San Jose is located within the
Santa Clara Valley, in the southern part of the
Bay Area in Northern California. The northernmost portion of San Jose touches
San Francisco Bay at
Alviso, though most of the city lies away from the bayshore. According to the
United States Census Bureau, the city has a total area of , making it the fourth-largest city in California by land area (after Los Angeles, San Diego, and
California City). The most serious earthquake, in 1906, damaged many buildings in San Jose as described earlier. Earlier significant quakes rocked the city in 1839, 1851, 1858, 1864, 1865,
1868, and 1891. The
Daly City Earthquake of 1957 caused some damage. The
Loma Prieta earthquake of 1989 also did some damage to parts of the city.
Cityscape San Jose's expansion was made by the design of
"Dutch" Hamann, the City Manager from 1950 to 1969. During his administration, with his staff referred to as "Dutch's
Panzer Division", the city annexed property 1,389 times, growing the city from , absorbing the communities named above, changing their status to "neighborhoods." Sales taxes were a chief source of revenue. Hamann would determine where major shopping areas would be, and then annex narrow bands of land along major roadways leading to those locations, pushing "tentacles" or "finger areas" across the Santa Clara Valley and, in turn, walling off the expansion of adjacent communities. During his reign, it was said the City Council would vote according to Hamann's nod. In 1963, the State of California imposed
Local Agency Formation Commissions statewide, but largely to try to maintain order with San Jose's aggressive growth. Eventually the political forces against growth grew as local neighborhoods bonded together to elect their own candidates, ending Hamann's influence and leading to his resignation. While the job was not complete, the trend was set. The city had defined its sphere of influence in all directions, sometimes chaotically leaving unincorporated pockets to be swallowed up by the behemoth, sometimes even at the objection of the residents. East of the Guadalupe River,
Coyote Creek also flows to south San Francisco Bay and originates on
Mount Sizer near
Henry W. Coe State Park and the surrounding hills in the
Diablo Range, northeast of
Morgan Hill, California. The lowest point in San Jose is below sea level at the San Francisco Bay in Alviso; the highest is . Because of the proximity to
Lick Observatory atop Mount Hamilton, San Jose has taken several steps to reduce
light pollution, including replacing all street lamps and outdoor lighting in private developments with
low pressure sodium lamps, but in 2018 they allowed
LED billboards to shine brightly, adding interference to the night sky in the form of blue light. To recognize the city's early efforts to preserve the night sky, the
asteroid 6216 San Jose was named after the city in 1997. There are four distinct valleys in the city of San Jose: Almaden Valley, situated on the southwest fringe of the city; Evergreen Valley to the southeast, which is hilly all throughout its interior; Santa Clara Valley, which includes the flat, main urban expanse of the South Bay; and the rural
Coyote Valley, to the city's extreme southern fringe. The extensive
droughts in California, coupled with the drainage of the reservoir at
Anderson Lake for
seismic repairs, have strained the city's
water security.
Climate San Jose, like most of the Bay Area, has a
Mediterranean climate (
Köppen:
Csb), with warm to hot, dry summers and cool, wet winters. San Jose has an average of 298 days of sunshine and an annual mean temperature of . It lies inland, surrounded on three sides by mountains, and does not front the Pacific Ocean like San Francisco. As a result, the city is somewhat more sheltered from rain, barely avoiding a
cold semi-arid (
BSk) climate. The highest temperature ever recorded in San Jose was on September 6, 2022; the lowest was on January 6, 1894. On average, there are 2.7 mornings annually where the temperature drops to, or below, the freezing mark; and sixteen afternoons where the high reaches or exceeds .
Diurnal temperature variation is far wider than along the coast or in San Francisco but still a shadow of what is seen in the
Central Valley. "Rain year" precipitation has ranged from between July 1876 and June 1877 to between July 1889 and June 1890, although at the current site since 1893 the range is from in "rain year" 2020–21 to in "rain year" 1982–83. 2020–2021 was the lowest precipitation year ever, in 127 years of precipitation records in San Jose. The most precipitation in one month was in January 1911. The maximum 24-hour rainfall was on January 30, 1968. On August 16, 2020, one of the most widespread and strong thunderstorm events in recent Bay Area history occurred as an unstable humid air mass moved up from the south and triggered multiple dry thunderstorms which caused many fires to be ignited by 300+ lightning strikes in the surrounding hills. The CZU lightning complex fires took almost 5 months to fully be controlled. Over 86,000 acres were burned and nearly 1500 buildings were destroyed. The snow level drops as low as above sea level, or lower, occasionally coating nearby
Mount Hamilton and, less frequently, the
Santa Cruz Mountains, with snow that normally lasts a few days. Snow will snarl traffic traveling on
State Route 17 towards
Santa Cruz. Snow rarely falls in San Jose; the most recent snow to remain on the ground was on February 5, 1976, when many residents around the city saw as much as on car and roof tops. The official observation station measured only of snow.

Downtown San Jose),

Coyote Creek Trail •
Guadalupe River Trail •
Los Gatos Creek Trail •
Los Alamitos Creek Trail •

Several trail systems within the network are designated as part of the National Recreation Trail, as well as regional trails such as the San Francisco Bay Trail and Bay Area Ridge Trail.
Wildlife Early written documents record the local presence of migrating salmon in the Rio Guadalupe dating as far back as the 18th century. Both
steelhead (
Oncorhynchus mykiss) and
King salmon are extant in the
Guadalupe River, making San Jose the southernmost major U.S. city with known salmon spawning runs, the other cities being
Anchorage;
Seattle;
Portland and
Sacramento. Runs of up to 1,000
Chinook or King Salmon (
Oncorhynchus tshawytscha) swam up the Guadalupe River each fall in the 1990s, but have all but vanished in the current decade apparently blocked from access to breeding grounds by impassable culverts, weirs and wide, exposed and flat concrete paved channels installed by the
Santa Clara Valley Water District. In 2011 a small number of Chinook salmon were filmed spawning under the Julian Street bridge. Conservationist Roger Castillo, who discovered the remains of a mammoth on the banks of the Guadalupe River in 2005, found that a herd of
tule elk (
Cervus canadensis) had recolonized the hills of south San Jose east of Highway 101 in early 2019. At the southern edge of San José,
Coyote Valley is a corridor for wildlife migration between the
Santa Cruz Mountains and the
Diablo Range. == Demographics ==
