"...the Northern Hemisphere winters are colder and the summers are hotter due the preponderance of land masses in the Northern Hemisphere; land areas that collect heat during the day quickly radiate that heat into space under the cover of darkness at night. Conversely, the oceans are warmed by sunlight during the day, but release that heat more slowly at night. This is why land areas show such a large range in temperatures. . . in parts of Siberia, the summer temperatures can top 100 F and the winter can fall to -60 F. Oceans do not see anywhere near that type of temperature change and serve as a moderator. There is far more ocean area in the Southern Hemisphere than the Northern Hemisphere, which is why south of the equator, winters tend to be milder and summers cooler compared to the Northern Hemisphere -- in spite of the fact that for folks in South Africa and Australia, we are farthest from the Sun in July (their winter) and closer to the Sun in January (their summer)." -Joe Rao
