How does the amount of moisture in the air impact how uncomfortable it feels outside? Well, the reason why more humid air feels warmer to us is that we keep cool by evaporating moisture from our skin (perspiration). Evaporation is a cooling process and the higher the humidity, the less evaporation that occurs and the warmer we feel.
Also, with less moisture in the air we will see a much more significant cool down at night. Spring and Fall, when the air is drier, we see a much wider range in temperatures from daytime highs to nighttime lows.
So, as we look for different ways to say “Hazy, Hot & Humid” this summer, remember, it’s not the heat, it’s the dewpoint!
