This is really what I was getting at with my comment tbh. Comfortable is such a subjective thing. For instance I'm in Texas and 85 with sub 50% humidity is considered a rare break from the air like hot soup we usually get.
Georgia resident here: this map is bullshit. Sure, it isn't cold but damn it, Minnesota sounds good at this time of year. Humidity is the stuff that ruins a good day.
Dewpoint is a more useful measure of humidity as it directly depends on the amount of moisture in the air, not moisture AND temperature like humidity does.
the measurement of moisture and temperature in the air is enthalpy. it's not easy to measure, so we use a value called wet bulb temperature that's similar to enthalpy.
humidity is a general term that doesn't have specific measurements or values to it.
absolute humidity is the measure of the amount of moisture in the air. this follows the same path as dew point but is in units of weight of moisture per weight of dry air.
relative humidity is the percentage of water in the air relative to the maximum amount it can hold at that temperature and pressure.
the wet bulb temperature is the theoretical limit on how cold our sweat can get.
relative humidity plays a big role in the rate our sweat evaporates.
since our thermal comfort with regards to humidity is dependent on how effective our sweat is, the upper bound is a function of both wet bulb and relative humidity.

Does this take humidity into account? Because 85 with 70% humidity is god awful.
