Snow is created on unroofed areas during snowy weather. It can be removed by colonists when designated with the Snow Clear Zone. Fire, steam geysers, lightning, and temperatures above 0 °C (32 °F) melt snow.
Colonists may build snowmen as a recreational activity when there is snow on the ground.
Weather
There are two types of snowy weather: gentle snow and hard snow. These can occur at temperatures of -0.5 °C (31.1 °F) and below.
| Weather | Accuracy modifier | Move speed modifier | Snow rate |
|---|---|---|---|
| Gentle snow | 80% | 100% | 120% |
| Hard snow | 80% | 80% | 80% |
In snowy weather, snow gathers on the ground as long as it is unroofed. Various depths of snow exist, with deeper levels hindering movement more.
| Level | Depth range (%)[1] | Move speed (%) |
|---|---|---|
| Dusting | 3 ≤ 𝑥 < 25 | 100 |
| Thin | 25 ≤ 𝑥 < 50 | 76 |
| Medium | 50 ≤ 𝑥 < 75 | 62 |
| Thick | 75+ | 52 |
- ↑ Depth is an internal value, measured from 0% to 100%, hidden from the player.
Melting
The melting rate of snow from ambient temperature is found using the following table:
| Temperature range | Melting rate (depth %/tick) |
|---|---|
| 0 °C (32 °F) and below | 0 |
| Between 0 °C (32 °F) to 10 °C (50 °F) | 0.058% of temperature² |
| 10 °C (50 °F) and above | 0.58% of temperature |
As a result, snow will not be melted by ambient temperatures of 0 °C (32 °F) or less, and the higher the temperature the faster the snow will melt.
