Having a problem with the weather or time display in YoWindow?
You will find the answer in the Troubleshooting section.


Please, add more weather providers!

We want to add as many weather sources to YoWindow as we can.
But, there is a problem.

Most weather services sell weather data to appliation developers.
Usually, the weather data are not free.

As an example, Weather Undeground charges $200 per month for 100,000 weather requests per day.

At this moment, YoWindow users request current weather more than 5,000,000 times per day. We just cannot afford to pay that much.

We are open to partnership with weather providers.
We will be happy to integrate your weather to YoWindow!

Where YoWindow takes the CURRENT weather from?

YoWindow takes the current weather from METAR stations network. There are around 4380 active METAR stations scattered around the world. Most of them are located in airports.

YoWindow picks the closest METAR station to the location you choose. Then the current weather is loaded from this station.

You can find METAR stations near your place on this site.

In mobile editions of YoWindow you can also choose the following current weather providers.

If you know a FREE weather service, let us know. Contact us

Where YoWindow takes the weather FORECAST from?
Weather forecast data are provided by one of the following organizations, depending on selected location and program settings

  • yr.no, the forecast is delivered by the Norwegian Meteorological Institute and the NRK
  • NWS - National Weather Service
  • Open Weather Map

We want to express our unlimited gratitude to yr.no team for giving us the opportunity to use the top quality weather forecasts.


Can I change the current weather station (METAR station) for my place?


Go to main-menu/Location/Location Properties
Enter ICAO code of the station in METAR/Code
Click OK, enjoy!

But how do I find the closest METAR stations to my place?


How does YoWindow choose the season?

YoWindow does not know when the seasons change at your place.
But, it is trying hard to guess the correct picture.
There are 5 seasonal pictures in YoWindow - winter, spring, summer, naked and autumn.

YoWindow picks the picture according to the season-map for the place.
However, there are some rules that override the season-map choice.

  • When the temperature less or equal to -5°C (23°F), winter season displayed.
  • When the temperature is more or equal to +5°C (41°F), YoWindow thinks that all the snow has melted and displays naked season instead of winter.


What is Season-Map?
Season-Map is a string describing the dates when the seasons change for a place on Earth.
This is the season-map for New York:
The format is simple - a sequence of [date:season] pairs, each pair shows when the season starts in average.

YoWindow picture is changing according to season-map, however there are some exceptions. How does YoWindow choose the season?

We have composed a collection of season-maps for many points on Earth.
A season-map for selected location is taken from the closest point.

To view the season map inside YoWindow go to main-menu/Location/Location Properties...

The season-maps are composed from historical weather reports and the feedback from YoWindow friends around the world.
If you think the season-map for your place is completely wrong, you can correct it by submitting your season-map to our YoWindow season-map forum.

Please submit the season-map ONLY if the difference between your and YoWindow season-maps is significant.

How do I find the closest METAR stations to my place?

Probably the best way to browse METAR stations is Google Earth.

1. Open Google Earth METAR layer right inside your browser.
NOTE: You will be requested to install Google Earth plugin. Confirm the request.

Just find your location and you will see the METAR stations scattered around.
Click the one you like to find the ICAO code.

2. Open METAR layer inside your Google Earth:

3. If Google Earth does not work for you, try this simple METAR map solution

When you find a weather station of your choice, click it to find the 4 letter ICAO code, like "KBKV"

You need to enter ICAO code inside YoWindow to start updating the current weather from the station.

Why YoWindow Live Wallpaper disappears after I reboot my Android?

Looks like you have installed YoWindow Weather onto external (SD) card.
You need to move YoWindow to the main memory of the device.
Android Live Wallpapers do not work properly if they are installed on external card.

How can I remove the message displayed over the YoWindow Wallpaper?

There are 2 options.
1. Tap on the message - the "close" button will appear at the top right corner of the message. Tap the button and the message will be gone forever.

2. Add YoWindow widget to the desktop. The message will go away forever. You can remove the widget unless you want to keep it.


'Plugin Blocked' message instead of beautiful YoWindow landscape. How do I fix this?
Usually upgrading Flash Player helps.
If it doesn't help, remove Flash Player and then install it again.


Where may I find YoWindow Landscapes?

Short answer: in our Landscape Collection

However, it depends on a kind of landscape you are looking for.
There are three types of YoWindow landscapes.

