Watch weather patterns evolve globally, or right down in your neighborhood, in Dark Sky's stunningly smooth map simulations. Pull storms back and forth through time — and into the future — to see what the weather has in store for you.
See a detailed breakdown of current conditions where you're standing, including wind speed and direction, humidity, pressure and visibility. Dark Sky is your own personal weather station.
Dark Sky will deliver precise alerts when rain or snow is about to start wherever you are. Even if you haven't opened the app in days, Dark Sky will know when you're in the path of a storm. Never get stuck in the rain again.
Dark Sky is powered by Forecast, a weather service we built from scratch specifically for the app. As an independent service we aren't beholden to the big guys, allowing us the freedom to innovate and experiment with new ways of analyzing the weather.
