Factors Affecting Snow in San Antonio

When thinking about San Antonio’s weather, it’s important to understand the factors that tend to limit the city’s snowfall each year.

San Antonio’s geographical location plays a key role in its infrequent snow. It’s located at a latitude where cold air masses from the north meet warm, moist air brought up from the Gulf of Mexico.
