Real World Weather


- Integration of a real-time weather API into arma 3.
- Grabs Real forecast data from an official reliable Weather Provider.
- Uses terrains Real World Counter-part
- Predicts future forecasts based on actual weather statistics.
- Option to sync time with location.
- Adds extra Immersion and Feel
- 3den Editor Extension (highly customizable module).
- Real-time weather Debug console.
- 32 and 64 bit support
- Auto config option included

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. More maps supported by default will be added by request and demand.
3. A Scripted option will be available for server owners who do not want to create a dependency!
4. Set Clouds on "Ultra" in video settings for best effects
5. It's always recommended to get your own API key for better "real-time" results.
(Default system without a key is based on the last 60 mins).
6. DO NOT share your personal private API key.
7. DO NOT release a public scenario with your API key included.

To install Real World Weather you should use modfolders to keep it seperate from the official game content to prevent issues.
With Arma 3 you can use different ways to set up your modfolders to use custom content you have downloaded.
Please visit the Arma 3 Mod install instructions page for more information about using custom mods and addons in Arma 3.

Included files:

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

Where can I compare the real weather vs in-game?
Results between Altis and Stratis are nearly the same, as they both use Limnos weather station!
*Note: If you are not using your own key, Results in-game may be delayed by 60 minutes.

Supported terrains and link to current weather:
Altis (Limnos, Greece):
Stratis (Agios Efstratios, Greece):
Tanoa: (Lovoni, Fiji)
Chernarus (Mojzir, Czech Republic):
Imrali: (Imrali, Turkey)
Takistan: (Jelgah, Afghanistan)
Australia: (Sydney, Australia)
Sahrani: (Feteiras, Portugal)
Taunus: (Taunusstein, Germany)
CLAfghan: (Asadabad, Afghanistan)
Porquerolles: (Porquerolles, France)
Bornholm: (Ronne, Denmark)

Can I search the console without a key?
Not really.
But if the API key field is set blank, you can use it to refresh/retry with auto-config

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.

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.
Note: Lat and Long coords must land on a weather station for that area

What is a API key and do I need one?
No, This mod does NOT require you to own a API Key!.
Although for advanced settings and customization it is recommended! (They're free anyways!).
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 limited to (x) amount of calls per hour and per day.
For more info on API keys or how to get your own visit.

Why is the update cycle set to 60mins without a key, and How does the weather get updated?:
I use my own API Key to automatically update a personal website every hour with REAL weather data.
Which allows ALL users to access and enjoy this system on default terrains without a need for a Key or being worried about API Limits.
IF you are using your own Unique Key, The system will then proceed to query Wunderground's API and discontinue using my site.

Anything is really appreciated and it keeps me motivated!
