Nations treasure of climate and historical weather data and information. I don’t know if such services are available in other countries. Here we list a number of external data sources we have used in our projects. But, these are just for locations in the USA. The output can be programmatically parsed and applied. Something that may also be of interest, provides free weather forecasts and can be programmatically queried via its REST interface. Each person should decide if those predictions are worth the money, given the application at hand. Many of these sites use the results of three different physics models to predict weather. If those are required then there may be a need to access formal weather-prediction sites, of which there are many. (During the present government shutdown, this site is dormant.) For instance, I have downloaded historical weather data for a specific weather station in Ethiopia going back to 1957, and have used this data to drive an evapotranspiration model ( ) and to build a statistical rain-prediction model ( ).Īt issue is that this site does not produce weather predictions. Unfortunately, historical data are not easy to access.
For historical data, one can access the US Government’s historical weather data source, which includes foreign countries. Scraping 5-min weather data from Weather Underground Zach Perzan Scraping 5-min weather data from Weather Underground Weather Undergound stores data from over 250,000 personal weather stations across the world. But, if I have my own weather station, there is no need for me to pay to access another source for current data. For weather data providers, WeatherUnderground’s plans are good. has free data feeds for airport stations too (and some private weather stations).
