Snow refers to two intrinsically linked mechanics - weather of that name and the terrain covering that it creates. Snow on the ground is created on unroofed areas during snowy weather, i.e. "rain" when the temperature is freezing. It will cover solid terrain but will not cover water of any type, including marsh.
It can be removed by fire, steam geysers, lightning, colonists when designated with the Snow Clear Zone, and by temperatures above 0 °C (32 °F).
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% |
Depth

Various depths of snow exist, with deeper levels hindering movement more. Depth is an internal value, measured from 0% to 100%, hidden from the player.
| Level | Depth range | Move speed |
|---|---|---|
| Dusting | 3% ≤ 𝑥 < 25% | 100% |
| Thin | 25% ≤ 𝑥 < 50% | 76% |
| Medium | 50% ≤ 𝑥 < 75% | 62% |
| Thick | 75%+ | 52% |
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.
