How does the Moon affect meteor showers?
Moonlight brightens the sky and hides the fainter meteors in a shower. The more of the Moon that is lit, and the longer it is above your horizon during the shower's best hours, the fewer meteors you will notice. Bright meteors still show.

Why the Moon matters
Most meteors in a shower are faint. Against a dark sky, you see the faint ones as well as the bright ones. Moonlight lifts the brightness of the whole sky, so the faint meteors drop below what your eyes can pick out. The shower is just as active; you see a smaller share of it. Bright meteors and the occasional fireball still stand out.

Phase is not enough: is the Moon up?
What hides meteors is a Moon that is lit and above the horizon while you watch. The phase tells you how much is lit. Moonrise and moonset tell you when it is in your sky.
Many showers produce more visible meteors after midnight, as the shower's radiant climbs higher. A Moon that sets in the evening therefore often leaves the best hours dark.
- Near first quarter the Moon sets around midnight. The hours after moonset are Moon-free.
- Full Moon: up all night, rising near sunset and setting near sunrise. It gives the strongest interference.
- Waning Moon (shrinking toward New Moon): rises later each night. The evening hours before moonrise are Moon-free.
How to watch with the Moon up
- Wait for moonset or watch before moonrise, when the shower's hours allow it.
- Keep the Moon out of your view. Put it behind a building, a hill or trees, and face a darker part of the sky. Meteors can appear anywhere overhead, not only near the radiant.
- Give your eyes time. Let them adjust to the dark and avoid white light. Your eyes need the dark even with the Moon up.
- Go for the bright ones. On a moonlit night, the bright meteors are the ones you will catch, so a shower known for bright meteors holds up better.
What The Star Window shows
Each Go, Marginal or Skip verdict is based on a conditions score. The score compares the forecast cloud, Moon interference and how dark the sky gets as the Sun sets for each place's window. Local light pollution is not in the score.
The site does not predict how many meteors you will see.

Questions and answers
Can you see meteors during a full Moon?
Yes, but fewer. The bright ones still show; the faint ones are lost in the moonlit sky.
Is New Moon always the best time for a meteor shower?
It removes moonlight, but not cloud, haze or city light. A shower peak near New Moon still needs an open sky over a dark site.
Does a crescent Moon matter?
Less than a bright Moon, and a waxing crescent sets early in the evening. Check moonset for your location against the hours you plan to watch.
Should I look toward the radiant?
You don't need to. Meteors can appear anywhere in the sky. Face a dark part of the sky, away from the Moon and any city glow.
Does The Star Window's verdict include the Moon?
Yes. The conditions score counts Moon interference in your window, along with forecast cloud and how dark the sky gets as the Sun sets.
