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.

“Space City” · Founded 1836

Houston is a sprawling port city in Southeastern Texas. An oil boom and continuing international immigration has brought explosive growth to the city, and it is now the fifth largest metropolitan area in the United States and the most diverse large city since 2021. While at first glance, the city appears to be a 9-5 central business district surrounded by a sea of suburbs and strip malls, there are many hidden gems to be discovered. === Welcome World Cup fans === Games will be played at NRG Stadium on the south side of Houston The best way to get to the stadium on game day is to use MetroRail trains (red line to NRG Stadium/Astrodome). Fare cards can be purchased at kiosks at train platforms and cost US$1.25 per ride The best hotels for football fans are downtown or near the medical center (both areas have easy access to MetroRail).
