Top-ranked Texas vs. No. 5 Georgia in college football is only part of Austin's big weekend featuring Formula 1 and no rooms at the inn.

Austin anticipates a warm October weekend with highs in the mid-80s, and the workweek may see temperatures near 90 degrees. Despite a slim chance of a stray shower, the forecast remains mostly dry.

As Austin hotels book up, many F1, UT and UGA fans are looking to Airbnb for a place to stay this weekend. About half of all listings are already booked, according to short-term rental company Airbnb.
