	Martian perihelion is during the southern hemisphere's summer. Since Mars has a fairly elliptical orbit, this means that the southern summer is short, and the southern winter is longer (than the northern hemisphere). The difference between the insolation between when Mars is closest to the sun, and when it is farthest away is 40%. (Earth is 6% because its orbit is more circular.)		Martian perihelion is during the southern hemisphere's summer. Since Mars has a fairly elliptical orbit, this means that the southern summer is short, and the southern winter is longer (than the northern hemisphere).

			The difference between the insolation between when Mars is closest to the sun, and when it is farthest away is 40%. (Earth is 6% because its orbit is more circular.)

			So the Southern Hemisphere has summer when Mars is closest to the Sun, which makes it hotter. However, the summer is short, and the winter (when it never sees the sun) is long. This dominates the temperature differential, northern summers are warm, and southern winters are brutally cold.
