Rain season
San Antonio sits on the edge of the Texas Hill Country, where Gulf moisture collides with drier continental air — producing intense, often dangerous rainfall. Spring (April–May) and autumn (September–October) are the wettest periods; summer can be hot and largely dry. Flash flooding is the primary hazard: the Balcones Escarpment to the north funnels runoff rapidly toward the city.
