Yes that is horrid. When the the dewpoints are over 80F you have to not exert much energy.

What's the highest dewpoint you've experienced since you've been living in the Chicago area?

My personal best is 82/83 while living in Ft Lauderdale.

I didn't bother stepping outside to feel the 76 dp we had earlier today...lol. Too busy making plans to escape this hellhole.

July 30th 1999 when the dew point reached 83F/28C at ORD. Back then I lived in Albany Park on the Northside of Chicago which is about 9 miles from ORD



Since then I've experienced more than a dozen days of 79-81F dew points here in the far south suburbs. Three 81F dew points in a row in July 2011. And nine 79F/26C dew points during the summer of 2010

About like me, then.

I honestly think I'd have a panic attack if I was subjected to an 83 dp now - feeling like not being able to breathe, etc. A dewpoint above 99 would actually kill a human if they stayed out in it long enough, since water would condense out in a person's lungs.

95 is the highest ever recorded - just four degrees away from the "death zone." Yikes.

Yup that would be the Persian Gulf Coast.


Appleton Wisconsin probably holds the US record for highest dew point (and heat index)

But it was during the July heat wave of 1995 that the highest dew point of all was measured in the Upper Midwest: 90° at Appleton, Wisconsin at 5 p.m. on July 13th of that summer. The air temperature stood at 101° in Appleton at that time leading to a heat index reading of 148°, perhaps the highest such reading ever measured in the United States. Here are the METARS for Appleton that day:

Interesting info and I always wondered about that.. how high can it go before the human body really shouldn't be subject to it.

I know I experienced low 80s in my life just don't remember when. But I know I feel the difference from like 68 and 73 alone. Ironically I don't feel the differences when it's bone dry..(20s vs teens)

Mid-upper 70s feels like my lungs are collapsing. lol Obviously the longer I'm outside the worse it feels but above 72 here is downright oppressive.

It feels worse here than in the Tropics or Florida. Wind plays a big role.

Now the difference is felt with the soils and surroundings. I bet i still feel worse than that with the same numbers. Sandy soil vs clay. Dense woods vs more open there. I bet it feels more suffocating here then there.
