Clear Outside

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.

• ISS pass-over information.

• Automatically provides a forecast for your current location.

• Save favourite locations for easy access.

• Daytime forecasts 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.
