About this app

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.

I think this is a very useful tool and I use it all the time. As a person involved in the hobby of astrophotography, it has all of the information I need at a glance without cartoony pictures and fancy layouts. It lays information out in an organized fashion. I have used the Clear Outside website many times before and the app has continuity with that so it reads the same and I can adjust the data displayed in the same way, which is great.

Initially, great for weather data. Has no settings to make changes, or to delete saved locations. Use it for current location only. Don't save any locations, as you will not be able to get rid of them, or make corrections in Lat / Long. There is no way to get rid of or update home location in UK. I'm using Samsung, Android tablets and phone. The app has not been updated since 2015, and I wouldn't hold my breath waiting for one. More than likely will uninstall.

A very useful tool, but lacks a few critical details. A legend of sorts would be nice(is the wind in mph or km/s? Who knows!) it would also be nice to be able to set units to your preference. I know SI is Celsius, but for the air temperature, Fahrenheit is the superior unit. The saved location function is un-intuitive, but if you are willing to use your latitude and longitude, it does work well enough. Free is nice, but I would be willing to pay for a more polished app.
