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.

For long drives, weather on day two can matter just as much as conditions at departure, so check the whole travel window rather than only the first day.

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

24 degrees warmer at arrival

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

Road read

15h 55m on the road

This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.
