Grats anyway , that boss on Tyrannical is no joke <| sep |> time to get the pitchforks <| sep |> Supposedly , both Essos and Westeros are affected by winter . If I remember right , in ADWD Dany notices that the grass in the Dothraki sea has started to die off , but it ' s unclear if that part of the world gets a ton of snow . There are still daynight cycles , though depending on latitude and how far north a location is , the sun might not even rise in winter . If this is true , then you can presume that during winter the sun will set earlier in Winterfell than King ' s Landing if it rises in Winterfell at all . Looking towards the GOT world ' s equivalent of the tropics , there might be incredibly long wet seasondry season cycles , although that ' s never really been explored . One thing that ' s slightly unclear is if the whole planet is affected at the same time . If this winter operates like a real winter , then the southern hemisphere should be looking pretty inviting right now . But with the cause of the seasons apparently being magical , explanations based on realworld phenomena don ' t really hold up .
