Evaporation is one of the four principal ways that heat can be transferred (the other three are radiation, convection, and conduction). Evaporation of sweat from the skin is an endothermic reaction: the reaction essentially "consumes"...

This is why evaporation is a cooling process. The molecules of different liquids hold on to each other with different amounts of force. For liquids that hold tight, a great deal of energy is required for a molecule to break free.

To simplify this a bit, think of evaporation as the process of that molecule leaving. Well, since only our warmest molecules will be leaving this way, the average temperature begins to drop. Thus, we can call it a cooling process.

The cooling effect of perspiration evaporation makes use of the very large heat of vaporization of water. This heat of vaporization is 540 calories/gm at the boiling point, but is even larger, 580 cal/gm, ... The cooling process is an example of the approach to thermal equilibrium. The evaporative cooling rate is given by...

Evaporation Cooling Experiment ... The process works best when there is a good flow of air and the relative humidity of the incoming air is below 30%. The efficiency (cooling effectiveness) goes down with an increase in the relative humidity of outside hot air.

In Colorado, because of our semi-arid climate, evaporation happens very quickly. Evaporation is a cooling process. That is why we sweat and why breezes off of bodies of water are cool.
