Why isn't there a wind chill to make it feel cooler? With wind and low humidity, there has to be some evaporative cooling.
Today it feels hot, but not oppressive like last July when it was so (typically) humid.
I remember the first week of last July. I was at an airshow on the tarmac and it seemed it was 100 F and 90% humidity. It was mostly sunny but some clouds and if a cloud passed by the sun it'd temporarily cool the air enough that rain drops fell out of the atmosphere. That's humid.
I thought about wind chill the other day that if the temperature is near or above your body temperature 98.6, the wind would have no cooling effect. Someone I know in Pheonix told me that the humidity is so low that heat index can be lower than the actual temperature.
They need a heat index for being in direct sunlight. That's got to make it feel hotter as does humidity.
