◎ mild weather (average high 55–85°F) and under 60% of the park's busiest month · ○ mild but busy · △ mild but under 30% of peak, often seasonal closures · × cold or hot. “Best month” = this is the park's best balance of crowds and weather. Crowds compare each park with its own busiest month, so a “quiet” big park can still be busier than a small one — check visitors per day.

Weather is a 30-year average at one station per park (often the park headquarters). Mountain roads and high trails can still be snowbound in shoulder months, so check each park's current conditions on nps.gov before you go.
