Climate Insight: Alpena CO Rgnl, MI

The NOAA 1991–2020 climate normals describe Alpena CO Rgnl, Michigan as a location with an annual average temperature of 44°F, ranging from a mean daily high of 55°F to a mean daily low of 34°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USW00094849, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Alpena CO Rgnl receives roughly 29.7 inches of precipitation each year, with 77.6 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near May 17 and the first fall freeze near October 1. For energy use, 7,844 heating degree days and 353 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Alpena CO Rgnl scores 47/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
