What is dew point temperature?

Air can hold water molecules. The warmer the air is, the more molecules it contains. The colder it is, the less water it can hold.

If air humidity is 100%, it means that the maximum possible number of water molecules is in the air and it cannot take any more.

Usually, warm air rises up from the ground. The higher it is, the cooler the air mass gets, and the less amount of water it can hold. Excesses of water appear, and we see a cloud.

The dew point is the air temperature at which its relative humidity reaches 100% and water vapor begins to "precipitate", that is to condense.

In other words, the dew point is the temperature to which the air needs to be cooled so that water condensate is released from it (dew appears).
