Climate Insight: Frankfort, MI

An annual average temperature of 47°F, ranging from a mean daily high of 54°F to a mean daily low of 39°F is what the NOAA 1991–2020 climate normals report for Frankfort, Michigan. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00202984 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.

Beyond temperature, Frankfort averages 34.3 inches of precipitation annually, with 93.0 inches typically falling as snow - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 177 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 2 and the first fall freeze near October 26. Turning to energy use, 7,107 heating degree days and 396 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Frankfort scores 54/100 (Moderate), 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.
