What the weather does

How each kind of weather changes how far the infected and wildlife see, how far sound carries, and how far your scent travels, against a clear day.

12 rows

Rain and storms hide you: sound and scent carry far less. The infected, half blind in the rain, listen harder all the same.

The ground remembers the weather. Wet and snowy ground changes grip, tracks and travel.


Ground soaks through	After 8 minutes of steady rain.
Ground dries	In 60 minutes at 20 °C when it is calm and clear. Warmth, wind and sun speed it up.
Snow covers the ground	After 15 minutes of heavy snow.
Snow melts	Above 1 °C. Full cover melts in 40 minutes at 10 °C above that, and heavy rain washes it away in 30 minutes.
Mountain trails	Close to vehicles once snow cover reaches 60%.

Your core temperature drifts with the air, the wind, wet clothes and what you wear. These are the thresholds.


Heat death	41.5 °C	Fatal.
Heatstroke	39.6 °C	Collapse is close. Get into shade and water.
Overheating	38.3 °C	You sweat, thirst climbs and stamina drops.
Healthy	37 °C	Held when the air feels between 12 °C and 29 °C for what you are wearing.
Cold	35.6 °C	You shiver, which burns food faster.
Hypothermia	34 °C	Shaking hands, slow legs, hunger climbing fast.
Severe hypothermia	32 °C	You are close to collapse.
Death from cold	30 °C	Fatal.

Bare hands or feet start to freeze after 4 minutes in a wind chill of -10 °C or lower.

Wet clothes cost 0.12 °C of warmth for every point of wetness. A fire dries you 7 times as fast as the open air.
