Keep in mind, This is a weather prediction system and it may not be entirely accurate at times.
(Just like real life weather forecasts).
The system does what it can with the data it's provided and makes calculations based on those.

1. This mod runs on the server side, but is required by clients due to the newly created module.
2. Set Clouds on "Ultra" in video settings for best effects
3. You do need your own API key. You can get one for free at


Where is the module?
The module is located in the games editor
("Systems" >> "[HZ] Real-World Weather" >> "Real World Weather")

Can I search for my own Weather Stats anywhere in the world?:
Yes!, This System allows for dynamic search query's all over the world.
With your own key simply enter the Country and City you want weather from.
Everything is available to you in a easy to use Module

If you are having issues getting data from the places you want, follow the steps below.

To test if the API is returning the data open your web browser and do the following.,Toronto

Replace "YOURKEY" with the key you recieved from WeatherStack
Replace "COUNTRY" with the name of the country, example. Greece
Replace "CITY" with the fullname of the city you are requesting.

Can I search using (Lat, Long) co-ords?
Yes, If you have your own key.
Replace Country with the latitude.
Replace City with the longitude.

What is a API key and do I need one?
Yes, This mod does require you to own a API Key!.
In short, API keys are unique id's which allow access to the Specific data services like Google, Yahoo etc and are needed to prevent abuse and overload of the systems.
Free API keys are usually limited to (x) amount of calls per hour or per day.

@ALL - Since I could not get the author to reply to my message below, I have made this mod work on any map without having the actual module placed on the map. In other words, you just run a script and it will set the weather for you. No need to edit the map or be stuck with one 'setting' of weather.

If you would like the scripts to do this, send me a friend's request. Do note, you will still need to use this mod - just have it loaded, nothing more, as my scripts call his.

@Hortzy - Thank you for your time and effort with this mod. I did have a question for you. How can I have 'on the fly' weather for any map. I run a script with correct settings such as location, key, etc., and have it set the weather. In other words, without using the module. The use of the module limits usage to maps that have this placed.

For example, in the East Wind Campaign:


[] spawn RWW_SetWeather;

Then I run [] execVM "CurrentWeather.Sqf" and the weather is set without the need for the module.

The above is just an example.

Looking forward to your answer and thanks!
