After install this extension open Nautilus and navigate to ~/.local/share/gnome-shell/extensions/[email protected] (.local is a hidden folder so press CTRL + H to see it), open the “extension.js” file and replace the following: “const YAHOO_ID = ‘AUXX0010’;” (it’s on line 48 for me) with the YAHOO weather ID for your city.
To get your city’s Yahoo ID, go to http://weather.yahoo.com/, and enter your city/zip code and when you find it, look for the orange “RSS” icon on the right. Hovering this icon, you’ll see your code – copy it and replace the “AUXX0010” code in the extension.js file.

After you finish editing the extension.js file, save it and reload Gnome Shell or log out and log back in.
