The NOAA 1991–2020 climate normals describe N Myrtle Bch, South Carolina as a location with an annual average temperature of 64°F, ranging from a mean daily high of 73°F to a mean daily low of 55°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USW00093718, 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. N Myrtle Bch receives roughly 48.5 inches of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate, with the last spring freeze near March 13 and the first fall freeze near November 20. For energy use, 2,343 heating degree days and 2,003 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, N Myrtle Bch scores 87/100 (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.
