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
2 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
Road read
2h 25m on the road

Charleston is the largest and oldest city in the state of South Carolina in the United States of America. Its historic downtown is on a peninsula formed by two rivers, the Ashley and the Cooper, flowing into the Atlantic, and protected from the open ocean by surrounding islands. Charleston was captured in the American Civil War without much property damage, so the historic part of town has buildings that are hundreds of years old. The current downtown skyline, with practically no tall buildings due to the city's height restriction ordinance, is dominated by church steeples and the stunning Arthur Ravenel cable-stay bridge over the Cooper River. The city is a major port on the eastern seaboard of the U.S. and a popular destination for domestic and international tourists.
