Cerro de la Silla, whose summit reaches about 1,820 metres above sea level, towers over Monterrey and is on the city's coat of arms. Monterrey is Mexico's industrial capital and among the wealthiest cities in Latin America by output per resident.
The clock: Monterrey keeps UTC−6. It is close enough to Texas that its business day has long tracked the American one, which made Mexico's 2022 abolition of daylight saving genuinely disruptive here.
Monterrey lies at 100.3°W. Its time zone, UTC−6, is built around the 90°W meridian. The 10.3° gap between them means the clock runs roughly 41 minutes ahead of the sun: solar noon arrives at about 12:41 rather than 12:00. The zone holds UTC−6 all year — there is no daylight saving here.
The longest day of 2026 is 22 June, with 13h 45m of daylight. The shortest is 22 December, with 10h 32m. The swing between them is 3h 13m. 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 Monterrey the sun comes up earliest on 10 June at 05:49, while the latest sunset waits until 4 July at 19:36. 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 Monterrey that civil twilight runs about 23 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.
