Climate Insight: Florence, WI

An annual average temperature of 40°F, ranging from a mean daily high of 51°F to a mean daily low of 30°F is what the NOAA 1991–2020 climate normals report for Florence, Wisconsin. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00472826 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.

Beyond temperature, Florence averages 30.4 inches of precipitation annually, with 65.6 inches typically falling as snow - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 124 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 24 and the first fall freeze near September 25. Turning to energy use, 9,149 heating degree days and 231 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Florence scores 44/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings July-driven heat, and winter brings January-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
