During the lunar day (which lasts about 14 Earth days), the surface of the Moon can reach temperatures of around 253 degrees Fahrenheit (123 degrees Celsius).
However, it's important to note that:
* These temperatures are only at the surface. The Moon's interior is much cooler.
* The temperature varies greatly depending on location. Areas that are exposed to direct sunlight will be hotter than areas that are in shadow.
* The Moon doesn't experience weather like Earth. There's no wind or rain to distribute the heat.
So, while the lunar day can be quite hot, it's a very different kind of hot than what we experience on Earth.
