Our ever-expanding network of 250,000+ personal weather stations is the largest of its kind and provides us with a unique ability to provide the most local forecasts based on actual weather data points. I don’t know if such services are available in other countries.All of our forecasts are generated from our proprietary forecasting system that leverages our vast amount of neighborhood weather data that we get from our community - we refer to the system as BestForecast™. 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. For historical data, one can access the US Government’s historical weather data source, which includes foreign countries. 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.
