San Antonio Weather

The city of San Antonio is the seventh most populated city in the country and yet it is not the most populated one in Texas. The weather in San Antonio qualifies as humid sub-tropical though most people would have thought it was arid. The summers in San Antonio are hot. In fact they can be scalding hot while the winters tend to be more on the mild side. Most people do not realize this but it actually snows in San Antonio and it does so almost every year but not that much. San Antonio weather is influenced by the Gulf of Mexico and its latitude in the south of the United States. Even with those influences, the weather in the city can be predictable.

How Hot Is It?

It is not that the temperatures can reach extreme numbers; in fact the hottest temperature ever is only 111 Fahrenheit (44 Celsius). The problem is that the temperatures are hot all the time.
