Michigan Temperature Records
- Hottest temperature ever recorded: 112 F, Mio, northern Michigan, 7/13/1936
- Coldest temperature ever recorded: -51 F, Vanderbilt, northern Michigan, 2/9/1994
- Hottest location ranked by highest average annual temperature: Ypsilanti, southeastern Michigan, 50.2 F
- Coldest location ranked by lowest average annual temperature: Herman, western Upper Peninsula, 39.1 F
- The winter of 2002-2003 was one of the most enduring winters on record at Detroit, Michigan. From January
through February, the temperature stayed below 40 degrees 90% of the time and lower than 32 F for 76% of the
time. In addition to continuously cold temperatures, it was the driest winter on record with only 2.24" of
precipitation from December through February.
The lake effect imparts many interesting departures to Michigan’s climate which one would not ordinarily expect to find at a mid-latitude location. Due to the lake waters’ slow response to temperature changes and the dominating westerly winds, the arrival of both summer and winter are retarded. In the spring, the cooler temperatures slow the development of vegetation until the danger of frost is past. In the fall, the warmer lake waters temper the first outbreaks of cold air, allowing additional time for crops to mature or reach a stage which is free from damage by frost. This modification in temperature extremes by the lakes enables Michigan to produce successfully a variety of crops more ideally suited to the climate of states much further south.
With the first cold outbreaks in the fall, Michigan experiences a considerable increase in cloudiness. When cold air passes over the warmer lake water, a shallow layer of unstable, moisture-laden air develops in the lower levels of the atmosphere. This air, when forced to rise, produces the increased cloudiness and frequent snow flurry activity observed in the fall and early winter months. A comparison of percent of possible sunshine in December showed Lansing receiving 27 percent, while Madison, Wisconsin received 42 percent. The difference decreases slowly as the lake waters cool, but does not completely disappear until the latter part of February.
