    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.

    We are crowdsourced weather API, something little different and innovative

    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.

    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.

    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

    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.

    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.

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