Introduction to Sunnyvale, California

Sunnyvale was incorporated in 1912 and is the 34th largest city in California. The city is home to approximately 130,000 inhabitants. The metropolitan area including San Jose, Sunnyvale, and Santa Clara has a population of about 1.7 million people. Sunnyvale is located 40 miles southeast of San Francisco, in the heart of the Silicon Valley. It is 4 miles from San Francisco Bay and 25 miles from the Pacific Ocean.

When the Spanish first arrived in the late 1700's, Ohlone Indians populated the Santa Clara Valley, in which present day Sunnyvale is located. The valley is also now referred to as "Silicon Valley". In the 1870's, a wheat economy gave way to one based on fruit, aided by the innovation of refrigerated rail cars. In 1905, marine steam engines were produced here, the region's first non-agriculture product. The transition to high tech began during World War II. However, the term Silicon Valley was not used to describe the area until 1971.

In 2002 Sunnyvale was one of the "Finalist Communities" for the "All-America City Award" given by the National Civic League.

In July the average daily high is 79 degrees Fahrenheit while the average daily low temperature is 57 degrees. In January the average daily high temperature is 58 degrees Fahrenheit. The January average daily low is 40 degrees.
