Eli5 – Why does air “looks” colder in winter ?

225 views

So, temperatures are dropping below the 0°C where I live, and I was wondering why does it seems like everything has a “cold color” filter applied to it ?
It’s almost like I have a veil in my eyes that makes everything I look at outside whiter or greyer, even when this is bright sunny, and I really don’t think it is something about a psychological bias because I do prefer colder seasons over hotter ones.

Thanks in advance !

In the winter the temperature of the air is lower, which causes it to hold less moisture. When there is less moisture in the air, the air appears to be clearer and more **transparent**, which can give the impression that objects are further away and the colors of objects appear less vibrant. Additionally, the angle of the sun during the winter months is lower in the sky, which can also contribute to the perception of coldness by casting longer shadows and reducing the amount of direct sunlight that reaches the ground.
