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.

NO LONGER ACCURATE
Hi there folks.
I used to use Clear Outside as my default app for astronomical weather, but in recent months it seems to be completely inaccurate. For instance tonight (2Mar), CO is showing between 60 - 100 pc cloud cover while BBC Weather and the Met Office are both indicating a clear night for observing.
Can you look at this and perhaps re-jog your algorithms? Cheers.
Good app with a serious flaw
Whilst Latitude can be edited in Locations, Longitude can't, meaning a precise location cannot be entered.
Perfect
Just what is needed to plan for the evening and morning observations. Clear, easy to use, shows all the relevant factors influencing visibility.
Silly comments about Devon being the default location miss the point that users can set their home location to their liking, including accurate longitudes and latitudes.
One brilliant app by one brilliant company
App and Web differ
I am looking at the 14 15 16 February 2023 and the predicted sky cover results are very different. I cannot attach screen shots but happy to email. So which if either are correct? Location is Helmsley N Yorks.
Really annoying defaulting to developers location!
It's a great app as a photographer, it shows good detail on cloud cover and likely conditions, and generally has been pretty reliable. It's a solid gold 5 star app, except...
...except the opening 'home' page is for the developers location in Devon. And there's no way to change it. I don't use the app enough to remember I have to click 'current location' at the bottom to show me a different location. I really don't understand. It feels bad to moan about a free app that I really appreciate, but it's really annoying nonetheless and you'd think it'd be an easy fix.
Not accurate at all
And for gods sake, sort out the location on the opening home page!
Why default to Devon!
This seems like a very basic flaw, and the home page should show the current location. How many people in the world are going to want Devon as their default location? The default should be current location unless a user specifies a different location.
Also the location page isn’t very accurate, it picks towns/cities a long way from the actual place I want to pick. Most astronomers are going to visit darker skies, so naturally that will be away from large populations. Having the location search only find large towns & cities isn’t helpful. Examples looking for Edale in the Peak District comes up with Manchester, trying Monyash defaults to Bakewell
Useless for custom locatioms
Fine if you only use the location it’s detected. If you try to search for other locations they either don’t come up, or come up,with the right name but totally wrong coordinates.
Horrible interface
Never shows the right location (eg. I select london from search result and it shows manchester’s forecast).
Also crashes abruptly.
Kind of ok
Mostly works well. Quick to view when skys are clear along with moon phases. Rise and set times.
Let down by a bug that prevents you editing negative longitude meaning that you have to use the place search which isn’t great.
