Seasons

Westeros's climate shifts from arid and dry desert climate in the furthest south to cold and harsh winters in the north and icy wasteland in the Lands of Always Winter in the farthest north.

Westeros and Essos both experience extremely long seasons of varying length, usually lasting at least a couple of years each. The maesters try to predict the length of the seasons, monitoring the temperature and days length, to advise on when to plant and when to harvest and how much food to store. However, given the random nature of the seasons, this is not something that can be relied on.

The Current Season is Summer as of 215 AC.
