Climate Insight: Beaufort Mcas, SC
An annual average temperature of 67°F, ranging from a mean daily high of 77°F to a mean daily low of 58°F is what the NOAA 1991–2020 climate normals report for Beaufort Mcas, South Carolina. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USW00093831 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
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 negligible snowfall. The frost-free season averages 278 days, which directly shapes the planting calendar and growing potential for the area, 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 97/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, July-driven heat at the peak of summer, and January-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
