With warm and pleasant temperatures and more than 15 hours of daylight at its peak, summer is when the Adirondacks really shine. Although the region can experience heatwaves, occasional humidity, and sudden rainstorms this time of year, June through August is generally ideal for outdoor recreation, drawing more visitors to the Adirondacks than all the other seasons combined.

Summer Conditions

- June – Through mid-month, trails are still generally muddy and wet from melting snow, particularly on high-elevation trails, so hikers are advised to wear waterproof boots.
