The park drew an average of 2.9M recreation visits a year over 2016–2025. July is the busiest month at 26.9% of the year's visits, and February the quietest — 50.5× fewer people.

Crowds

July averages 787,452 recreation visits against 15,607 in February. Visit counts are the National Park Service's own monthly totals for the whole park, so unlike the weather figures below they describe every entrance and every trailhead at once.

Conditions through the year

July is the warmest month at 5,522 feet, averaging a daily high of 70°F, and February the coldest at 21°F with lows near 9°F. February is the wettest at 5.2 inches, July the driest at 1.6.

Daylight runs from 8h 18m in December to 16h 6m in June, a difference of 7h 48m of usable time in a day.

Snow shows up in every month except July and August. That is snowfall at the grid cell, not road or trail status — parks close roads on their own schedule and conditions, and the park's own alerts are the only authority on what is open.

Read the temperatures this way

Those temperatures come from a reanalysis grid cell centred at 5,522 feet. A park that spans a range of elevations is warmer in some places and colder in others than one cell can show, and most parks span a wide one. Read the month-to-month shape — which months run warm, wet or snowy relative to each other — rather than any single figure as the temperature you will meet at a given trailhead.

There is no best month here

This page does not pick one. Crowds and weather alone cannot: in the desert parks the emptiest months are empty because the heat is dangerous, and in the mountain parks the quietest ones are quiet because the roads are shut. What a month has usually been like and what it will be like on your date are also different claims — for the second, the planner reads the live seven-day forecast and the park's own notices.
