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
11 degrees warmer at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

Frank Lloyd Wright is said to have quipped, "Tip the world over on its side and everything loose will land in Los Angeles," a quote that has since been repeated both by those who love and hate L.A. The "City of Angels" is home to people who hail from all parts of the globe and an important center of culture, business, media, and international trade. However, it's most famous for being a major center of the world's television, motion picture, and music industry, which forms the base of the city's status and lures visitors for its show business history and celebrity culture. Visitors are also drawn to Los Angeles for its Mediterranean climate and numerous beaches, which gave birth to California's famed surf culture.
