The North and the South Poles constantly experience winter, with only minor changes in the weather conditions in the two seasons they have. The two seasons are summer and winter. The summer though is not real summer, as it has all the characteristics of a winter. The seasons on the poles are defined by the light they receive from the sun. In one half of the year, the poles are constantly experiencing day, thus the summer, while in the other half of the year, the poles are constantly experiencing dark, thus the winter.
