Google Weather API Widget (PHP) (No longer Working)




Note: Google has killed the free hidden weather API so this method no longer works

The Google Weather API is a hidden service for developers to get weather data for any location with ease.
Indeed, you just simply pass a city name or postal code, such as this Mountain View

Query by City
http://www.google.com/ig/api?weather=Mountain+View   

Query by Coordinates
http://www.google.com/ig/api?weather=,,,30670000,104019996 

To get an XML response like this:


This is the php code to get a widget like shown above. Line 20 defines the location for the widget.
Either you can use postal code, city or coordinates multiplied by 1000000 (Check Line No 21,22,23,25)

  1. Hi,
    The weather google api cannot be used. They treat thee request to get the xml file as an automated query, and just outputs this message:
    We’re sorry… … but your computer or network may be sending automated queries. To protect our users, we can’t process your request right now.
