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

12 degrees warmer at arrival

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

Founded 1769

From balmy beaches with a laid-back attitude to a gleaming modern image, San Diego offers much for the tourist to enjoy. Situated on the Southern California seacoast, San Diego is the second largest city in the state, with 1.4 million residents (2020), and has long attracted travelers for its ideal climate, miles of beaches, and location on the Mexican border right across from Tijuana. But there's much more here than surfer culture and a quick hop across the border. A rich maritime and military heritage lives on in San Diego, which is home to the Pacific Fleet of the United States Navy. The city has also become known for its part in the wildlife conservation movement, owing to the presence of the world-renowned San Diego Zoo and Safari Park and the Scripps Institution of Oceanography. Natural scenery abounds from rocky tidepools and seaside cliffs to desert hills and canyons inland.
