San Antonio weather facts every pet owner should know
- San Antonio's average high hits 96.0F in August, well past the 90F danger line, so summer dog walks belong at sunrise.
- From June through September, average lows sit between 69.6F and 74.9F, so even late evenings often land in the above-77F caution zone once humidity is factored in.
- The city has seen both 111F (September 5, 2000) and 0F (January 31, 1949), so a light dog coat is worth owning even in South Texas.
- San Antonio averages just 0.2 inches of snow a year, so the paw hazards here are hot pavement and summer asphalt, not ice melt.
