Guadalupe County

Guadalupe County is ninety miles inland from the Gulf of Mexico in south central Texas and is bounded by Comal, Hays, Caldwell, Gonzales, Wilson, and Bexar counties. Cibolo Creek forms the border between Guadalupe and Bexar counties, and the San Marcos River separates Guadalupe and Caldwell counties. Seguin, the county seat and largest town, is on Interstate Highway 10 and U.S. Highway 90, twenty-five miles southwest of Austin and eighteen miles northeast of San Antonio. The county's center lies near Seguin at approximately 29°35' north latitude and 97°57' west longitude. The county covers 713 square miles of flat to rolling terrain with local depressions and escarpments, and its elevation ranges from 450 to 800 feet above sea level. The northwestern section, near the border with Comal and Hays counties, is part of the Blackland Prairie; the rest of the county lies in the Upper Coastal Plain. Soil types vary from dark, calcareous clay in the northwest to fine, sandy loam in the southeast. Vegetation consists primarily of mesquite, scrub brush, and grasses in drier areas of the county, while water-tolerant hardwoods and conifers flourish near creeks. The area has a mild subtropical climate, with temperatures ranging from an average high of 96° in July and an average low of 42° in January. The annual rainfall in the county averages 33 inches, and the growing season averages 275 days.
