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

1 hour earlier

The destination clock does not match departure time, so double-check hotel check-in windows and late arrival plans.

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.

Road read

3h 25m on the road

Use the two city cards together: check the sky where you start, then compare it with the local time and temperature at arrival.
