Why does it get a little cooler after the rain?

Water, evaporating, absorbs a huge amount of heat from the surrounding nature. For example, when 1 liter of water evaporates under the most favorable conditions (at boiling point), water absorbs 2.3 million joules of heat. After rain, very favorable conditions for water evaporation come: the air temperature is positive, the contact surface of air and puddles or wet surfaces is large; however, wind may be present, which enhances evaporation. This leads to abundant evaporation of water and absorption of heat from the surface of the earth and from the surrounding air. Therefore, it gets a little cooler after the rain.
