What Jefferson's climate means for you
Jefferson runs 51°F a year - peaking in July, coldest in January.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
Based on station USC00314496 feeding NOAA's 1991–2020 climate normals, Jefferson, North Carolina averages 51°F a year, ranging from a mean daily high of 63°F to a mean daily low of 39°F. July is typically the warmest month of the year, while January is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.
Jefferson averages 51.0 inches of precipitation a year, with 14.4 inches typically falling as snow, and that matters as much to daily life here as temperature does. The frost-free season averages 154 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 7 and the first fall freeze near October 8. As for energy demand, 5,448 heating degree days and 408 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Jefferson scores 54/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above are the practical planning tool: mild highs and lows land in the shoulder seasons, July-driven heat peaks in summer, and January-driven cold sets in over deep winter. These are thirty-year averages, not a forecast - any single year can run warmer, wetter, drier, or cooler than the normal.
