In most cases, it does slightly. But remember that the temperature has also dropped. It is the combination of temperature and humidity that creates human comfort, and Evaporative Air Conditioners are used so widely around the world because they can create comfortable conditions. For example, 80% humidity and 30 C is very uncomfortable, but 80% humidity and 16 C is quite comfortable. Furthermore, comfort is also improved by increasing air velocity in hot conditions and Evaporative Air Conditioners create sufficient air movement to also minimise the effects of humidity.
