Open Skies PhotoForecast

Know exactly when the light and weather will be right — hour-by-hour photography scores for golden hour, the Milky Way, and six more styles.

Open Skies tells you exactly when the light and weather will be right for the photo you want to make — hour by hour, for any location.

Instead of a generic weather app, Open Skies scores each hour from 0 to 100 for seven kinds of photography, factoring in cloud cover, wind and gusts, precipitation, visibility, humidity, sun angle, and moon conditions.

SEVEN PHOTOGRAPHY MODES Landscape, Portrait, Street, Wildlife, Astrophotography, Macro, and Fog & Mist. Each mode weighs conditions differently — heavy overcast is a softbox for portraits but flat for landscapes, and dead-calm air is everything for macro.

LIGHT THAT ACTUALLY MATTERS Golden hour, blue hour, and astronomical darkness are calculated from the real sun position at your exact coordinates — not just a fixed offset from sunset.

BUILT FOR ASTROPHOTOGRAPHY Open Skies models the moon the way astrophotographers actually think about it: not just the phase, but the moon's altitude in the sky. A bright moon overhead floods the whole sky, but the same moon near the horizon barely dims the stars while gently lighting your foreground. Conditions right around moonrise and moonset — at the right phase — score highest, and a moon below the horizon means the darkest possible sky.
