About Us

 Free Weather Data puts quality weather data in your hands, 

very well detailed data since 1961.

 We are immensely proud of our meteorological data that were created to improve

people's free access to data significant weather from around the world.

As the 1st meteorological service free internet, we are proud

to share more data with more people for free.
