4:30 PM CDT Update: No more calls, please, we have a winner. Today is the hottest August day ever in the Austin daily climate history which dates back to 1898. The 112° temperature at 2:26 pm was the highest ever in August and tied for the highest all-time temperature (see below). It also smashed the previous record for the date, set in 1924 and tied in 1990, by 8°.
The high temperature of 110° at San Antonio not only crushed the daily record, set in 1940, by 9°, it also broke the August record by 2°. The all-time record at San Antonio was 111°, also on Sept. 5, 2000. San Antonio climate records began in 1886.
While Hurricane Irene has been hogging the limelight, the record rampage of 100° temperatures goes on in Texas. The high of 110° at Austin on Saturday (August 27) tied the all-time August heat record, and the current temperature (3 pm CDT) has at least tied the record again. This raises the annual count of 100° days to date to 73, which is 4 more than the previous record.
The all-time high temperature at Austin was 112° on Sept. 5, 2000.
