During the Martian summer, the hemisphere facing the Sun receives more direct sunlight, leading to higher temperatures. This occurs in the southern hemisphere during the Martian months of October to March and in the northern hemisphere during the months of April to September.
Conversely, during the Martian winter, the hemisphere tilted away from the Sun receives less direct sunlight, resulting in colder temperatures. The opposite hemisphere experiences winter during the corresponding months.
The axial tilt of Mars is less pronounced compared to Earth, resulting in smaller seasonal temperature variations. Additionally, the Martian atmosphere is much thinner than Earth's, which contributes to more extreme temperature differences between day and night.
