It is visibly winter when the plot of the first season happens, all characters are wearing layers of clothes and coats in the Israeli winter which is usually in the Rishon LeZion area roughly 5-15 degrees in the winter. However, when the characters are in Uman which is in the freezing in the winter, and even Tal and Izzy comment it is 20 degrees lower then home, they are dressed exactly the same, which in the real winter make them extremely uncomfortable, and there is no snow or ice visible in the streets.
