August 2025 · phase for each day (UTC)

Best Nights in August


Darkest skies

Aug 21 – Aug 25

Around the New Moon (Aug 23), little moonlight — the best nights for the Milky Way, meteors and faint deep-sky objects.

Sharpest Moon detail

Aug 1 · Aug 16

At the quarter Moons the terminator throws long shadows across crater rims — the best nights to photograph lunar surface detail.

Brightest nights

Aug 8 – Aug 10

Around the Sturgeon Moon (Aug 9), strong natural moonlight for night walks — but it washes out fainter stars.
