Sunrise & Sunset Times in San Antonio — March 2025

Sunrise & Sunset in San Antonio During March

March contains the spring equinox around the 20th, when day and night are nearly equal in length in San Antonio. Before the equinox, days are shorter than nights; after it, daylight takes the lead and keeps growing. The rate of change is at its fastest near the equinox — residents can gain three to four minutes of daylight per day. Many regions also shift to daylight saving time in March, moving clocks forward and pushing sunset an hour later.

During March, golden hour in San Antonio lasts approximately 50 minutes each morning and evening. The low sun angle during these periods produces warm, directional light prized by photographers and filmmakers.
