ADRIAN, MI

Overview:
Adrian, located in central Lenawee County, is about 13 miles north of the Ohio border and about 30 miles west of Lake Erie. Soils vary from clay loams toward the west to poorly drained clay and clay loams to the south, while sand and sandy loams are predominant elsewhere.

Precipitation varies little throughout the year, with the wettest months of the year occurring during the warmer months. Temperatures rarely exceed 90°F in Adrian but there are, on average, more than 130 days where the temperature is less than 32°F. Lake effect precipitation is limited in Adrian. Easterly winds bring cloudiness during the late fall and early winter.

Annual High and Low Temperature Departure

Cold Temperatures

¹Heating Degree Days (HDDs) are indexed units, not actual days, that roughly describe the demand to heat a building. HDDs accumulate on days colder than 65°F when heating is required. Every degree below 65°F is added to the annual total for an annual HDD value, which is plotted in the figure.

Hot Temperatures

²Cooling Degree Days (CDDs) are indexed units, not actual days, that roughly describe the demand to cool a building. CDDs accumulate on days warmer than 65°F when cooling is required. Every degree above 65°F is added to the annual total for an annual CDD value, which is plotted in the figure.
