Rats. Hit the send button by mistake. [email protected]#$%&* !!

Mars' axial tilt gives it seasons much like Earth's. See-

For more stuff than you'd ever want to know about the Earth-Mars
similarity, see-

Half of the time.

As on earth, if it's summer in one hemisphere it's winter in the
other, and this applies in every other quarter of the year. So you
need to specify which side of the Martian equator you're thinking of.

Wouldn't that techically be all the time then?

Hi Odysseus I would think like the Earth Mars south pole would be the
coldest. Could at the Mars poles be any CO2 snow flakes? Maybe a sand
storm kicking up some of that frost. Seems the extreme temperature drop
from day to night on Mars might be a greater extreme than the hottest
summer day at the Earth's equator as to its coldest day in winter at the
south pole. Mars must have a permanent frost just 6 inches under its
surface at its equator That could be the reason large rocks sit so high
up on its sandy surface. Bert.

Well they certainly don't seem to have a spring time, so we can discount the
equinoxes.

Who knows.. maybe the martians have a weather control device that is under
the "face"! LOL

Why not? As it has almost the same axial tilt as Earth, Mars has seasons
in the same way. It has winter in one hemisphere when the polar cap
warms up and evaporates so the atmospheric pressure goes up, and
meanwhile the other hemisphere has summer. There's the added
complication of an eccentric orbit, much more than on Earth.
