The best time to visit Mackinac Island is during the summer months from June to September. The weather is warm, with daytime temperatures ranging between 21°C and 27°C (70°F to 80°F), making it perfect for outdoor activities like biking, hiking, and horse-drawn carriage tours. Summer is also when the island comes alive with events, festivals, and open shops, offering a vibrant and bustling atmosphere. However, because this is the peak season, you'll also encounter larger crowds and higher accommodation prices.
Spring (May) and fall (late September to October) offer cooler temperatures and fewer tourists, with fall in particular showcasing stunning autumn foliage. These shoulder seasons are ideal for visitors looking to experience the island at a slower pace and enjoy lower prices. However, keep in mind that some businesses may have limited hours, especially in early spring and late fall.
Winter (November to April) is the off-season, and while the island transforms into a quiet, snow-covered landscape, most attractions and accommodations are closed. However, if you’re an adventurous traveler, cross-country skiing and snowshoeing provide a unique way to explore Mackinac’s winter wonderland.
