  1. 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.

  2. Hi,
    we need to access current weather and forecast weather through API or FTP.
    if there is any paid subscription for this information through API and FTP
    can you please send all details in mail and send me on my mail id.
    Our requirement is to know the current weather and forecast weather information for US.
    can you please help me out on this,we are interested to buy.

  3. 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.

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

  5. 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:


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

    An extensive online documentation can be found here:


    Best regards

  6. Wow Martin !

    Your service is ***starting*** at 250 € per month

    Why that means ***starting*** at only 3000€ per year.

    Seems ideal for any home use application.

  7. And in other news, both Yahoo Weather and Weather Underground (the two services apparently used the same data source) have from December 31st, 2018 discontinued their free weather data service.

  8. Why would I use a free, open source API rather than a super nice service starting at just 250 € per month? Good try, Martin!

  9. Hi Kanishk,

    Awesome article! I wanted to encourage you to check out AerisWeather: https://www.aerisweather.com/

    AerisWeather’s API provides a broad range of hyper-local environmental data for global businesses. Our API meets the demands of developers, product managers, and data scientists around the globe with access to historical datasets, granular forecasts, and unique data endpoints like severe weather alerts, tropical storms, air quality, lightning strikes, and wildfires. See them all in the Weather API Documentation and try the API Wizard to craft your API requests immediately.

    I think it would be a great addition to your article, and I’d be happy to discuss how to make that happen.

    Thank you!

  10. The company I work for, Visual Crossing, offers a Weather API that includes 15-day forecast, hourly and sub-hourly historical data. We offer 1000 free results per day and then pricing starts at $0.0001/result. There are also monthly plans for higher volume users.
