It is so hot I think I am going to throw up.

The heat index is a way to account for this combination of heat and humidity.

In Fahrenheit



In Metric



According to Wunderground, right now in London, it's the early afternoon, and the temperature is 82 degrees F and the heat index is 82 degrees F. In Arlington VA right now, it's mid morning and the temperature is 87 degrees F and the heat index is 100 degrees F.

Admittedly, I'm sitting in air conditioning right now, but my morning commute was pretty gross, walking to the subway station.
