Look at
http://calspace.ucsd.edu/marsnow/lib.../seasons1.html
for an explanation of how Martian seasons work; it will be summer in the Souther Hemisphere, now, as the south Pole is pointed toward the Sun (and the Earth)... Mars is near Perihelion, too, so the summer in the Southern Hemisphere must be warmer than summer would be in the North.

Jupiter doesn't have very strong seasons, as far as I know, but Uranus definitely does, and Neptune does as well, I believe.
The important factor in most planet's seasons is the tilt of the axis, although Mars is also affected by the eccentricity of its orbit; (that is, how far it is from the Sun);

Earth in contrast has seasons almost entirely dictated by the tilt of the axis.
The sun is of course closer to the Earth in the Winter in the Northern Hemisphere.
