Antelope Canyon's famous light beams appear when the sun climbs high enough to pour directly through the narrow slots in the canyon roof, which means late spring through early fall, roughly March to October, with the strongest, most reliable beams in late spring and summer. The window within the day is just as narrow: beams form around midday, roughly 11 a.m. to 1 p.m., when the sun is nearly overhead. Outside those hours the canyon is still beautiful, swirls of orange, rose, and purple stone, but the shafts of light belong to noon. Dust kicked up (sometimes deliberately, by guides) is what makes the beam visible; on still days it can be faint.
