Temperatures on the moon range from extremely hot, up to 123C (253F) when the sunlight hits the moon’s surface, to a freezing cold minus 153C (-243F) on the dark side. As there is no significant atmosphere on the Moon it cannot trap heat or insulate the surface

LRO Diviner Lunar Radiometer Experiment surface temperature map of the south polar region of the Moon. The data were acquired during September and October 2009, when south polar temperatures were close to their annual maximum values. The map shows the locations of several intensely cold impact craters that are potential cold traps for water ice as well as a range of other icy compounds commonly observed in comets.
