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

The wonderful tropical island is very quiet and mostly residential. Key Biscayne Island, which is south of South Beach, is the first island of the Florida Keys. Beaches are spectacular, the landscaping is lush and waterfront activities are plenty. Some consider it the best area to feel like you are in the islands while being in Miami.
