Flagstaff has a rather dry continental climate with four distinct seasons. The combination of high elevation and low humidity provide mild weather conditions throughout most of the year, and the predominantly clear air radiates daytime heating effectively. Temperatures often fall precipitously after sunset throughout the year, and winter nights can be very cold. Despite being fewer than 150 miles (240 km) from Phoenix, the mean annual temperature is 28.8 °F (16.0 °C) cooler, due primarily to its higher elevation.
Winter weather patterns in Flagstaff are cyclonic and frontal in nature, originating in the eastern Pacific Ocean. These deliver periodic, widespread snowfall followed by extended periods of fair weather. The area's generally stable weather pattern is broken by brief, but often intense, afternoon downpours and dramatic thunderstorms common during the so-called monsoon of July and August.
