What's the weather like on Mars?

The atmosphere of Mars contains 95% carbon dioxide, but its gravity is relatively small. Most of its original gas has been blown away by the solar wind. The average pressure on the surface of Mars is 0.008 standard atmospheric pressure (8 mbar). Low air pressure, coupled with extreme dryness, prevented the formation and accumulation of water. This means that there are almost no clouds on Mars, and the thin atmosphere makes Mars very sensitive to the heat of the sun: for example, the temperature at the equator varies from-193 F to+72 F (-125 C to+22 C) all year round. Ice covers the poles of Mars. Their melting and freezing are affected by the distance between Mars and the sun, and also by the wind with a speed of 125 miles (200 kilometers) per hour. It produces powerful dust clouds, blocks sunlight and slows down the melting of ice. These dust storms often attack the whole star.
