I did this from taking 98 with 90% humidity which is a typical Dallas day and doing 105 with 0% humidity which is a typical Palm Springs day.

Sounds legit.

Both are better than Chicago in July. 100 F with 100% humidity every day. Once October 1 hits, it drops to -70 F with 100 mph winds and endless blizzard conditions.

In reality, they are a wash

July

Normal High Temp= 109 vs 97
Normal Dew Point= 51 vs 71
Normal Heat Index= 107 vs 105

That's the average maximum dewpoint, which is unlikely to occur at the time of the high temperature.

No that is in fact the "AVERAGE DEWPOINT" used by calculating the average relative humidity versus the average mean temperature.

So for Dallas, avg mean in July is 86.5, and average humidity is 60%. That is an average dewpoint of 71.

Likewise, Palm Springs, avg mean in July is 95, and average humidity is 23%, which is an average dewpoint of 51

Dallas's average July dew point is 71.7 F, but only 70 F for DFW.

That's not how it works.

Did you average all the months yourself?
