A dewpoint of 60 F is almost unnoticeable to me; just enough that it feels like summer.
Actually a high of 80 F and a dewpoint of 60 F is the most typical weather of July
and most people here don't notice or mind.

80 and a dewpoint of 60 is a heat index of about 81. As far as I'm concerned, any heat index above the temperature is humid and any heat index below is dry.

Not sure what the heat index was but the worst I ever felt was in Philadelphia where it was 103 with a dewpoint of 84.
I have felt 120 dry degrees in AZ and that was not as bad.
Coldest was -30 in MN. (and then I got on a plane and flew home to AZ where it was 75)

I agree, a dewpoint of 60 is nothing. Infact, by Mebourne's summer standards, that would be considered humid!!!!! In Melbourne, dewpoints above 70 are rare, and only occur during summer rainstorms and often last less than a few hours. The typical summer dewpoint here would be mid 30's to about 50.

Drier than here, but I'm pleasantly surprised it's not excessively dry. Is it because of the ocean?
Typical Toronto summer dewpoints here are high 40's to mid 60's.

Oftentimes meterologists will come up with standards for dew point ranges 50-59 being noticeable, 60-69 uncomfortable, 70-79 oppressive.

I agree that a 60 degree dew point is not uncomfortable, but 84 is VERY uncomfortable for nearly all. 84 degree dewpoints aren't even normally experienced in the Amazon. The only places that get 84 degree dew points regularly are coastal Eritrea and Djibouti, often combined with temperatures over 100.

That's craziness. The highest dewpoint every experienced in the world is 93 degrees. So you're telling us if it was 95 degrees outside with a dewpoint of 94 (heat index of 157 degrees BTW), it wouldn't be humid?

There is a certain point up to which at 60 degree dewpoint is uncomfortable for some. A 75 degree day with a 60 degree dew point equates to a heat index of 77, which some don't like

Actual temperature was about -35, wind chill -70 in Chicago (think it was on Christmas Eve in the early 80s). Other extreme was 112 degree day in Dallas Texas

I do not know about the wind chill, I don't think they had that report in 1963, but the temp was 50F below 0F at the ranch in Nevada that we lived on. The fuel froze up in the big machinery, and in the fuel line to our house. 40 below was not uncommon at the high prairie in Idaho where I was born and raised.( Camas Prairie, in Camas County.)

no, i think you misread his post, he's saying if the HEAT INDEX is below the actual air temperature, than the air is dry, and if the heat index is above the air temperature than it's humid.
