The Moon landings were always set by NASA to occur when the sun was at 30 degrees above the horizon in the Lunar morning. This was for two reasons. First, the illumination at that sun angle makes it easier to pick out boulders and craters and other landing hazards so the LEM pilot could land safely. The other reason was that the temperature of the surface soil is the most earthlike at that time in the lunar "day", i.e. around 70 degrees F.

Temperature measures the energy per "degree of freedom" (i.e. way something can move) of whatever molecules happen to be around. So, it it becomes so cold that the molecules stop all together, then this is the "absolute zero" temperature. On the Celsius Temperature Scale (i.e. water freezes at 0, and boils at 100) this takes place at -273 degrees C.
We usually use the Kelvin temperature scale, where Zero Kelvin is this "absolute zero" temperature -- or -273 degrees C. Water freezes at +273 Kelvin and water boils at +373 Kelvin.
If we put a thermometer in darkest space, with absolutely nothing around, it would first have to cool off. This might take a very very long time. Once it cooled off, it would read 2.7 Kelvin. This is because of the "3 degree microwave background radiation." No matter where you go, you cannot escape it -- it is always there.

for the time of the lunar day, the floor temperature averages 107 °C, and that's barely the floor. there is not any air on the Moon to make the astronauts "warm" or "chilly". they only ought to handle the direct warmth radiation from the solar, and somewhat warmth radiation from the floor, which their spacesuits furnish adequate insulation from. the explanation there are such extreme temperatures on the floor is using the fact the day/evening cycle on the Moon is exceptionally much one month long. The astronauts have been on the floor purely for some hours at a time, the longest "moon walk" being 7.6 hrs long.

They couldn't feel the temperature of the area around them. They only felt the controlled temperature inside their space suits.

They experienced the temperature inside their space suits. Oustide the suits it was a vacuum so there was no temperature - there is nothing to be hot or cold.

The moon temperatures have a extreme range from 100C at noon to -173 C at night

72 degrees and sunny inside their space suits.

the person who responded by saying temp is not well defined in a vac is talking rubbish. i work as a operations engineer and work under constanc vacs where we monitor the temp.

Probably about 75 degrees as they were under Film Set Lights in a studio!

temperature isn't well defined in a vacuum.
