On average, August is Austin’s hottest, driest month of the year. The average temperature runs around 99 degrees for a solid two weeks from August 1st thru August 14th. This year, we only were above average on the 1st with a high of 101 degrees.

We did hit 100 degrees two more times since then on the 26th and on the 31st. However, a majority of the month was spent at, or slightly below, seasonal averages. This brings our annual total to just 4 triple digit days.
