What month does it start to get cool in Austin, Texas?|171950

Trying to fly 2 dogs out of Texas, but the airlines don_t allow it unless the outside weather is under 85 degrees fahrenheit and above 40 degrees fahrenheit.
Really don_t want a red-eye flight. So, what month should be cool enough?

This summer has been hotter than usual. Normally it will start to cool down in September, but chances are it won_t be until mid to late October this year. November and December are generally mild but a cold front could cause it to drop below 40 degrees.

November, MAYBE late October.

Maybe if we are lucky you could do it at the end of October but I would plan on November.
