Newark hit 128.2°F/53.4°C heat index at 7.00 PM with 99.0°F/37.2°C and 84.0°F/28.9°C dew point.
I doesn't find the Central Park stats for this day in wundeground.
2011 heat wave :
On the July 22 2011Central Park hit a 114.9°F/46.1°C heat index with 102.0°F/38.9°C and 73.9°F/23.3°C dew point at 12H51 PM. : http://www.wunderground.com/history/...q_statename=NA
The hottest temperature on this day in Central Park was 104°F/40.0°C.
But I don't find the highest heat index ever recorded in NYC.
Agreed, but look at it this way. Take the average high and low temperatures in Chicago and NYC for any given year From June to September. Then, on the whole, tell me which city has warmer temperatures. That would clearly indicate heat in NYC is more prolonged, though less extreme than Chicago.
If you are talking about the average mean temperatures NYC would have a slight advantage because of it's warmer minimum temps, but not by a huge margin. If you are talking about max temps they are nearly identical. However the topic of this thread is about "worse" heat as in extreme heat right? If so, then based on the records, Chicago would edge NYC, not by a huge margin, until you get out into the suburbs. You suggest that it is cooler in NYC's suburbs right? In Chicago's suburbs the minimum temps are cooler then the city, but the max temps are a warmer.
For example west suburban has an average high of 87F/31C in July a couple of degrees F warmer than Midway
Aurora in 1936. Insanely hot. For a 12 day period, the average high was 104.2F/40.1C

Chicago has the lake to help with cooling NYC does not have this advantage AT ALL. In fact, people head up the Hudson valley and to the Catskills every year for cooler relief. Otherwise, they head east to Long Island.
New Yorker's don't take advantage of the Atlantic Ocean to escape the heat? How is that any different than going to the beach on the lakeshore?
Speaking of lake cooling.... The city of Chicago's highest temperature ever recorded when Midway hit 109F, there was lake cooling at the official site which was at the UofC back then.

I would say Chicago. Over all the average temperatures almost identical during the summer as well as dew points, but Chicago has greater swings of extreme weather being in the interior. Chicago has had a higher record monthly average max then NYC. Midway recorded 92.1F in 2012, and a 109F record absolute maximum in 1936
NYC recorded 90.7F in 2010, and an absolute max of 107F in 1966 (108F in 2011 @ EWR), not a huge difference. And I don't get why a one time event would be more significant than one city actually being warmer than the other overall, on a consistent basis. Midway's average July temperature is 76F, LaGuardia's is 78F. LaGuardia's average annual maximum is higher than Midway's as well.

We aren't discussing annual maximums or mean temps. Knowing Harford's posts, I'm sure his intention is about comparing extremes. I thought the topic was on "worse summer heat". if the topic of this thread is about "worse summer heat", then Chicago has had it "worse" than New York right?
More 90 degree days in a season: Chicago
More 100 degree days in a season? Chicago
Higher maximum monthly temp: Chicago
Higher absolute maximum temp: Chicago
Higher absolute heat index: Chicago
Btw, this is NYC's hottest month. As you said in July 2010 LaGuardia recorded NYC's hottest temp

I don't compare climates based on their extremes, especially when their extremes are similar, it makes little sense to me. The two are similar in terms of heat, but I give the slight edge to NYC since it's consistently warmer.
There are different ways for heat to get to the 2 cities here's one of them. This was over the summer.
But since NYC is near a larger body of water I will say Chicago has worse heat. It's easier for winds to come in from different angles in NYC but Chicago needs specific winds from the Lake.
For humidity NYC takes the cake. Even though both cities get it streaming from the gulf, NYC being near the larger body of water makes it worse.
Heat index is a different animal and I'm not sure.. Toss up

I agree with your overall assessment, but then how do you explain this?

My guess is that dew points are probably identical, but like extreme heat, Chicago can see, spikes higher and in more frequent occasions than NYC in part due to the farmland around us. I don't know enough about NYC's dew point levels to say for sure though....

Wait, in terms of city limits, yes, NYC and Chicago are not too different in heat extremes, though Chicago has the advantage. However, comparing the entire metro areas of both cities, then Chicagoland blows Greater NYC out of the water. There is no station within 500+ miles or greater of NYC that has ever had an average max of 100F in a month. There are at least two stations within 55 miles of Chicago that have, and multiple stations that have had average monthly maximums above 95F.
Collegeville is about 45 miles from my house
Chicago (Midway) has had a higher record average max than NYC in June, July, and August, and I suspect, May and maybe September too, but you can chime in and correct me if I'm wrong.
It does make sense when we are talking about extreme temperature variations or records right?

They are similar, and yes you are correct, the average high and mean at the warmest NYC station (LaGaurdia) is slightly warmer then Midway during the summer season. The UHI and the proximity to the Atlantic keep the minimum temps elevated a bit higher in NYC. Chicago's minimums fall off dramatically in the suburbs away from the UHI and Lake Michigan's insulation, more akin to the true Midwestern diurnal temperatures.
NYC Central Park: 82.8F----74.8F
La Guardia: 83.0F--- 75.6F
JFK: 81.0F---- 73.7F
Newark: 84.5F---- 75.8F
Plainfield NJ: 84.8F---- 73.8F
