The surface temperature on Mars varies between a low of negative 225 degrees Fahrenheit at the poles and a high of 70 degrees Fahrenheit at the noontime equator during summer. Between the equator and the poles, the temperature averages between negative 76 and negative 58 degrees Fahrenheit.
During the summer, the high temperature in the mid-latitudes is about 32 degrees Fahrenheit. The temperature is low enough for frost to form during the night, followed by relatively high humidity in the morning as the frost evaporates. Because the planet tilts along its axis, Mars experiences seasons in the same way that Earth does. The polar ice caps can disappear entirely during summer.
