Sunrise & Sunset in Lisbon Today
Welcome to the definitive solar ephemeris for Lisbon (Portugal), situated at geographic coordinates 38.8823° N latitude and -8.9793° E longitude within the Europe/Lisbon timezone. Because Lisbon 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.

Frequently Asked Questions
Q1.What is the exact solar noon in Lisbon?
Solar noon in Lisbon occurs when the sun crosses the local celestial meridian (-8.98° E) and reaches its maximum angular elevation above the horizon. Because Lisbon operates on Europe/Lisbon, solar noon typically occurs around mid-day, adjusted for the seasonal Equation of Time.
Q2.How does atmospheric refraction affect sunrise and sunset in Lisbon?
At latitude 38.88°, 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.
Q3.When are the golden hour shooting windows in Lisbon?
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.
