Monsoon Storms and Shortgrass Prairie Seasons
From July through September, the monsoon season brings thunderstorms that build quickly and release heavy rain within a short window.
Flash floods, lightning and strong gusts are the main risks, so move away from open ground when storms start to build. Afternoon storms are especially common in July and August.
The park sits at about 5,400 feet, which keeps it a little cooler than Phoenix. Its main environment is semi-arid grassland, classed as shortgrass prairie, though it is sometimes called a high desert. Summer highs from June through August commonly fall between 90 and 100 degrees, while winter nights can drop well below freezing. About 10 inches of moisture arrives as infrequent winter snow and summer storms.
Warm days and little rain make spring and fall the most comfortable seasons for a trip. Winter is colder, though daytime highs can still reach the 50s, which suits hiking and short walks. Snow sometimes dusts the landscape, as it does at Blue Mesa, and from October through April cold temperatures and possible snow are worth expecting.
The grassland supports elk, mule deer, pronghorn, coyotes, badgers and prairie dogs. Burrowing owls, roadrunners and golden eagles also live here. Several short hiking trails cross the park, including the Blue Mesa Trail, along with Crystal Forest, Giant Logs and Puerco Pueblo.
High winds are common and can carry blowing sand that makes hiking unpleasant. Bring at least a gallon of water for each day, since heat and dry air can quickly lead to dehydration.
