Austin Heatwave Persists: Fall Arrives, But Summer Stays
31 Aug
Summary
- Austin will experience continued 100-degree days into September.
- Rain chances are limited early in the week, with slight improvement possible.
- September's average high temperature remains in the mid-90s.

Meteorological fall arrives in Austin this Tuesday, but residents should still prepare for summer-like temperatures. The city is expected to experience more days reaching 100 degrees Fahrenheit throughout September. While the immediate forecast shows a slight easing of heat to the upper 90s, a modest improvement from recent intense heatwaves.
Rain chances are slim early in the week, with a weak disturbance from the Gulf of Mexico potentially bringing scattered showers closer to the coast, with only limited inland impact expected. Any storms that do develop could include brief downpours and gusty winds.
Looking ahead, a more significant pattern shift, potentially bringing cooler temperatures and more widespread rain, might occur by the following weekend. However, September's outlook favors above-normal temperatures for Texas, indicating a prolonged period of warmth before a true fall transition.
