Reliable weather forecasts for astronomers with an emphasis on cloud cover. 

Features include:

• Seven day hourly forecasts, updated hourly. 
• Low, medium, high and total cloud cover. 
• Moon rise/set times and phase. 
• Sun rise/set and transit. 
• Civil/nautical/astronomical darkness. 
• International Space Station (ISS) pass-over information. 
• Location search automatically provides a forecast for your location. 
• Save favourite locations for easy access. 
• Covers daytime too so also useful for solar observers/imagers. 

Updated hourly. Frequent hourly updates are important because often the clear spell between showers provides excellent seeing and 30-minutes under a clear sky with a grab-&-go telescopes is pure gold! 

Did you notice the ISS pass-over information? The times are precisely calculated for your location and displayed alongside the cloud forecasts so it has never been easier to observe. It is our favourite feature :-) 

Also includes regular weather data (wind, rain, frost, temperature, dew point, etc) so perfect for those wanting a detailed weather forecast, without cutesy graphics. 

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