Like the saying goes "it's not the heat, it's the humidity!"
Residents of South Florida are complaining about the heat, but daytime temperatures have been very close to normal for the past three days.
Sunday's high of 91 reflects the normal high temperature for early July, while Monday and Tuesday’s highs were 92, just one degree above normal. Factor in the humidity, though, and the heat index climbs close to 100. The heat index is a measure of how the human body feels when combining the air temperature and humidity levels.
In higher humidity, the perspiration process does not work as efficiently because sweat does not evaporate as easily off the surface of the body. Therefore, we tend to feel a lot hotter than what the temperature reading is. There hasn't been much relief at night, as humidity tends to climb, and night time temperatures have not dropped below 80 in three days.
Meanwhile, much of the rest of the country is immersed in a heat wave.
At least twenty states are under some form of heat advisory today due to temperature readings in the 90s and 100s, and heat indexes of up to 110 degrees. Most of the states affected are in the Midwest as well as the Southeast.
Florida is not currently under any type of heat advisory.
