Climate
Climates are the average weather conditions in different areas in the world of Songs of Syx. These conditions include temperature, humidity, atmospheric pressure, wind, and precipitation. However, temperate and precipitation are the most common factors seen in the game. When starting a new game, the player will be tasked with choosing a capital for their settlement, which involves monitoring the climate of where the player chooses.
Different races of citizens have preferences for specific climates. The frequency of immigrants from certain races are dictated by the climate of your settlement. A warmer climate will bring in more Cretonians, while colder climates will bring in Dondorians. Cantors don't seem to have a specific weather preference.
Temperature
Temperature plays a large part in the game, and if the player is not careful, it will claim the lives of citizens. To avoid extreme temperatures, a player can choose a "temperate" climate, although days of extreme temperatures can still occur, though it will not be as often as if you chose a "cold" or "warm" climate before starting the game.
Precipitation is also obviously affected by temperature, with either rain or snow randomly occurring. Building a hearth can help citizens get through cold days, as well as provide happiness. Clothing can provide protection from all types of weather. Skinny dipping can help citizens get through hot days.
