Snowfall on Mackinac Island
In addition to cooler temperatures from Halloween through Easter, Mackinac Island also gets a lot of snow. While it is possible for a few flakes to fall in October or May, almost all of the 94 inches of average annual snowfall comes from November through April. No wonder Mackinac Island residents tend to get around on snowmobiles in the winter! January is the snowiest month of the year on Mackinac Island. So, if there isn’t already a nice base of snow on the ground by the time of Mackinac Island’s Great Turtle Drop on New Year’s Eve, then there will be soon. That’s why Mackinac Island State Park is a great place for cross-country skiing and fat-tire biking. Mackinac Island’s Great Turtle Twilight Trek, which is a lighted ski path through the woods, is definitely a winter activity that’s worth the trip for visitors. Winter also tends to be a little windier than summer on Mackinac Island, which is all the more reason to spend time exploring the protected woods of Mackinac Island State Park. And because Mackinac Island is rather far north, the winter days can be pretty short. December and January only get about 9 hours of daylight each day.