1. Animated landscape - YoLandscape.

This is the most impressive kind of a landscape.
The landscape changes along with the weather, season and sunlight.
There are many living objects like smoke, grass, trees, animals and so on.

There are 4 YoLandscapes available - Village, Seaside, Airport and Oriental.
The work on new YoLandscapes is in progress.

2. YoWindow landscape made from a regular picture.

A regular picture looks amazing when the sky is replaced with YoWindow living sky.
This is a picture of Rome Colosseum we have found on Flickr.

Original picture

Now have a look at the same picture inside YoWindow.
Scroll the time to experience different light and weather conditions.

You know what?
You can create a landscape like this yourself.
From your own picture, taken with your camera.
Follow our tutorial explaining how to turn a regular picture into YoWindow landscape.

There are many live-sky landscapes created for YoWindow by our friendly community.
The landscapes are made from real photos taken around the world.
Browse through our Landscape Collection.
We wish you to find the landscape of your dreams :)

3. A picture.

You can open any picture or photo inside YoWindow.
YoWindow will take care of the weather and sunlight.
The picture will be covered by rain, snow or mist depending on the weather.
It will fade-out in the night and fade-in on the sunrise.

Make sure you have picked the right picture.
YoWindow expects the picture to be taken on a sunny day.
If you pick a night scene, it will look dark in the day and very dark in the night.
Try to pick a picture taken when the Sun is shining.

Picture width or height must not exceed 2880 pixels, otherwise YoWindow will not be able to display it.

Try it yourself!
  • Run YoWindow desktop edition
  • Go to main-menu/Landscape/Add...
  • Click "Browse" button to locate a picture on your system.
  • Select a picture
  • Click OK to select the picture as the landscape
How to install YoWindow Landscape?
Installing a landscape is easy.
Let me explain with an example.

This is one of many posts in our Landscape Collection featuring Colosseum.
Rome, Colosseum post

1. Find a link to colosseum.zip file at the bottom of the post.

Follow our Blogger Weather widget tutorial.


Give me the list of the widget parameters!

You have it!

How to load my landscape inside the widget?

Follow our tutorial.


blogspot.com Why my weather widget does not reflect settings (language or temperature units, etc)?

Most likely a part of HTML code is garbled after the widget gets added to the blogspot.com.
By some reason "amp;" text is getting added twice in flashvars parameter value.
This is how the problem usually looks, the redundant characters are highlighted in red:

<param name="flashvars" value="location_id=gn:3430863&amp;amp;time_format=24;amp;

Remove amp; manually to resolve the problem.

YoWindow does not work

Please Download the latest YoWindow and install it.

YoWindow builds prior to 494 will not work with Flash Player and later.
We are sorry to disturb you with an extra download

"Weather expired". Why? How to get rid of this message?

YoWindow takes the weather from the Internet service, which in turn takes the weather from weather stations around the world.

Usually, the weather is delivered to YoWindow in 10 - 40 minutes after the moment it was observed at the station. In a case when the delay exceeds 2 hours, the "Weather expired" warning is displayed. This is a signal that the weather in YoWindow may have nothing to do with the actual weather outside. If there's something wrong with the weather, YoWindow lets you know.

There are several causes that may lead to "Weather expired" warning.

1. Weather station (METAR station) is not reliable.

YoWindow takes the current weather from airport (METAR) weather stations. The most closest weather station to the location is picked. However, the weather station may not be a reliable one. For example, it may not provide the weather in the night or on the weekends. Or it may provide the weather in a very long intervals like 4 hours. We are constantly working on exclusion of the unreliable weather stations, but this still maybe the case.

If the weather station is not reliable, please report it, we will exclude it from YoWindow. Contact us

Alternatively, you may change the METAR weather station manually by entering ICAO airport code in Location Properties dialog.

You may check if the weather station is reliable.
  • Go to main-menu/Location/Location Properties
    There you will notice "METAR" section along with "Code:" line. There is a "www" link.
  • Click "www" link and the page of the weather station will open.
  • Find "Current weather observation" section.
    In the table, in the first line the age of the weather data displayed.
    Like "The report was made 29 minutes ago, at 04:50 UTC".
    If the age is greater than 2 hours, the weather station is not reliable.

2. Networking problems.

As you may know Internet is not 100% reliable. Sometimes a site does not open because of network problems for a certain period of time.
YoWindow loads the weather over the Internet.
And if the Internet does not work, YoWindow cannot load the weather.
Wait a couple of hours, if the problem still exists, most likely this is not a networking problem.

