The climate of Mackinaw City is influenced by the lakes, with cool breezes moderating the summer heat, and winter bringing a snowy, icy winter wonderland. Spring and summer are the best time to visit for outdoor activities, although there may be occasional thunderstorms. Autumn is also a lovely season, with mild days and cool nights, ideal for exploring the countryside. In winter the area is blanketed in deep snow.

Visitors to Mackinaw City can make use of the Mackinaw Trolley Company, which offers 2, 5 hour tours of the city, pointing out attractions and narrating its history.
