Is Tonight Good for Stargazing in San Antonio?

Clear, dark skies tonight (about 1% cloud) with the Moon well out of the way. This is about as good as it gets — from a dark site away from city lights you'll see the Milky Way, faint stars, and any active meteor shower.

READING TONIGHT'S SKY…

How dark is the sky over San Antonio?

Sky class (estimate)Bortle 8 · City sky

Like most large cities, the centre of San Antonio sits high on the Bortle scale (around class 8), so the Milky Way and faint stars are lost to the glow. For dark sky, head well away from the city lights.

Even on the clearest, Moonless night, a bright city sky limits what you can see. For the Milky Way and faint stars from San Antonio, you'll need to travel well clear of the city lights.
