Climate Insight: Winona, MN
Based on station USC00219067 feeding NOAA's 1991–2020 climate normals, Winona, Minnesota averages 49°F a year, ranging from a mean daily high of 58°F to a mean daily low of 40°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.
Anyone planning to live, garden, or travel in Winona should weigh precipitation alongside temperature: the annual average runs an uncharted amount, predominantly as rainfall. The frost-free season averages 181 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 21 and the first fall freeze near October 19. And on the energy front, 6,780 heating degree days and 910 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Winona scores 53/100 (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.
