About the San Francisco → Los Angeles route
The route from San Francisco, United States to Los Angeles, United States covers roughly 559 kilometres in a southeast direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 1.6 hours. Both cities sit in the northern hemisphere, so the seasonal direction of daylight (longer days in June, shorter in December) matches between origin and destination.
San Francisco is in the temperate zone. Day length varies by four to six hours between summer and winter, so the season of your trip materially affects available morning and evening light. Los Angeles is in the subtropics. Day length varies by roughly two hours between summer and winter; light remains a reliable circadian cue most of the year.
