Wouldn't 88° at 60% humidity put the heat factor somewhere in the 92° range, if not higher?

Yours is the first mention of Heat Index.

88 degrees, at 60% RH (which puts the dew point at a reasonable 72 degrees), puts the Heat Index at just over 95 degrees.

And yeah, here in SC we've had 90°+ days combined with high 80s humidity ... it's not that uncommon.

In order to have relative humidity at 88% with a temperature of 91 degrees, the dew point would have to be 87 degrees. That would also put your hypothetical Heat Index at 125 degrees.

That almost never happens in sub-tropical/temperate North America.

In Baton Rouge, dew points of 80 degrees are fairly common in July and August, as are high temperatures of 95 degrees. Those conditions put the relative humidity at 62%, which doesn't seem high until you calculate the heat index for 62% at 95: 115 degrees.

Sunday at 3 o'clock in Baton Rouge it was 92 degrees with a 75 degree dew point, 58% RH, which gave us a heat index of 103.3 degrees = hot as shite.

Use these:

Temperature, Dew Point, Relative Humidity

Heat Index

...and you'll never claim, "100 DEGREES WITH 100% HUMIDITY!!!1!!" again.
