About Grand Traverse County Weather

Temperate Living in Northern Michigan

Grand Traverse County maintains an average annual temperature of 46.1°F, which is cool compared to the national median. The regional climate is heavily influenced by its proximity to Lake Michigan, which moderates temperature swings.

Slightly Warmer Than State Norms

Despite its northern position, the county’s 46.1°F average is slightly warmer than the Michigan state average of 45.7°F. This lake-moderated climate helps it stand out from colder, more landlocked northern counties.

Managing Significant Lake-Effect Snow

The county receives 101.0 inches of snow annually, which is significantly higher than many inland Michigan counties. Total annual precipitation averages 32.2 inches, trailing just behind the state average of 34.5 inches.

Four Distinct and Active Seasons

January temperatures average 22.6°F, but the lake-effect keeps the air from reaching extreme lows found further inland. July remains comfortable at 69.3°F with only 7 days of extreme heat reaching 90°F or higher.

Balance Snow Tools with Summer Gear

Reliable snow tires and winterized vehicles are essential for navigating the 101.0 inches of annual snowfall. HVAC systems should be rated for both cold winters and the occasional week of 90°F summer humidity.
