1991-2020 mediansThe Upstate near the Blue Ridge sees snow most winters. Columbia manages it about every other year, and Charleston's snows are storied precisely because they are rare.
First snow dates across South Carolina
A state average would hide the real story: elevation, latitude, and nearby water move first snow dates by weeks inside South Carolina. Each row below is one NOAA station's own record over the 1991 to 2020 climate normals period.
| Station | Median first snow | First 1 inch | Winters with snow | Earliest on record |
|---|---|---|---|---|
| Greenville | January 22 | January 29 | 90% | November 11, 1968 (1.9 in) |
| Columbia | Fewer than half of winters | Most winters never | 50% | December 3, 1971 (0.8 in) |
| Charleston | Fewer than half of winters | Most winters never | 13% | December 11, 1958 (0.1 in) |

The three first snows of every winter
Every winter actually has three openings, and they are weeks apart. The first flakes come earliest: a trace in the air that melts on contact and never counts in the record books. The first measurable snow, 0.1 inch or more, is what this page tracks and what lands around January 22 at Greenville. The first inch, the one that changes the morning commute, typically waits until around January 29.
The gap exists because early season snow fights a warm ground. The first systems cold enough to snow are usually moisture starved, and the first wet storms are usually a degree or two too warm. When both line up, that is the date neighbors remember.

How the South Carolina dates are calculated
NOAA publishes official 1991 to 2020 climate normals for seasonal snowfall totals, but not for first snow dates. The dates here are derived from NOAA's raw daily station records (GHCN-Daily): for each station, the first day of each July to June snow season with at least 0.1 inch of snowfall, across the 30 seasons of 1991-92 through 2020-21, reported as the 10th, 50th, and 90th percentile dates. Winters with gappy reporting are excluded rather than guessed, values that failed NOAA's own quality checks are skipped, and record earliest dates use each station's full period of record from 1872 onward.
Treat the median as a planning anchor, not a promise: any single winter can run two to three weeks either side, and your neighborhood's elevation can move it as much as the calendar does. Once you are inside the window, the 10 day forecast takes over from climatology.

First snow = first day with 0.1 inch or more of snowfall at the named NOAA station (trace flurries excluded). Medians and windows are our derivation from NOAA NCEI GHCN-Daily records over 1991-2020; seasonal snowfall normals are NOAA's official figures. National picture: first snow dates for every state