3. YoWindow version on your system is too old.

Make sure you have the latest YoWindow version installed.
An old version may not load weather automatically on certain systems.
Uninstall YoWindow and then download the latest version from this page:
To find the version and the build number of YoWindow, go main-menu/Help/About

4. Make sure the time on your computer is right

YoWindow goes crazy if the computer time is different from the actual time by 15 minutes or more.

Do not trust the time you see on the Windows clock. It may show you the right time, but if the time-zone is set wrong, the time is wrong!

Follow these steps to make sure the computer time is set right.

5. Something else

If you still keep getting "Weather Expired" warning, this must be a very special case on your system.
Please Contact us

When I'm trying to choose my location I see "Network error..."

That means YoWindow cannot connect to our server or the Internet.

This may be a temporary problem due to network issues on our side.
However, if you see this error all the time, most likely YoWindow is blocked by a Firewall software (usually Windows Firewall).

Follow these steps to troubleshoot the problem.

1. Exit YoWindow. DO IT RIGHT: through main-menu/Program/Exit.
Otherwise YoWindow may just close the window, but not to exit.

2. Turn your Firewall software temporary OFF.

3. Run YoWindow again.

Check if you can choose a location this time.

If YoWindow works properly - you can select the location - you need to grant an Internet access to YoWindow in your firewall software.
Otherwise YoWindow will not be able to update the weather.


No problem!
1. Go to Options/Advanced
2. Check "Show small YoWindow logo" mark.
3. Click OK
Why the landscape is covered with snow? Why there are no snow on the ground?
There are no snow cover level information in the current weather (METAR) reports YoWindow receives.
YoWindow it trying to guess if there is snow on the ground.
A simple snow detection algorithm is used for this purpose.
Unfortunately the algorithm does not work under some conditions.

We hope to improve the snow coverage detection algorithm by the next winter.
For the moment it is the way it is.

I don't see temperature in the system tray (beside the clock).

Most likely YoWindow icon is hidden from the notification area (system tray).
This is a common case on Windows 7.
You need to allow YoWindow temperature icon to be displayed.
This article explains how to fix this the problem on Windows 7.
This article explains how to fix this the problem on Vista.

On older Windows versions follow the same approach.

To change the color of the temperature text open YoWindow and go to Options/Advanced/System tray

Norton Internet Security displays a warning for YoWindow and then deletes it

I should say, if you have downloaded YoWindow from yowindow.com you can trust it. Norton Internet Security just gives you a warning that it does not know this file.

Because YoWindow is updated so frequently, it is hard for Symantec to speed up to us. In a case Norton does not know anything about new program - new build of YoWindow in this case - it prefers to warn a user with a scary message. Just in case.

Norton Internet Security is suspicious to a new build until 100 members of Norton Community to install it.

This article on Norton Community site explains how to workaround the problem.


The time is displayed wrong for my place.

YoWindow designed to automatically detect local time for any place in the world. And it does the job pretty good. However, a mistake is still possible since time-zone rules are changing over time by some countries.

If a daylight time change occurs while YoWindow is running, YoWindow is not able to detect it. YoWindow will keep displaying the wrong time until you restart it.
To restart YoWindow go to main-menu/Program/Exit. And then launch YoWindow again.

But in most cases, the cause of this problem is the wrong time set on computer.

Follow these steps to make sure the computer time is set right.

  • Open Windows time settings. There you will find the time zone set on your computer, like this "(GMT-08:00) Pacific Time (US & Canada)". Make sure this is the right time zone for the place where you are now.
  • There you may also find this option: "Automatically adjust clock for Daylight Saving Time". We recommend to set this option checked.
  • Now adjust computer time if it does not match to the actual time at your place.
  • Press OK to apply and exit time settings.

If the computer time is set right, but YoWindow still displays the wrong time for your place, please Contact us, we will help.


When I click on a button or the menu it does not respond. Why?

It seems that the default display scale factor is altered in your Windows settings.

YoWindow can only operate properly when the display scale factor is 100%.
When you change it to 125% or 200% YoWindow goes crazy.

We have tried hard to fix this problem, but still cannot find a solution.

You can check and modify display scale factor in the Control Panel display settings.
Control Panel\Appearance and Personalization\Display
And there "Change the size of all items" section.

As a workaround, in YoWindow, press F11 to enter full-screen mode.
In full-screen mode the bugs will go away.
You will be able to interact with the buttons and the menu.
