. . . is you gotta be tough to live down here in Mid-Michigan. Having lived in the UP, I know that dressing appropriately allows inhabitants of the great, white north to enjoy winter to the fullest, the roads are better after worse weather, and I never saw an SAD light, although I would be interested in trying one. Having lived in Lower Michigan, I know that abundant, cloudy weather makes it difficult to motivate for outdoor recreation, especially since those clouds are most likely to bring wind and rain rather than glorious snow.

Rumor has it that “a city” in Michigan is one of the cloudiest cities in the United States, and some people will rank it as either number one or two, but this is not true. It is true, however, that Michigan is pretty darn cloudy, and it doesn’t take a genius or fancy meteorological equipment to figure that out.

I decided to find a worthy source for data pertaining to the amount of cloud cover throughout the United States. I checked with NOAA, the National Oceanic and Atmospheric Administration.

NOAA has a beautiful, plain-text web page with the “Ranking of Cities Based on % Annual Possible Sunshine in Descending Order from Most to Least Average Possible Sunshine.” For those of you who are mathematically challenged, this means that the sunniest city, which is Yuma, Arizona, is at the top of the list with 90% annual average possible sunshine. The cloudiest city, which is Juneau, Alaska, is at the bottom of the list ranking at 174 with 30% annual average possible sunshine.

Disclaimer: NOAA did not Di-proof the data by assigning each city with a rank, so I had to count down the list to figure out the Michigan rankings and the total number of cities where observations were made. Simply put, the rankings could be off by one or two, but that really doesn’t change my point. In hindsight, I should have copied and pasted the information into Word and then created an ordered list. Ah, well, live and learn.

Data was collected at the various sites for differing amounts of time up until 2004. The least data was collected in Pensacola, Florida for only five years, whereas the most data was collected in Blue Hill, Massachusetts for 112 years.

How does all of this affect Michigan? Well, data was collected at six Michigan locations: Alpena, Detroit, Grand Rapids, Lansing, Marquette, and Sault Ste. Marie (soo SAINT marIE for those of you who are not familiar with the funky pronunciations of Michigan cities). Data was collected for varying amounts of time:

• Alpena – 37 years

• Detroit – 31 years
• Grand Rapids – 36 years
• Lansing – 42 years
• Marquette – 21 years
• Sault Ste. Marie – 55 years

Detroit (dee TROIT ) was the first city to rank on this fantastic list at 140 with 53% annual average possible sunshine, while Grand Rapids was the cloudiest observed Michigan city ranking at 161 with only 46% annual average possible sunshine:

• 140 Detroit 53%

• 147 Lansing 51%
• 151 Marquette 50%
• 155 Alpena 48%
• 159 Sault Sainte Marie 47%
• 161 Grand Rapids 46%

Since Seattle is often used as a comparison for cloudiness, for the sake of comparison, it ranks at 160 with 47% annual average possible sunshine, just above Grand Rapids. Of the observed cities, the only ones with lower annual average possible sunshine are in Hawaii – yes, Hawaii – New Hampshire, New York, Pennsylvania, Washington, West Virginia, and some U.S. territories.

While Michigan’s cities are not the cloudiest, or even the second cloudiest, they are most certainly at the bottom of the totem pole for sunshine. On average, Michigan cities have 49% annual average possible sunshine, which works out to about 179 sunny days per year.
