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

Very similar conditions

Both ends of the route are sitting at about the same temperature right now.
