I've said it for years, heat index and wind chill are only observed by humans. Machinery, animals, plants, all they know that exists is actual temperatures.
Yeah, the best week and a half of the year.
Habla espanole?

Wind chill will affect pretty much any animal or humans. Wind chill can be very dangerous because the moving air will more rapidly remove heat from the body. It's exactly why a fan helps to cool you when you're hot. It will affect inanimate objects but only by lessening the amount of time it takes for that object to cool to the ambient air temp.
Heat index is real, also. At higher humidity levels your perspiration doesn't evaporate so it doesn't cool your body like it's supposed to. Therefore it seems hotter than it really is.
It's similar to the Wet Bulb temperature. Sustained exposure to a wet bulb temp above 95° is very dangerous to humans. At that temp the body loses the ability to shed heat and starts to absorb it from the environment.
I don't know if it's used by global climate change activists or not but it's a real measurement of the real affect of heat and moisture in the air. As a weather forecaster for the Air Force it was something we routinely briefed the wing commander on for those required to work outside...like on the flight line...in summer.
No I will just mow around 9 in the morning or pick my days.
