San Bruno, California
San Bruno (from Spanish 'St. Bruno') is a city in San Mateo County, California, United States, incorporated in 1914. The population was 43,908 at the 2020 United States census. The city is between South San Francisco and Millbrae, adjacent to San Francisco International Airport and Golden Gate National Cemetery; it is approximately 12 miles (19 km) south of Downtown San Francisco.
The city is located between South San Francisco and Millbrae, adjacent to San Francisco International Airport to the east and Golden Gate National Cemetery to the northwest. It is approximately 12 miles (19 km) south of Downtown San Francisco.
According to the United States Census Bureau, the city has a total area of 5.5 square miles (14 km2), all of it land. The city spreads from the mostly flat lowlands near San Francisco Bay into the foothills of the Santa Cruz Mountains, which rise to more than 600 feet (180 m) above sea level in Crestmoor and more than 700 feet (210 m) above sea level in Portola Highlands. San Bruno City Hall sits at an official elevation of 41 feet (12 m) above sea level.
Portions of Mills Park, Crestmoor, and Rollingwood are very hilly, featuring canyons and ravines. Creeks, many of them now in culverts, flow from springs in the hills toward San Francisco Bay. Just west of Skyline Boulevard and outside of city limits is San Andreas Lake, which got its name from the San Andreas Fault. The lake is one of several reservoirs used by the San Francisco Water Department, providing water to San Francisco and several communities in San Mateo County, including San Bruno west of I-280.
San Bruno has a mild Mediterranean climate characterized by mild to warm, dry summers and cool, wet winters. San Bruno has much milder temperatures than most of the state. Owing to its relatively mild temperatures, the city's climate closely resembles that of an oceanic climate. Since 1927, the National Weather Service (formerly the U.S. Weather Bureau) has maintained a weather station at the nearby San Francisco International Airport (formerly Mills Field). According to the official records, January is the coldest month with an average high of 55.9 °F (13.3 °C) and an average low of 42.9 °F (6.1 °C). Freezing temperatures occur on an average of only 1.3 days annually. The coldest winter temperature on record was 20 °F (−7 °C) on December 11, 1932, a day on which 1 inch (2.5 cm) of snow also fell. A week-long cold spell in December 1972 caused hard freezes throughout the area, damaging trees and plants and causing some water pipes to break; the temperature dropped as low as 24 °F (−4 °C) at the airport and 20 °F (−7 °C) in Crestmoor, which also reported snow flurries several times that week. There was 1.5 inches (3.8 cm) of snow at the airport on January 21, 1962, with several inches falling in the hills.
September is the warmest month with an average high of 72.7 °F (22.6 °C) and an average low of 55.1 °F (12.8 °C). Temperatures exceed 90 °F (32 °C) on an average of 4.0 days annually. Fog and low overcast are common during the night and morning hours in the summer months, which are generally very dry except for occasional light drizzle from the fog. On rare occasions moisture moving up from tropical storms has produced thunderstorms or showers in the summer. Gusty westerly winds are also common in the afternoon during the summer. The highest summer temperature was 106 °F (41 °C) on June 14, 1961, breaking a record of 104 °F (40 °C) set in June 1960. A high of 105 °F (41 °C) was recorded on July 17, 1988, and a high of 104 °F (40 °C) was recorded on September 1, 2017. Until August 1, 1993, it had never reached 100 °F (38 °C) in August, which is one of the foggier months in the area. Due to thermal inversions, summer temperatures in the higher hills are often much higher than at the airport.
Thunderstorms occur several times a year, mostly during the winter months, but are usually quite brief. Total annual precipitation, most of which falls from November to April, ranges from 20.11 inches (511 mm) at the nearby National Weather Service station at San Francisco International Airport to over 32 inches (810 mm) in the higher hills (according to observations by Gayle Rucker for the Army Corps of Engineers and Robert E. Nylund for the U.S. Geological Survey from 1962 to 1985). Nylund also took temperature observations for several years and published weekly weather reports in the San Bruno Herald from 1966 to 1969, which were included in official reports for the Golden Gate National Cemetery. The annual average days with measurable precipitation is 65.2 days. The most rainfall in a month at the airport was 13.64 inches (346 mm) in February 1998, and the most rainfall in 24 hours was 5.59 inches (142 mm) on January 4, 1982. Nylund reported 6.09 inches (155 mm) in Crestmoor during a 24-hour period in January 1967. Winter storms are often accompanied by strong southerly winds.
The 2020 United States census reported that San Bruno had a population of 43,908. The population density was 7,999.3 inhabitants per square mile (3,088.5/km2). The racial makeup of San Bruno was 33.8% White, 1.8% African American, 1.0% Native American, 32.2% Asian, 2.6% Pacific Islander, 14.8% from other races, and 13.8% from two or more races. Hispanic or Latino of any race were 28.0% of the population.
