San Antonio's highest temperature on August 21, 2026, will settle six markets, each defined by a temperature band from 99°F or below to 108°F or above.
Resolution depends on the maximum temperature recorded at San Antonio (CLISAT) on August 21, 2026, as reported by The Weather Company. Markets are segmented into ranges: 99°F or below, 100°F to 101°F, 102°F to 103°F, 104°F to 105°F, 106°F to 107°F, and 108°F or above.
