The indicated measured average values ​​of heat on the surface of Mars are 63 ° C below zero. The lowest temperatures around 120 ° C below zero and the highest temperatures around 27 ° C above zero were recorded during the Viking mission. However, the question is whether these values ​​are really relevant to us as we would understand them on Earth. Even on Earth, the difference is whether you measure 30 ° C in Prague (Central Europe) or in Cairo (almost the equator near the sea). Other factors such as altitude, humidity, pressure, chemical composition and density of the atmosphere, distance from the Sun and the ability of the Earth's (Martian) surface to absorb heat and radiate back must also be taken into account…

The atmosphere of the Red Planet is said to be much thinner than on Earth. So the changes in the weather here should not be as dramatic as on Earth.

Canadian physicist Randall Oscezevski said that subjective perceptions of temperature on Mars would be somewhat different in terms of local atmospheric properties than indicated by thermometer numbers. The pressure on Mars' surface could be compared to the pressure on our planet at the height of 32 km above the Earth's surface.

Oscezevski further states that thermometers on Mars tend to perceive the planet much colder than humans would perceive it. He likened the Martian equator to the temperature conditions we can experience in the south of England. We would then perceive sunlight similarly to Earth.
