For fans disappointed that the next series of Game of Thrones won't be on our screens until 2019, here's some food for thought: an attack on Westeros would be most likely to come from the south in winter and north in summer, according to a climate model of the world of Game of Thrones.

Furthermore, the model also sheds light on many mysteries surrounding the climate of the lands of Westeros and Essos - including the likely hibernation zones of White Walkers and the similarities between The Wall and Lapland.
