Climate Insight: Beaufort Mcas, SC

The NOAA 1991–2020 climate normals describe Beaufort Mcas, South Carolina as a location with an annual average temperature of 67°F, ranging from a mean daily high of 77°F to a mean daily low of 58°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USW00093831, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Beaufort Mcas receives roughly 45.0 inches of precipitation each year, with seasonal snowfall possible. Growing-season length varies with elevation and microclimate, with the last spring freeze near February 28 and the first fall freeze near December 3. For energy use, 1,732 heating degree days and 2,570 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Beaufort Mcas scores 92/100 (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.
