Welcome to San Antonio

Named for Saint Anthony of Padua,
San Antonio is the seat of Bexar County in south Texas. It is about 75 miles southwest of Austin, Texas’ capital city; 190 miles west of Houston; and 250 miles south of the Dallas/Fort Worth area. San Antonio is the seventh-largest municipality in the U.S. It encompasses 467 square miles, and more than 1.3 million people call the city home. Often called “Military City USA,” San Antonio has one of the nation’s largest active and retired military populations. Joint Base San Antonio-Sam Houston is one of the Army’s oldest installations and is home to many historic buildings.

The Alamo, San Antonio’s first mission, served as a way station between east Texas and Mexico for a century before it fell in the Battle of the Alamo. Fiesta, San Antonio’s signature event, is 11 days long in April. It originally ­commemorated the victory over the Mexican army in the Texas Revolution but has since grown to be inclusive of the diverse local ­cultures. Today, the Alamo is the Shrine of Texas Liberty — often considered a must-see for most visitors and newcomers. But, the Alamo is only one of five historic missions in San Antonio. At San Antonio Missions National Historic Park, south of downtown, visitors can catch a glimpse of colonial days and the Spanish ­influence in the early 1700s at one of the four other ­missions Spanish explorers established along the San Antonio River. Today, parishes within the ­missions remain active with church services, weddings and funerals connecting the past and the present.

With more than 300 days of sunshine ­annually, San Antonio boasts a mild climate that is ­comfortable year-round. Nearly 50 miles of developed greenway trails that connect parks along the Salado and Leon creeks and the San Antonio and Medina rivers offer residents a slew of outdoor recreation options. San Pedro Springs Park, second-oldest municipal park in the nation, features the MacFarland Tennis Center and a pool filled by the springs. San Antonians play a lot of golf — there are more than 50 golf courses in the city.

San Antonio is on the southern edge of the Texas Hill Country. Many of the nearby towns were settled by German and Eastern European immigrants when Texas was freshly independent from Mexico. Hill Country today has a unique culture that blends traditions, cuisine and architecture — from the old-world charm of New Braunfels to “Cowboy Capital of the World” Bandera.

From missions to museums, the local history, art, architecture, music and outdoor spaces ­display a blend of Mexican-American traditions, Spanish heritage and Texas pride that converge in modern San Antonio.


Before the establishment of the Spanish ­missions, Native American tribes had long been associated with the San Antonio area. Coahuiltecans were hunters and gathers ranging throughout south Texas and northeastern Mexico, following the seasonal availability of food. Conflicts between the Coahuiltecans
and Spaniards are documented beginning in the 16th century. For the Spaniards, the acculturation of the natives was a major means for securing their claim to vast lands in North America. With few soldiers or settlers, Spain’s claim to these areas in the face of encroachment by France and England depended on the success of the missions. Presidios, a system of frontier military outposts, were established nearby the missions to protect Spain’s expanding territory.

San Antonio de Bexarunder Spain and Mexico

Spanish expeditions in 1691 and 1709 explored the area and named the San Antonio River and San Pedro Creek. Beginning in 1718, five Spanish missions were established near the head of the river to evangelize the Native Americans of the region. In 1718, San Antonio de Bexar ­Presidio was founded. Early the next year, the king of Spain approved the Marques de San Miguel de Aguayo’s proposal to transport ­families from the Canary Islands to populate the province of Texas. By March 1731, 15 families arrived and the villa of San Fernando de Bexar was founded between the San Antonio River
and San Pedro Creek, east of the presidio. It
was the first chartered civilian settlement in Texas and served as the provincial capital from 1773 to 1824.

The natives were relatively willing recruits for the missionaries as their population was decimated by European disease and they faced an ongoing struggle against encroaching nomadic tribes from the north and south. The natives found food and refuge in the missions in exchange for a strictly regulated mission life that included their labor and their submission to religious conversion.

Increasing hostility from the mission natives’ traditional enemy, the Apache, and later the Comanche, coupled with inadequate military support caused the communities to retreat behind walls. In 1792, all missions are closed by order of the Spanish government, and in 1793 the abandoned Mission San Antonio de Valero, later called the Alamo, became a barracks for Spanish soldiers from Alamo de Parras, Mexico.

From 1811 through the mid-1830s political and military upheavals hindered growth in San Fernando, and when hostilities between Texas and the Mexican government erupted in 1835, it became a base of operations and battlegrounds in the siege of Bexar in December and the battle of the Alamo in March 1836.

Era of Texas Independenceand Early Statehood

From 1836 to 1845 the city was a part of the Republic of Texas until being annexed into the Union. In 1837, San Fernando was renamed San Antonio and became the seat of Bexar County. The Mexican War (1845 to 1848) led to Mexico ceding Texas, California, New Mexico and
most of Arizona to the United States for $18,250,000. After Texas entered the union in 1845, San Antonio grew as a servicing and ­distribution center for the western movement of the United States.

San Antonio during the Civil Warand Reconstruction

Texas had been a part of the United States for 15 years before Texas formally seceded on March 2, 1861, and like the rest of the country, it was divided with conflict and controversy. Some Texans supported the Union — Gov. Sam
Houston refused to declare loyalty to the ­Confederacy. He was removed from office by the Texas secession convention.

