Sunrise & Sunset in Honolulu Today
Welcome to the definitive solar ephemeris for Honolulu (USA), situated at geographic coordinates 21.3099° N latitude and -157.8581° E longitude within the Pacific/Honolulu timezone. Because Honolulu 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 Honolulu?
Solar noon in Honolulu occurs when the sun crosses the local celestial meridian (-157.86° E) and reaches its maximum angular elevation above the horizon. Because Honolulu operates on Pacific/Honolulu, solar noon typically occurs around mid-day, adjusted for the seasonal Equation of Time.
Q2.How does atmospheric refraction affect sunrise and sunset in Honolulu?
At latitude 21.31°, 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 Honolulu?
The morning golden hour spans the Sun’s climb from 0° to 6° elevation, with the evening window covering the reverse crossing. Its duration varies with latitude and season rather than lasting a fixed 60 minutes.
