If you were to travel to Mars, you would have to be sure and pack extra thermal underwear! Compared to Earth, Mars is cold. The average temperature is negative 80 degrees Fahrenheit! (-62°C) On a martian mid-summer's day, however, the temperatures can reach almost 70°F, but summers are short, and the nights are cold, like desert nights.
Mars has storms, too, but not like the thunder and rain storms that we have on Earth. The Martian atmosphere has so little water (.03%) that the water-vapor clouds are very few, and very frozen. Instead, Mars experiences dust storms, and systems of dust clouds behave almost like storm systems on Earth. The fine dust of the Martian soil gets caught up and suspended in the strong winds which move them across the planet. There is no precipitation, but it takes a long time for the dust to settle.
While you're enjoying your stay on the planet of Mars, it is also important that you pack extra UV-blocking sunscreen. Mars has a very thin atmosphere compared with Earth's, with little ozone protection, so the planet's surface is constantly bombarded by the sun's ultraviolet rays-- the same rays that give you and I skin cancer.
