It's F.O.S.S.

Ubuntu’s default Weather Indicator, which is certainly among the most popular applet indicators, has been removed from the official repository as it was found to be broken in Ubuntu 13.04. Weather Indicator crashes when trying to add a new location and the weather forecast doesn’t work at all. That left users to opt for My Weather Indicator, another weather app with more option than the good old Weathe Indicator.

Good news is, thanks to Joshua Weather Indicator has been fixed now. Though the fix is not available in Ubuntu Software Center yet, you can use it by adding the PPA provided by Joshua.

Install Weather Indicator in Ubuntu 13.04:

Open terminal and use the following commands:

sudo add-apt-repository ppa:jtasker/weather-indicator
sudo apt-get update
sudo apt-get install indicator-weather

Once installed, you can open it by looking for it in Unity Dash. You need to configure it just once and it will be automatically started at every boot. The most important configuration you need is to add your geographic location. Also, don’t forget to check “Show temperature near indicator” box in the preferences to display the current temperature in top panel.

I hope that you install Weather Indicator easily with this PPA. I took the liberty of not explaining the steps to configure it as it is very simple. But feel free to ask for it, if you face any troubles. Do you still find some bugs in it? Do let me know. Enjoy
