Climate Insight: Savannah, TN
An annual average temperature of 62°F, ranging from a mean daily high of 73°F to a mean daily low of 50°F is what the NOAA 1991–2020 climate normals report for Savannah, Tennessee. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00408108 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Anyone planning to live, garden, or travel in Savannah should weigh precipitation alongside temperature: the annual average runs 59.2 inches, predominantly as rainfall. The frost-free season averages 215 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near March 31 and the first fall freeze near November 1. And on the energy front, 3,157 heating degree days and 1,930 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Savannah scores 78/100 (Good), 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.
