SAGINAW, MI (MBS INTERNATIONAL AIRPORT)

Overview:
Saginaw is a city situated near the geographic center of Lower Michigan. Distanced from Lakes Michigan and Huron, temperature variations are larger than in some areas of Michigan. The city of Saginaw lies on the Saginaw River and is 15 miles inland from the Saginaw Bay, which is an arm of Lake Huron.

Normal precipitation varies little from month to month during the growing season, with 3.33 to 3.79 inches falling during the months of May, June, August, and September with amounts between 2.60 and 2.86 inches in April, July, October, and November. While annual normal precipitation is similar to locations closer to Lake Michigan, winter precipitation is lower due to lesser amounts of lake-effect snow.

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.
