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

3 degrees warmer 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. It is the capital of Texas and a college town, and also a center of an alternative culture away from the major cities on the US coasts, though the city is rapidly gentrifying with its rising popularity. Austin's attitude is commonly emblazoned about town on T-shirts and bumper stickers that read: "Keep Austin Weird." Austin is also marketed as the Live Music Capital of the World due to the large number of venues.
