Climate Insight: Tecumseh, MI
The NOAA 1991–2020 climate normals describe Tecumseh, Michigan as a location with an annual average temperature of 49°F, ranging from a mean daily high of 60°F to a mean daily low of 37°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00208080, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Tecumseh sees about 36.0 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 163 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 3 and the first fall freeze near October 13. On the energy side, 6,580 heating degree days and 631 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Tecumseh scores 64/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings July-driven heat, and deep winter brings January-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
