Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
Time zone
Same local time
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
4 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

Full guide →“City of the Violet Crown” · Founded 1835
Austin is a city of about 1,054,000 (2026) surpassing Fort Worth to become the 4th most populous city in Texas. It is on the southeast edge of the Hill Country region of Texas, making it the fourth-largest city in the state and the 11th-largest in the country.

Austin is also marketed as the Live Music Capital of the World due to the large number of venues.
