Climate Insight: Tower, MN

In Tower, Minnesota, the NOAA 1991–2020 climate normals put the annual average temperature at 37°F, ranging from a mean daily high of 49°F to a mean daily low of 25°F. July is typically the warmest month of the year, while January is the coldest. As thirty-year averages computed from station USC00218311, these numbers smooth out year-to-year noise into a working baseline for a typical month.

Tower averages 28.2 inches of precipitation a year, with 68.7 inches typically falling as snow, and that matters as much to daily life here as temperature does. Growing-season length varies with elevation and microclimate. As for energy demand, 10,348 heating degree days and 159 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Tower scores 47/100 (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.
