The sun and the clock in Tijuana (2026)
Tijuana lies at 117.0°W. Its time zone, UTC−8, is built around the 120°W meridian. The 3.0° gap between them means the clock runs roughly 12 minutes behind the sun: solar noon arrives at about 11:48 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 48 minutes and pushing solar noon to 12:48.
The longest day of 2026 is 22 June, with 14h 17m of daylight. The shortest is 22 December, with 10h 1m. The swing between them is 4h 17m. At this latitude the seasons are visible in the clock, but never dramatic.
The earliest sunrise and the latest sunset do not land on the longest day. In Tijuana the sun comes up earliest on 13 June at 05:40, while the latest sunset waits until 1 July at 19:59. The equation of time is what separates them: the Earth's elliptical orbit and axial tilt move solar noon back and forth by several minutes over the year.
The sky stays usably light for a while after the sun goes down. In Tijuana that civil twilight runs about 25 minutes at the equinox.
Every figure in this section is computed from the city's own latitude, longitude and IANA time zone using NOAA solar algorithms (Spencer, 1971), accurate to about ±2 arcminutes below 65° latitude.
