    Hi Kanishk, great list. Can I recommend a really cool weather API which has just been launched – WeatherTrigger API.

    It lets you query past, current, and forecast weather data for world-wide locations, returning a ‘yes’ or ‘no’ response, which can be used to trigger an action. You can make the weather trigger any action you want. It’s free to integrate and start using, here’s the link: https://developer.weatherunlocked.com/ Let me know what you think. Thanks!

      WeatherUnlocked’s some datas are wrong. Sunrise, sunset, current temprature eg. Also it returns wrong coordinates to json than you give from url. Support is absolutely amateur. So you don’t use weatherunlocked api.

  3. bed777 says:

    Awesome!
    Take a look also at Metwit weather api: http://metwit.com/weather-api/

    We are crowdsourced weather API, something little different and innovative

    ;)

    You can also try to use Planet OS Datahub API http://data.planetos.com (contains over 2,000 climate and weather variables)
    If you want to check the API endpoints immediately feel free to look at the docs http://docs.planetos.com/#dataset-endpoints

    Disclaimer: I work at Planet OS and very excited about it :-)

    I have tried some of these services and here is my short review:

    – Open Weather Map – Fast and generous but not very accurate for some regions.
    – AccuWeather – Very accurate but I could not use my API key and the support team didn’t respond to my email!
    – Forecast.io – Very fast, good API documentations but just like Open Weather Map the data is not very accurate for particular regions outside of USA.

    I finally decided to use Wunderground weather service for my website. The free plan is limited but it was good enough for my needs. Here is the website: https://siahgumeshargh.com/weather – it provides weather forecast for cities of Iran.

  7. Colin says:

    I would recommend giving https://www.weatherbit.io a try. They have the exact same volume tiers as OpenWeatherMap, but they also give access to historical data. They also have a pretty generous free tier.

  8. Mark says:

    AccuWeather now offers a new API Developer Portal for easier access of the API: https://developer.accuweather.com/

  9. Stephane Cottin says:

    @Colin : the free plan openweathermap give more than the Megan plan of weatherbit .. ( 60 Calls per minute => 86400 / days )

    Dear folks,

    This might blow your mind: At Meteomatics you can have not only access to different weather forecasts based, for instance, on the global European model but also radar, satellite, ocean, terrain, tides data… And a downscaling of these data (times series, gridded, etc.) in up to 90m resolution:

    https://www.meteomatics.com/weather-api/en

    On top they support different programming languages like Python, Matlab, R, C++, Java…

    An extensive online documentation can be found here:

    https://api.meteomatics.com

    Best regards
    Martin
