FLINT, MI

Overview:
This station is located at Bishop International Airport, located in central Genesee County. Flint lies on the Flint River, about 41 miles south of Saginaw Bay and about 65 miles west of the southern tip of Lake Huron. Overall, the terrain is flat, and while there are mixed forests throughout the area, large expanses of agricultural land dominate the region.

Flint experiences a continental type of climate characterized by larger temperature ranges than surrounding areas near the Great Lakes which have moderated temperatures. Summers are warm and humid. Winters are often cold with abundant snowfall. Diminished wind speeds or winds which do not traverse large unfrozen lakes often produce clearing skies and the colder temperatures expected at continental locations. As a result of prevailing westerly winds, Flint does experience some lake effect. However, this is minimal and essentially limited to increased 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.
