A "white Christmas" is defined as having an inch or more of snow on the ground on Christmas morning. How common is that in the Cincinnati area? Since snow depth measurements began in Cincinnati in 1916, the area has experienced a white Christmas only 18 times (about 17 percent of the time).
During the most recent 30-year climatological normal period (1991-2020), the area experienced a white Christmas just 7 times (23 percent of the time). Cincinnati's most recent white Christmas occurred in 2022 when there was 2 inches of snow on the ground in the morning.
