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
8 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
50h 45m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.

Sitka is a city of about 9,000 on the Pacific Ocean coast of Baranof Island in Alaska. First settled by Tlingit Aboriginal people, Sitka also has history as a Russian settlement, established in 1799 by Alexander Baranoff of the Russian American Company, which became the Russian capital of Alaska. In 1867, when Russia sold Alaska to the US, the transfer ceremony took place on Castle Hill at Sitka on October 18, a day celebrated as Alaska Day. Sitka now attracts about a quarter million visitors a year.
