbia, half an hour before the sun goes down; on the 26th it comes up at 6:43 and 6:44, a few minutes after sunset. Despite what you may read, this one is no supermoon. Its pull, with the sun’s, drives the king tides that follow.

• Orionid meteors

  Before dawn, October 21 and 22 · Anywhere dark, facing southeast and up

  Halley’s Comet left the grit that makes the Orionids, which fly from early October into early November and peak broadly on October 21–22. A fat waxing moon lights the evening, but it sets at about 3:45 a.m. on the 22nd (3:44 in Charleston, 3:47 in Columbia, 3:52 in Greenville), leaving a dark sky until the east begins to pale after 6. A dark rural site might show a dozen or so swift meteors an hour in a decent year.

• Draconids on a moonless evening

  Thursday evening, October 8 · The northern sky after dark

  A sparse shower of slow meteors that is best soon after dark, which makes it a school-night event. The moon stays below the horizon until the next dawn, and new moon two days later brings the darkest skies of the month.

• Planets: Saturn all night, Jupiter and Mars at dawn

  Saturn at opposition October 4; Mars in the Beehive October 11 · Saturn east at dusk; Jupiter and Mars east before sunrise

  Saturn sits opposite the sun on October 4, climbing out of the east as daylight fades and lingering till morning, and the moon passes it on October 23–24. Venus is a western-twilight object only through about the first weekend, and it lines up between Earth and sun, unseen, on October 23. In the morning Jupiter blazes in the east, and Mars, higher and fainter, threads the Beehive cluster in Cancer on the dawn of October 11, a lovely binocular sight.

What is blooming and ripening in South Carolina in October?

• Muhly grass in pink

  Flowering from October, fading to tan through winter · Dunes, roadsides, yards and parking-lot islands statewide

  Clemson’s Home & Garden Information Center describes the native muhly as clouds of tiny pinkish-purple flowers that appear in October over blue-green leaves two to three feet tall. It is drought tolerant once established, which shows this year. The same genus includes the sweetgrass that Lowcountry basket makers have sewn for generations.

• Groundsel tree turning silver

  Flowering into October; seed plumes on female plants in fall · Marsh edges, ditches and old fields, most common near the coast

  Groundsel tree, also called saltbush, is where the coastal monarchs feed. By late October the female shrubs look like silvery paintbrushes, covered in fluffy seeds, while the males stay plain. The Wildflower Center notes that it once kept to the outer coastal plain but has spread well inland.

• Goldenrods and asters

  Until the first freeze · Roadsides, powerline cuts, marsh edges

  Seaside goldenrod on the dunes, tall goldenrod in the fields and a spread of white and purple asters carry the bees and butterflies into November. Goldenrod gets blamed for fall allergies, but its pollen is heavy and bee-carried; ragweed, blooming at the same time with no showy flowers at all, is the culprit.

• Persimmons

  Fruit September through November · Old fields, fencerows and pastures, often in thickets

  The USDA’s plant guide warns that the pulp is highly astringent until it ripens, turning orange and sweet in the fall. A persimmon is ready when it is soft and wrinkled and drops at a touch; before then one bite teaches the lesson for life. Foxes, raccoons, opossums and deer all find the trees, so a persimmon thicket is a fine spot to hunt for tracks in soft ground.

What are South Carolina’s deer, bears and spiders doing?

• The rut begins

  Generally the last two weeks of October through the first two weeks of November · Statewide; along every rural highway at dusk

  That is SCDNR’s general answer to when South Carolina deer breed, with the caveat that breeding can show up almost any time in fall and winter. Bucks rub saplings and paw scrapes under low branches, and they move in daylight more than usual, often straight across the road. Slow down at dawn and dusk, and if one deer crosses, wait for the second.

• Bears putting on weight

  Through the fall, before winter dens · The mountains and upper Piedmont, and a separate population in the coastal plain

  SCDNR recognizes two resident populations of black bears, one in the mountains and upper Piedmont and one in the coastal plain. BearWise says a fall bear can spend as many as 20 waking hours a day hunting food, mostly acorns and anything else they can find, and a drought year with a thin acorn crop can push them toward garbage, bird feeders and pet food. BearWise’s October advice is to take the feeders down, secure the trash and recycling, and watch for bears crossing roads at dusk and dawn.

• Joro spiders at their biggest

  Peak in September and October · Porches, powerlines, fences and tree limbs

  The large yellow, blue-green and red females of this spider from East Asia spin golden webs that stretch across paths and porches. The University of Georgia’s extension bulletin says they pose no documented threat to people, are not aggressive and can be moved off a path with a stick. They are established in South Carolina and spreading.
