How long is the daylight duration in Flagstaff across different seasons?

At latitude 35.20°, Flagstaff experiences temperate seasonal variations. Daylight stretches to approximately 14–15 hours during mid-summer and contracts to roughly 9–10 hours during mid-winter.

When are the Golden Hour and Blue Hour in Flagstaff?

The morning Golden Hour begins at sunrise and lasts for approximately 45–60 minutes, while the evening Golden Hour starts about an hour before sunset. The Blue Hour occurs immediately following sunset (and before dawn) during civil twilight when the sun is between 0° and 6° below the horizon, creating vivid deep blue and indigo skylines across Flagstaff.

When does Solar Noon occur in Flagstaff?

Solar Noon in Flagstaff is the exact astronomical instant when the sun crosses the local meridian (-111.65° longitude) and reaches its maximum daily elevation. Depending on the time of year (the Equation of Time) and whether daylight saving time is active, Solar Noon generally falls between 11:45 AM and 1:30 PM in the America/Phoenix zone.

How long does civil twilight last in Flagstaff?

In Flagstaff, civil twilight typically lasts between 25 and 45 minutes after sunset. Because the angle at which the sun sinks below the horizon depends on latitude (35.20°), twilight duration increases in the summer months and is longer than in equatorial regions.

Geographical Solar Characteristics

Solar Profile & Seasonal Cycles in Flagstaff

Positioned at 35.1983° latitude and -111.6513° longitude, Flagstaff operates under the America/Phoenix time standard. The local solar trajectory is determined by Earth's axial tilt relative to Flagstaff's geographic latitude:

Hemisphere & ZoneNorthern Hemisphere • Temperate Zone

Longest daylight occurs around June 21; shortest daylight occurs around December 21.

Atmospheric Refraction Lift+34 Arcminutes (~0.566°)

Atmospheric bending causes the sun to become visible approximately 2.5 to 3.5 minutes prior to true geometric sunrise in Flagstaff.

Solar Noon VarianceEquation of Time Drift

Depending on the time of year, true astronomical midday in Flagstaff deviates from clock midday by up to ±16 minutes due to orbital eccentricity.

Cinematography & Photography Protocol

Golden Hour & Blue Hour Photography Windows in Flagstaff

For landscape photographers, videographers, and creators in Flagstaff, the hour surrounding sunrise and sunset provides the most flattering, diffuse natural lighting:

Golden Hour (Warm Spectrum)Sun +6° to 0°

Light rays travel through extensive atmospheric air masses, scattering high-frequency blue photons and bathing Flagstaff's skyline and landscapes in warm amber, gold, and terracotta hues with long, soft shadows.

Blue Hour (Indigo & Cobalt)Sun 0° to -6°

Occurring during civil twilight, Chappuis ozone absorption filters longer red wavelengths, producing balanced cobalt twilight skies that contrast against the warm artificial architectural lighting of Flagstaff.
