Cairo, Egypt • 30.47° N, 31.67° E

Sunrise & Sunset in Cairo Today

Q: What is the exact solar noon in Cairo?

Solar noon in Cairo occurs when the sun crosses the local celestial meridian (31.67° E) and reaches its maximum angular elevation above the horizon. Because Cairo operates on Africa/Cairo, solar noon typically occurs around mid-day, adjusted for the seasonal Equation of Time.

Q: How does atmospheric refraction affect sunrise and sunset in Cairo?

At latitude 30.47°, standard atmospheric refraction lifts the apparent image of the solar disc by approximately 34 arcminutes (0.566°). Combined with the sun’s 16 arcminute semidiameter, official sunrise and sunset are calculated when the center of the true solar disc is 90°50′ from the zenith.

Q: When are the golden hour shooting windows in Cairo?

The morning golden hour begins at sunrise and lasts for approximately 60 minutes as the sun climbs to 6° solar elevation. The evening golden hour begins 60 minutes before sunset and concludes as the sun dips below the horizon, providing warm, diffused lighting ideal for outdoor photography.

Welcome to the definitive solar ephemeris for Cairo (Egypt), situated at geographic coordinates 30.4744° N latitude and 31.6657° E longitude within the Africa/Cairo timezone. Because Cairo is positioned at subtropical coordinates, daylight duration fluctuates predictably throughout the solar year—reaching its maximum duration during the June solstice and its annual minimum near the December solstice.

All timestamps displayed below are computed using client-side spherical astronomy algorithms derived from the U.S. Naval Observatory Astronomical Almanac 2024 and the NOAA Solar Calculator, accounting for standard 34-arcminute atmospheric refraction and 16-arcminute solar semidiameter at sea level.
