Why Clearoutside?
Updated hourly, because frequent updates matter! Often the clear spell between showers provides excellent seeing, and 30 minutes under a clear sky with a grab-and-go telescope is pure gold.

Our favourite feature? The ISS pass-over information is precisely calculated for your location and displayed alongside cloud forecasts, making it easier than ever to catch the station overhead.

No cutesy graphics - just detailed, reliable weather data presented clearly for serious observers.

We've had a lot of fun building and testing Clear Outside and are keen to develop it further. If you find it useful or have suggestions, please let us know!
