The peak summer months of July and August offer the warmest weather, great for those who enjoy outdoor events and festivals.For those who prefer slightly cooler temperatures and fewer crowds, May, June, September, and October are excellent choices. These shoulder seasons often provide comfortable weather for walking, cycling, and visiting attractions like the Holyoke Heritage State Park without the intense heat of mid-summer.
