Budget approximately $11 for fuel to cover the distance between these two Pacific Coast locations. You will primarily navigate via D Street, Lakeville Street, and US 101 South.

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
5 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
1h 44m on the road
Use the two city cards together: check the sky where you start, then compare it with the local time and temperature at arrival.
