OS Weather transforms Minecraft's Overworld with a dynamic, localized atmospheric simulation.
Instead of a single global weather state, different regions experience their own conditions influenced by biomes, temperature, humidity, pressure and wind.
From clear skies and rainfall to snowstorms and extreme weather, the atmosphere evolves naturally as you explore.
One world. Different climates. A living atmosphere.
Customize client visuals and server weather behavior through configuration files or the optional in-game settings interface.
Commands: /osweather status, /osweather info, /osweather set, /osweather clear, /osweather reload
Vanilla /weather commands are also integrated.
