AUSTIN (KXAN) — Although unseasonably hot weather continues Tuesday and Wednesday, these may be some of Austin’s last 90-degree days of the year as we track an autumn-like change in the weather late this week.
A broad western storm is approaching Texas, bringing mostly cloudy skies and a small rain chance early this week. As the powerful storm clips Texas and sends a cold front our way on Thursday, storms become likely and temperatures drop.
Hottest September on record
Austin-Bergstrom International Airport experienced its hottest September on record with an average mean temperature of 85.6º, beating the previous hottest September of 85.3º set in 2019.

Austin-Bergstrom and Camp Mabry also just recorded their hottest June through September period on record — hotter, even, than 2011.
With nine months in the books, Camp Mabry’s average temperature of 77.5° so far this year ties 2011 as the hottest year on record.
