Sierra Vista, which is Spanish for “Mountain Range View”, is located 75 miles (121 km) southeast of Tucson and serves as the main commercial, cultural, and recreational hub of Cochise County.
Sierra Vista is flanked on the southwest side by the Huachuca Mountains, with Miller Peak rising to 9,466 feet (2,885 m) and Carr Peak to 9,236 feet (2,815 m), both south of the city limits. The city is accessible via Arizona State Routes 90 and 92. The San Pedro River flows just east of the city limits. Like most of Cochise County it was part of the Gadsden Purchase. At the end of the Apache Wars, with the protection of Fort Huachuca and the completion of the Southern Pacific and El Paso & Southwestern railroads, the San Pedro Valley began to populated by American Settlers.
Sierra Vista is bordered on the northwest by the much smaller town of Huachuca City. The first business that opened just outside the east gate of Fort Huachuca was in 1892. Nicknamed the “Hummingbird Capital of the United States”, the city sees bird watchers from all over the world flock to the nearby Ramsey Canyon Preserve and other local canyons to observe and photograph hundreds of different bird species. Other outdoor sightseeing and recreational opportunities that are nearby include the San Pedro Riparian National Conservation Area, the Coronado National Memorial in the Huachuca Mountains, and Parker Canyon Lake.
Fall and spring, like most other parts of Arizona, are very dry. Winters are cool to cold with frosts which can occasionally be hard freezes; frost can be expected to stop in mid- to late April. Spring, like fall, spends about half of itself within the frost season. Summer starts off dry, but progressively gets wetter as the monsoon season approaches. The city has a fairly stable climate with very little humidity. However, the North American Monsoon can bring torrential rains during the months of July and August and will produce almost half the yearly rainfall in just those two months alone. Due to the dry climate the rest of the year and the city’s high elevation, daily winter low temperatures range from 20 to 30 °F (−6.7 to −1.1 °C) on average and up to 50 °F (10.0 °C) on rare occasions when moist fronts bring warm air from the Gulf of California.