In 1861, a local militia forced the surrender of the federal arsenal at San Antonio even before the state seceded. San Antonio then served as a Confederate depot, and several Confederate units were formed.

San Antonio Becomes a Modern City

After the Civil War, San Antonio was the southern hub and supplier of the cattle trail drives. It was the starting point for the Chisholm Trail, a cattle route from Texas to Kansas. The cattlemen who drove the longhorns north to Kansas railheads launched the legend of the American cowboy. The city prospered serving the border region and the Southwest as a center for distribution, mercantile and the military. In 1873, John Dobbin was appointed ­Marshal and transformed the police force from a ­frontier, cowboy-type group into an organized, ­uniformed police department. When barbed wire was introduced to San Antonio in 1876, its widespread use led to “fence cutting” and range wars. Fort Sam Houston was established in 1876. Railroad service reached the city in 1877, and street car operations began too. Two years later Western Union brought telephone service to San Antonio, and in 1883, electricity was extended to the city center. Automobiles began to arrive in San Antonio by 1899. The Gunter Hotel in San Antonio served as headquarters in Texas for the construction of the southern transcontinental highway named Old Spanish Trail during the 1920s.

The 20th century brought more military bases to the greater San Antonio, with a strong Air Force presence. San Antonio celebrated its 250th birthday in 1968 when it held the World’s Fair, HemisFair ’68. The Tower of the Americas was the theme structure of the fair, and today it
is among the tallest observation towers in the U.S. with a lounge and revolving restaurant
at the top.

Weather and Climate

San Antonio’s main climate influences are tropical and desert, it lies near the western edge of the humid subtropical climate zone. The ­temperature has mild fluctuations from summer to winter, and humidity varies depending on the winds. The average annual temperature is 69.1 degrees. July and August are usually the warmest months of the year with an average temperature of 95 degrees. Most precipitation falls in the late spring or early fall. During the winter, San Antonio experiences a few sub-freezing nights but snow is rare.

Local Hazards

Natural disasters affect thousands of people every year, and every second counts in a disaster, so planning and preparation can be lifesavers. Know what your risks are and prepare to protect yourself, your family and community.

Flash Floods

San Antonio is a part of “Flash Flood Alley.” It is one of the most flash-flood-prone regions in North America. A flash flood watch is issued when flash flooding is expected to occur within six hours after heavy rains have ended. A flash flood warning is issued for life- and property-threatening flooding that will occur within six hours. During a flash flood watch or warning, stay tuned to local radio or TV stations or a National Oceanographic and Atmospheric Administration (NOAA) Weather Radio for further weather information.

If you are outdoors during a rainstorm, seek higher ground. Avoid walking through any floodwaters — even water 6 inches deep can sweep you off your feet. If you are driving, avoid flooded areas. The majority of deaths in flash floods occur when people drive through flooded areas. Roads concealed by water may not be intact. Water only a foot deep can ­displace a vehicle. If your vehicle stalls, leave it ­immediately and seek higher ground. Rapidly rising water can engulf a vehicle and sweep it away.

Sun Exposure

Some exposure to sunlight is good, even healthy, but too much can be dangerous. Broad-spectrum ultraviolet (UV) radiation, listed as a known carcinogen by the National Institute of Environmental Health Science, can cause ­blistering sunburns, as well as long-term ­problems like skin cancer, cataracts and immune suppression. Overexposure also causes ­wrinkling and premature aging of the skin.

Cloud cover reduces UV levels, but not ­completely. Depending on the thickness of the cloud cover, you can still burn on a cold and dim day, so be prepared with sunglasses, sunscreen, long-sleeved garments, wide-brimmed hats and a parasol.


While more likely at certain times of year, thunderstorms can happen anytime. A severe thunderstorm can knock out power, bring high winds, lightning, flash floods and hail, and turn into a twister in seconds. Pay attention to storm warnings. Remember the rule: “When thunder roars, head indoors.” Once inside, avoid ­electrical appliances, plumbing fixtures and use only a cordless telephone in an emergency. Unplug your desktop computer. Do the same with other plugged-in electronics or use surge protectors. The National Weather Service recommends following the 30/30 Rule: People should seek shelter if the “Flash-to-Bang” delay — length of time in seconds from the sight of the lightning flash to the arrival of its subsequent thunder — is 30 seconds or less. and remain under cover for 30 minutes after the final thunderclap.

Tornadoes can develop quickly, with minimal warning, so it is important to have a plan in place before they occur. If a tornado watch is issued, weather conditions favor the formation of ­tornadoes, such as during a severe thunderstorm. A tornado warning is issued when a tornado funnel is sighted or indicated by weather radar. You should take shelter immediately during a tornado warning.

Know where the safest place of shelter is in your home — a basement, or an inside room on the lowest floor (like a closet or bathroom) if your home does not have a basement. Avoid windows and get under something sturdy, like a heavy table, and cover your body with a blanket or mattress to protect yourself from flying debris.
