Best Time to Stargaze Tonight
Dark sky hours only help if the clouds cooperate. Match the moonless window to the clearest forecast stretch.

What “best time” means
The best hour is usually after astronomical twilight ends, before moonrise (or after moonset), and inside a low-cloud stretch on the forecast. Bright planets can work earlier in twilight. The Milky Way and faint structure need true dark plus darker skies.
Step-by-step
- Open Dark Sky Window for your pin. Note astronomical night start and the longest moonless gap.
- Open Stargazing Weather. Find the clearest hours that overlap that dark gap.
- Read Tonight Score. If the label is Skip, pick another night from the 7-night outlook instead of forcing a drive.
- If city glow washes the sky even when clear, move the pin with Dark Sky Finder.
FAQ
Is midnight always best? No. A bright Moon or a cloud bank at midnight can make 21:00 or 03:00 better.
What if dark hours and clear hours barely overlap? Take the overlapping hour. A short clear dark window beats a long cloudy one.
Do tropics change this? Near the equator, nights are shorter year-round and dew often rises after midnight. Prefer the early dark stretch when humidity climbs late.
Common mistakes
- Planning only by sunset, not astronomical twilight.
- Ignoring moonrise while chasing “clear” skies.
- Using home weather for a darker inland site.
