Climate Guides

Climate Insight: Blackville, SC

An annual average temperature of 64°F, ranging from a mean daily high of 75°F to a mean daily low of 53°F is what the NOAA 1991–2020 climate normals report for Blackville, South Carolina. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USW00063826 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.

Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Blackville sees about 46.2 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 238 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near March 20 and the first fall freeze near November 13. On the energy side, 2,383 heating degree days and 2,006 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Blackville scores 88/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows, shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
