Climatic conditions exhibit a distinctly bimodal pattern, with spring and fall having low moisture, and summer and winter having high precipitation. Precipitation within the Monument averages 19.52 inches a year, most of which falls as localized, heavy rain during the summer monsoons, occurring from July through mid-September. Summer rainfall occurs as high intensity thunderstorms, while winter rainfall is usually associated with Pacific frontal storms. Snowstorms can occur from late fall through early spring, and may bring up to a foot of snow, but the snow rarely lingers except on the shaded northern slopes at the highest elevations.
