What is Solar Noon?
Solar noon is the moment when the sun crosses the local meridian and reaches its highest elevation angle above the horizon. At solar noon in San Antonio, the sun is due south and shadows point due north.
Why Solar Noon Differs from 12:00 Clock Time
San Antonio is located at longitude -98.49, which places it 8.5 degrees offset from the nearest time zone meridian. Every degree of longitude corresponds to 4 minutes of solar time, so the offset from clock noon can be significant. A second factor is the equation of time: Earth's elliptical orbit means solar days vary by up to 16 minutes throughout the year, shifting solar noon earlier or later relative to clock time.
Solar Noon and Photography
Solar noon in San Antonio (today: 13:34) produces the most direct, overhead light of the day. This creates short, harsh shadows that are generally unflattering for portraits and landscapes. However, the hours immediately around solar noon can work well for architectural photography where straight-down shadows reveal texture. For the best natural light, work during golden hour: from 07:13 onward in the morning, or approaching 19:55 in the evening.
