In general, Mars has highly variable weather and is often cloudy. The planet swings from being warm and dusty to cloudy and cold. Mars long ago was likely a warmer, wetter planet with a thicker atmosphere, able to sustain oceans or seas.

Does Mars have weather or storms?

The weather on Mars is quite different from that on Earth, but its atmosphere and climate are also more similar to Earth's than any other planet. Martian weather is relatively colder than Earth's (as cold as -195 degrees Fahrenheit) and often features vast dust storms.

Does it rain on Mars?

Mars may have once had planet-wide rain and snow storms that filled lakes and rivers with liquid water, according to new research. Planetary scientists can see that riverbeds and ancient lakes litter the Martian surface, but have so far been unable to figure-out what Mars' climate must have been like to produce them.
