In update 6, there was a new added option when you started a new game called "Weather". This option added temperature, you had to pay attention to rain, snow, heatwaves, and more temperature-related events.
It consists of 5 weather:
- Clear (no special effects)
- Overcast (no special effects)
- Rain (decreases temperature and prisoners will increase clothing need faster outside)
- Torrential rain (rare event, same as rain but with heavier effects)
- Snow and frost (sightly decreaces temperature)
- Heatwave (rare event, sightly increases temperature)
