How the score works

60% weight

Cloud cover

Averaged over the whole dark window, layer by layer. Low cloud blocks everything; thin high cirrus still lets bright stars through.

40% weight

Moon darkness

A new moon boosts the score. A bright Moon only costs points while it is actually above the horizon in the dark hours, and more the higher it stands.

What you can realistically see from the city

The Moon and the bright planets (Venus, Jupiter, Saturn, Mars when it is close) show up even from a light-polluted centre on a clear night.
Bright stars and constellations are easy. Through binoculars, the Pleiades and the Orion Nebula (winter) still stand out; faint galaxies do not.
The Milky Way is not visible from central Frankfurt; you need a dark site outside the city.

Darkness through the year

From about 31 May to 11 July the sun never gets 18° below the horizon, so the sky never becomes fully dark, even at 2 a.m.
Around the winter solstice you get about 12 hours of full darkness.
Nights with 9+ hours of full darkness: October – February.
The bright core of the Milky Way (in Sagittarius) never climbs more than 11° above the southern horizon from Frankfurt, so it hides behind haze and buildings.
The summer Milky Way through Cygnus is the one to look for: its brightest star, Deneb, passes 85° high.

Stargazing in Frankfurt: questions

When does it get properly dark in Frankfurt?

Between about 31 May and 11 July it never gets fully dark. The longest dark nights, around the winter solstice, give about 12 hours of full darkness. Months with 9+ hours: October – February.

Can you see the Milky Way from Frankfurt?

Not from the city centre. From Frankfurt's latitude the Milky Way's core peaks at only 11° above the horizon, so the band to look for is the summer Milky Way through Cygnus, which passes 85° high on dark nights from July to October. The nearest designated dark-sky place is Sternenpark Rhön, about 107 km away.

Sternenpark Rhön: International Dark Sky Reserve (2014), about 107 km as the crow flies.

What is the best time of year for stargazing in Frankfurt?

For long, fully dark nights: October – February. Around the winter solstice there are about 12 hours of full darkness. Check the score before you go; clouds decide more than the calendar.
