Some other popular weather API's (I just found these descriptions online, I don't vouch for any):
AccuWeather Enterprise API
AccuWeather is one of the leading digital weather information providers. According to its website, AccuWeather provides weather forecasts for nearly 3 million locations worldwide, and over a billion people worldwide rely on AccuWeather every day. Its data is available in more than 100 languages and dialects.
Yahoo Weather API
Weather API provided by Yahoo. This will fetch up-to-date weather information for your location including 5-day forecast, wind, atmosphere, astronomy conditions
World Weather Online
Accurate and reliable world weather forecasts, forecasts up to 14 days as well as radar, satellites and historic data. They provide some additional tool like location search API and time zone API.
Realtime, on-the-fly adjustments, and flagging of data based on live backtesting/verification of model forecasts.
Australian Bureau of Meteorology API
The Australian Bureau of Meteorology is the government agency responsible for providing Australians with assistance in dealing with drought, floods, fires, storms and other harsh weather conditions. The agency also provides a variety of weather, climate and water data, including real-time observations, computer model forecasts and agricultural bulletins.
It can export a given station's latest weather data, pictures, and time-lapse videos. This API is provided by BloomSky, a hyperlocal network of weather cameras that provides real time visual weather information from around the world.
Founded in 1996, AerisWeather's mission is to "be the most dependable weather source in the country." The company provides detailed and comprehensive weather information, including local weather forecasts, extended forecasts and weather maps.
i did my with Accu Weather, its easy and similar route
I was just checking this course to study in a later date and found out that DarkSky API is gone, like said above.
I checked other options and AccuWeather seems to be paid.
I found some 2 popular options to the already cited above ones.
